Emergency Equipment for your MINI

Even if you’re never going to be more than a few miles from home, but especially if you’re venturing out on longer tours, you should equip your MINI with some basic emergency equipment. Put it in the glove compartment or in one of the rear stowage areas and leave it there. Check to make sure that everything is in place whenever you head out on the highway. Your emergency stash should include the following:

Never leave home without your cell phone and buy a charger for it that you can leave in the car all the time so you never have to worry about being low on power. Subscribing to an emergency road service such as available through most major auto insurance companies and having their telephone number in the car will take care of most emergencies.

A major credit card and a telephone credit card are also absolute necessities so that you can pay for a tow or emergency repairs, and make a phone call in rural areas where you can’t get cell phone service. In addition, tuck some money in five dollar bills and some quarters for the phone in an envelope in the glove compartment. Cash money may be all that’s accepted if you need to have your chains installed or convince a tow truck driver to help you out.

A flashlight is essential for many applications. One of those emergency lights that can plug into your car’s power source, plus a handheld flashlight that can be used to check a map, wave at oncoming traffic, or shine into the engine compartment are both good pieces of equipment to have. To protect yourself if you break down in high-traffic situations, you should also have some highway flares or tripod reflectors that can be placed behind the car to warn oncoming drivers of your presence. Any major hardware store or auto supply store will stock a neat kit with these kinds of supplies for your car.

A tire repair kit in a pressurized can, and a 12-volt tire inflator should also be part of your emergency kit. These kits are easy to find in catalogs, hardware, or auto supply stores. Incidentally, if you do get a flat tire on any heavily-traveled highway or road, don’t attempt to repair the flat on the shoulder. Instead, drive to the next exit and get completely out of traffic before attempting a repair.

You should have a small notebook, a pen or pencil, and an accident check list tucked in your glove compartment. In case of an accident, you’ll need to get the name, address, driver’s license number, tag number, and insurance contact information for any other drivers involved with you in an accident, as well as the names, addresses, and phone numbers of witnesses. Keeping a small disposable camera in the glove compartment also is a good idea so you can shoot pictures of the accident scene and the cars involved for use if any legal or insurance claims later arise.

You should also carry a good plastic flashlight and spare batteries to use in dark corners or under the car, as well as for after-dark emergencies. An emergency light that plugs into the power socket is nice, but might not work if your battery goes flat.

Even in high summer, a blanket is a useful piece of emergency equipment, and in winter weather it is critical. You can lay on it to check under the car, wrap up in it to keep yourself warm, or rig a shelter to keep off the sun.

If you’re going to be driving outside of urban areas, and especially if you’re driving in very hot or very cold conditions, a gallon of water that can be used for drinking or put in the radiator is worth having in the car. A day’s worth of calories for every passenger in the form of high-protein energy bars is worth tucking in. Even if you’re not stranded, hunger or thirst can ruin an otherwise nice trip.

Even if you are a complete klutz at auto repairs, having a set of basic tools and some emergency repair supplies. tucked in a plastic or canvas tool kit, can be a good idea. At the very least, combination pliers, a lineman’s wire-cutting pliers, a flat-head and a cross-head screwdriver, a medium-size combination wrench, a coil of repair wire, a roll of duct tape, and a roll of electrical tape can be very useful. With these few tools, you—or a helpful good Samaritan with some mechanical ability—can make a variety of stopgap repairs that will at least get you off the highway and to the next point where you can get cellphone service to call for emergency assistance.

Bad Weather Conditions

When you’re a long way from home and the weather turns bad, you may not have much choice except to deal with it. Rain, fog, snow, or ice can happen at the most unexpected times and places, and you should be mentally ready for the possibility.

Just as on the track under wet conditions, as soon as it starts to rain even a little bit, you need to slow down. Especially during the first rain of the season, oil and rubber that has sunk into the pavement will float back up to the surface very soon after the rain begins. Oily, wet pavement can be every bit as slippery as icy pavement and caution must be your first rule.

The same rules apply for highway driving in the wet as on the track. Make your changes in speed and direction as smooth as possible. Try to stay off the most heavily traveled section of pavement. Staying in the slow lane will allow less sensible drivers to get past you, as well as giving you a better chance of avoiding trouble if the problem arises.

If the rain gets very heavy, your best bet is to tuck under an underpass or preferably get off the highway completely to wait for it to let up. Visibility can go to zero almost instantly and the wet pavement can make it difficult to stop if someone in front of you skids sideways or stops without warning.

Fog is also a hazard that is underrated by many drivers. The moisture can make the pavement slippery, and visibility can be erratic. Because fog can gather in low-lying areas, you can easily drive into a space where visibility is only a few feet or less. Be aware of this, and if you see a thick area ahead, slow down to a crawl before trying to get through.

Fog lights are helpful, but are not a cure-all. They do focus the light beams on the pavement immediately ahead, rather than reflecting it off the fog, but do not give penetrate the fog any more than regular beams. In any case, make sure you’ve turned off your high beams. If you have high-intensity rear fog lamps, turn them on so the cars behind you can see you better.

In snow and ice conditions, caution is critical. Not only is it easier to lose control of the car, but if you slide off the road in cold weather, even survival can become a challenge. One of the most dangerous times to be driving is when the temperature hovers right around zero. Melted snow or rain on the pavement can easily turn to ice, especially on bridges and overpasses. Keep your speed down, and be very sensitive to any feeling of loss of control.

Again, make changes in speed and direction cautiously and smoothly. If there is snow on the road, you are generally better off driving with at least one front wheel in the snow because the grip will be better there than on the portion of the pavement cleared by the wheels of other vehicles. If you do need to put on chains, of course they go on your front wheels, since these are both your power and your steering wheels.

Above all, don’t be in too much of a hurry to complete your journey if the weather turns unexpectedly bad. Be willing to get off the highway and hold up in a restaurant or motel until things get better.

Just be aware that you don’t want to get off the highway unless you are sure you’ll be able to find your way to a safe and secure place to stop. In bad weather, the back roads are likely to be less well patrolled than the main highways and the worst place to be is in an uninhabited and unpatrolled area.

Back Road Techniques

Passing on the Backroads

Because we are so blessed in this country with freeways and limited-access highways, the old techniques of passing have largely been forgotten. They’re rarely taught in driving courses, except to emphasize not to cross a double-yellow line, and there aren’t many opportunities to practice the technique.

However, the more time you spend exploring the two-lane byways, the more often you’ll find yourself in a situation where you really do want to pass that slow-moving vehicle up ahead. To make a pass safely on a two-lane road just requires keeping a few guidelines in mind, then cultivating your ability to gauge the “closing speed” of your vehicle and the one coming at you from the other direction.

Obviously, there can never be any passing across a double-yellow line, or when there is a solid yellow line in your lane. To emphasize this, in most states there will also be a roadside sign stating “No Passing Zone” wherever visibility ahead is too limited to permit safe passing, and “End No Passing Zone” when there is sufficient visibility ahead to permit safe passing.

The first point to keep in mind in passing safely is that you need enough room to accelerate to a speed faster than the car immediately ahead of you, then you need to get far enough ahead of them to be able to safely return to your lane without forcing the car you just passed to slow up abruptly. You could work out the math, but a typical pass will require a minimum of half a mile, so you must be able to see at least that far down the road to make sure traffic is clear and there is enough space to complete your pass.

It is possible to pass even when you can see a vehicle coming toward you from the other direction, but the best strategy is to wait until they’ve passed you, at least until you are confident of your ability to determine the passing distance required, and to estimate how long it will take for the distance between you to close.

Here a second tip applies. When getting ready to pass, you don’t want to be right on the bumper of the car ahead. Instead, you want to have enough room so that you reach your maximum passing speed before you leave your lane to pass. That way, you will spend as little time as possible in the opposite lane before returning safely to your own lane. To do that, you should be at least two to three car lengths behind the car in front of you when you begin your pass.

If there is a vehicle coming from the other direction, and you can see far enough up the road to make sure that there will be space to pass after the oncoming vehicle passes you, then you should prepare to make your pass before the oncoming vehicle gets to your point. To maximize the amount of time you have to complete your pass, you should begin to accelerate as the oncoming vehicle approaches. If you’ve timed things properly, you will be at your maximum speed and ready to move into the opposite lane just as the oncoming vehicle passes you.

When passing, it is worth keeping in mind that it is illegal in all states to exceed the posted speed limit on any road or highway under any circumstances. In other words, if the speed limit is 65 mph, and you come up behind a farm truck going 45 mph, you’re permitted to go up to 65 in order to pass it, which isn’t a difficult pass. On the other hand, on that same road, if you find yourself behind a cautious driver doing 60, if space permits, you are allowed to accelerate to 65 to pass him. However, you can be ticketed if you have to accelerate to 75 mph in order to pass him.

Back Road Driving Techniques

Chapter Sixteen


Touring the Back Roads

Even if there aren’t any opportunities for track days or autocrossing in your local area, or you just don’t feel comfortable putting your new MINI through that kind of ordeal, touring can be a great way to enjoy time with friends, see the scenery and sights in your region, and have some fun with your MINI.

But even on pleasant grand tours, there are some advanced driving tips that can make your time on the road safer and more fun.

When The Route’s Brand-new

One major difference between driving on a track or autocross course, and driving on a tour on public roads is that you can’t learn the course in the same way. Even if you’ve driven a section of road frequently, you still can’t memorize the turn-in points and apexes of each corner the way you might on the track. So your mind-set must be different for touring. When you can’t be sure what the rest of the corner will look like, the major goal is to keep your car under control, rather than attempting to push its limits.

In particular, on roads that are new to you, you need to be aware that the curvature of the corner may change as you come around it. What was a reasonable speed when you entered the corner may be too fast for the radius of the curve on the other side.

Similarly, you may find that the easy corner is followed, right around the bend or just over the next rise, by a much tighter corner that you aren’t ready for. Generally, that means staying well within the limits established by the road and geography, rather than those determined by the car.

Old hands at road rallying suggest a trick to deal with blind crests that can help a little bit. If you’re coming up a rise or hill, and can’t see where the road goes after the crest, look at the telephone poles or tree line. Generally they’ll give you a clue to whether the road curves over the crest, and in which direction, or continues to go straight.

Nonetheless, whenever traffic permits, the twists and turns of a good backroads route can still allow you to enjoy the handling and power of your MINI. Generally, it can be more challenging to drive a two-lane back road near the 45 mph speed limit, than it is to drive a divided highway at 70 mph.

Be Ready for the Unexpected

Unlike the race track, out on the road, you don’t have a person with a yellow flag standing right at the apex to warn you if there’s an obstruction right around the bend. Instead, you’ve got to keep your speed limited to the level where you can use your reflexes and brakes to bring the car to a safe stop, or steer around the obstacle, without violating the laws of physics.

To be safe, you simply need to be aware of those times when you can’t see around the corner, and so need to slow down to the speed noted on the caution sign and be alert to what’s on the road as you do round that blind corner.

Don’t forget that you can drive around many obstacles rather than trying to stop to avoid hitting them. Often the safest course is to make a quick, slight direction change, rather than trying to stop.

As you drive, try to be conscious of what the sides of the road look like, as well as the road itself. If you do encounter that recreational vehicle stalled in the middle of the road, you need to know whether your only option is to slam on your brakes, or if you can safely go off on to the shoulder to avoid hitting the RV.

Track Day Driving Techniques

You Can Learn a Lot by Watching

In between your runs, you also need to use your time effectively. After your first run, you may have some idea of which corners are toughest, or where you seemed to be slowing down too much. Watch the other competitors to see what line they’re taking through that portion, and watch where everyone seems to be having the greatest difficulty. As you watch, try to visualize in your mind what the course looks like from the driver’s windshield so you’ll have an idea of where to go when you’re on the course.

Many autocross events will require competitors to act as corner marshals on the course, with their primary task to replace cones that are knocked over and to help the starter make sure the corner is clear. These are excellent opportunities to get up-close-and personal as other drivers run the course. Check out the techniques of the fast drivers and see how they are taking specific corners. Their experience may help you take seconds off your own time.

Track Day Driving Techniques

High-Speed Straights and Sweepers

Autocross courses are great places to find the limits of your car. In particular, most courses will include at least one high-speed sweeper. On these corners, you’ll want to get your car right at the edge of adhesion. You’ll be able to tell where that is by the squeal that the tires make as they struggle to hold on. You’ll often hear the saying, “A squealing tire is a happy tire,” but you won’t know what that means until you turn your car into that long curve then push down on the throttle until the car is right at its limits, using the throttle as much as the steering wheel to keep the car on course.

Gear selection and shifting is one of the few driving techniques that you probably won’t get to practice much when you’re autocrossing. Because most courses are so short and tight, you’ll probably find that you start in first, shift up into second as quickly as possible, and then stay in second gear for the entire course.
Occasionally an event may be able to set a course that does include one or perhaps two very long straight sections, where an upshift into third is needed towards the end to keep on the power band or avoid exceeding the rev limits. Even on these courses, you’ll need to downshift again almost immediately to be ready to power through the next corner, so you won’t lose much if you just run the car up to the top of the rev range without shifting.

Starts and Finishes

Nearly all autocross courses are timed electronically, with a beam of light and electric eye at the start and at the finish. As you make your start and cross the finish, your car breaks the beam of light, starting and stopping the timer.
For safety purposes, the SCCA has had a long-standing rule that there must be a right-angle turn before the start line, and another right-angle turn before the finish line. The cones that mark the turn before the start line, and after the finish line count just as much any other cone on the course, so you have to be careful in your start and finish. These rules help assure that cars don’t enter the course or leave the course at unsafe rates of speed.
The most obvious tip is that you want to be going as fast as possible when you cross the starting line, so that you begin the course with as much momentum as possible. Similarly at the finish, you don’t want to slow down until you’ve crossed the line and are off the course.
But you don’t want to be faster off the mark than the course permits. On many courses, the person setting the course will set up the first obstacle in such a way that the real hotshoes will find themselves in trouble as soon as they’re across the starting line.
When you walk the course, and as you sit at the start line waiting for your signal to begin, have a plan of attack on how you should negotiate the corner into the start line, based upon the direction you need to be going for the next two or three corners.
Similarly, there may be a complicated set of turns going into the finish that can trip up the unwary, causing them to be off the throttle just when they need a fast finish. Keep these possibilities in mind as you walk the course, and plan your strategies accordingly.
Gearing isn’t quite as complicated. With the MINI, your best bet on most courses is to start off in first, and then shift up into second as soon as you can. For the rest of the course, you can then just stay in second, confident that you’re well up in the rev range where you’ve got good torque for maneuvering. Few courses offer enough space to build up sufficient speed to justify a shift up into third or to require a downshift into first, and in most cases, the time you might gain by being in a better rev band will be lost by the time it takes to make the shift.

Setting Up the Car

During your first season, you don’t need to make many changes to the car. Most of your improvements in time will come through improvements in your own driving skill. In fact, the SCCA stock class places significant limits on what you can do to the car. In these classes you can make only a few changes to the engine. You can substitute a more efficient air filter, and replace the exhaust system behind the catalytic converter, but that’s about it on the power side.
On the suspension, you can substitute adjustable shocks and a front sway bar to reduce the car’s tendency to understeer. However, with the MINI’s excellent stock handling capabilities, it may take a season of practice before you would notice the difference in your time by these modifications.
What you can do within the limitations of the stock class is to replace the wheels and tires, so long as you stay within the stock sizes. Here you can make a great deal of difference in your lap times. As we’ve discussed above, by replace the stock wheels with a lighter-weight set you give the engine less mass to move. By mounting some good-performing tires to replace the run-flat tires that came with the car, you can get much better traction, and reduce the unsprung weight to boot.
If you get serious about autocrossing, you might consider buying tires that are designed specifically for racing, with a softer compound. However, these tires won’t last long at all if they’re also used on the street, so you would have to mount them on a separate set of wheels and put them on the car after you arrive at the event. Making this investment can certainly wait until you’ve worn out your first set of street tires and have gained the skill to take advantage of the improved tires.
But even if you decide to use the original run-flats for your first few events, experienced MINI autocrossers suggest that you can accomplish a lot by adjusting your tire pressures. You’ll probably want to increase the pressure on the tires so that they are less likely to roll. Inflate the fronts with about four pounds less pressure than the rear and you’ll do a lot to reduce the MINI’s basic understeering tendencies.
Another tip to find the right pressures is to make a mark with chalk or white shoe polish on the tire at the point where the tread joins the sidewall. If the mark is worn off after a run, then the tire is rolling over too far and you should increase the pressure that you’re running. Experiment with different pressures over the course of several sessions until you find a level that works best for you.
Be sure to check that the lug nuts are tight while you’re adjusting tire pressure and before going out on the track before every run. To be absolutely sure that they’re tight, you’ll need a “torque wrench” which measures the pound-feet of pressure required to twist the lug nut. You don’t need the best quality, since you won’t be using it every day, but a good one can be purchased for about $50. Tighten the lug nuts individually to 80 pound-feet and you’ll be sure that you won’t be singing, “You picked a fine time to leave me, loose wheel.”

Finding the Fast Line

Walking the course ahead of time can make a big difference. Since most autocross events only allow the drivers two or at most three runs, there really isn’t enough time to develop a strategy for the course and figure out the best line while driving it. Instead, serious competitors will arrive early enough so they can walk the course and scope it out.

When you do walk the course, try to ignore the rest of the crowd. Don’t just walk around to see where it goes; instead look at each corner, or sequence of corners and pause long enough to figure out how to go through that portion most quickly.

As you walk the course, divide it into cornering sequences and straightaways. You want to be in a position to get on the throttle quickly going into a straightaway, so that may sometimes mean planning your line through several corners in such a way that you can come out of the last corner at the right point and pointed in the right direction to burn up the straight.

The best strategy to deal with a sequence of turns leading up to a straight is to work backwards. Start with the straight, looking at where the car will be straightened out and pointed in the proper direction, then figure out how to take the previous corner so that the car winds up at the right point, facing in the right direction. Then evaluate the next previous corner and so on until you’ve figured out where you need to enter the sequence and how you should take it.

Autocross courses are typically made up of standard right and left turns, plus some ingenious obstacles that will be incorporated into every course. These include slaloms, chicanes, 360-degree turns, and sweeping turns. For each of these, we can offer some tips to take them as fast as possible

Slalom Segments

Slaloms are an important part of every autocross course. This segment of the course will consist of a straight line of cones, typically placed at equal distances from one another. The task is to go from right to left to right again, weaving through the line while maintaining as high a speed as possible.

To run a slalom sequence quickly, you definitely need to be looking two to three cones ahead, rather than simply concentrating on turning around the next cone. Drivers who focus on the cones one at a time typically start fast, then find themselves going wider and wider with each turn until they finally reach a point where they have gone too wide and can’t get turned without going off course or hitting a cone.

Instead, you should choose your turning point outside the line of cones, so that you just brush past each cone on the way to the point where you turn to line up to pass the next cone. If anything, you should start the sequence more slowly than you think will be necessary. That way you can gradually gain speed as you go through, rather than having to slide around and scrub off speed in order to stay on course.

Chicanes

Most courses you encounter are likely to have at least one section where the cones extend across your direct line of travel, on an otherwise straight section, forcing you to make a set of three tight turns, for example first right, then left, then right, to stay on course. These obstacles, a favorite of the fiends who lay out autocross courses, are called “chicanes.” (A good term, since the word is the root of the word chicanery, meaning trickery or deception.)

Often the chicane is enclosed in a box of cones to make the problem a little more difficult. A few tips will help you negotiate this obstacle as quickly as possible. First, remember that the main trick to autocrossing well is to turn series of straight lines into smooth curves. Don’t think of the chicane as a set of separate turns, but rather as a sort of slalom, where you want to take as straight a line as possible through the box.

Second, plan ahead to figure out where you want the car to be pointed when you exit the chicane. Then work your line back to determine how you want to enter the chicane.

Third, as you go through the chicane, don’t be tricked into dropping your sight line. Instead, look across and out towards the next turn as you enter the chicane. This will help you find the quickest way through.

Finally, don’t be timid, and don’t be tricked into making your turns sharper than they need to be. Be aggressive at the entrance and make your turns early. On most chicanes, you will be able to get on a straight line and back on the accelerator well before you’re actually through the obstacle, turning what could be three turns into only two turns.

Hairpins and 360 Turns

Another typical element of many autocross courses is the tight hairpin around a cone. Sometimes, the course may even require a 360 turn. This turn will be marked a single pylon sitting in the center of the path of travel with some large open space around it. Your challenge is to go around the pylon, executing a 180- or 360-degree turn and then continuing on the course.

This type of obstacle is tailor-made for the MINI’s front-drive capabilities and easily-reached handbrake. The trick to this is to use the handbrake or your left foot to release the grip of the rear tires on the pavement, then use the powered front wheels to pull you around in a controlled skid.

To manage this, you’ll drive close to the pylon, and when you’re even with it, turn the steering wheel to put the car in a sharp turn around the pylon. Holding the wheel turned with your left hand, you’ll give a quick pull on the handbrake, holding the button down and then immediately release the brake. You can also accomplish the same effect by using your left foot to stamp on the brake pedal and immediately release it, while keeping your right foot on the gas.

Either way, the quick braking should break the rear end loose so you can bring the car around with the nose almost touching the pylon. Once you’re about three-quarters of the way through the turn, you get hard on the accelerator to pull you back into a straight line and on down the course, and allow the steering wheel to unwind.
