How To Race At The Road Course Or Autocross

Ford Mustang Racing At A Road Course

What you Need
Much like ensuring a successful day at the dragstrip, a little preparation before heading to the track can pay dividends that far exceed the investment. To begin with, don't bother to show up unless your car's suspension is in excellent condition. Expired ball joints, rattling suspension bushings, worn tie-rod ends, and shipped-out shocks have no place on a road course or autocross. Road course racing places great strain on all suspension and steering pieces, so it's best to start with good parts. After all, the point of going to the track is to have fun, right?

You'll also need a small assortment of tools in case a bolt loosens up or a leak appears that needs attention. A portable air tank, a small compressor, and a quality air pressure gauge are essential trackside tools that give you the opportunity to make pressure changes to the tires. Most track days that emphasize cars on the course with minimal passing don't require rollbars unless the car is a convertible, but you will need quality seatbelts and a good helmet. NASA's High Performance Driving Experience (HPDE) requires an SA1990, M1990, or newer helmet.

Also bring a cooler with plenty of water, nonsugary snacks or a light lunch, fold-up chairs, and perhaps an expandable tent for some shade during the day. All this might be tough to pack into a '69 Camaro trunk, so you might consider having a friend accompany you to the track with his/her vehicle that can carry the extra gear.

  • Inspecting Car At The Race Track
    Most track day sanctioning bodies will perform a cursory safety inspection to ensure lug nuts are all in place, the suspension is tight, the brakes are solid, and the battery is properly secured. Be sure to read the rules ahead of time and show up with your car in proper compliance. They will not let you run if your car isn't up to spec.

  • Testing Tire Pressure With A Tire Pressure Gauge
    A must-have tool at the track is a high-quality air pressure gauge. Don't trust those cheap pencil gauges-go for a gauge with a large readout for accuracy like this one from Intercomp. The gauge should read out to 60 psi. A tire pyro-meter is a great idea to help with tuning, but this may be a luxury for an entry-level guy.

  • Checking Ball Joints And Other Items Under Your Car
    Spend a few hours under your car checking ball joints, tie rods, and all the suspension fasteners. You might also consider repacking the wheel bearings. While you're under the car, replace that plastic oil pan drain washer with a copper washer. Those cheap plastic washers will quickly melt when subjected to elevated oil temperatures.

Phoenix Systems Brake Bleeding System
You don't need a fancy tool to bleed the brakes, but we had a chance to try out this cool bleeder tool from Phoenix Systems that uses reverse fluid injection to push new fluid into the calipers, which forces air to exit naturally through the top of the system via the master cylinder reservoir. This system can be used on ABS brake systems as well as more traditional brakes.

Track Day Setup
Now that you've signed up for a track day excursion, there are some critical mods that must be done so you have a good time, the car doesn't break, and you don't look like a rookie doing it. An easily overlooked area is the brakes. While open track running takes its toll on tires and the drivetrain, the brakes are easily the place where the abuse is the greatest. This means you should spend a some time giving those binders a little love. Even if this is all you do, always bleed the brakes before any serious shot at a road course. Brake fluid is hygroscopic, meaning it absorbs water right out of the atmosphere. Water reduces brake fluid's boiling point and the brake heat will turn that water into steam, which will make the pedal spongy-or worse-fall right to the floor. So completely bleed the entire brake system before you head to the track. And don't use fluid that's been sitting around the shop in an open container for a year. Buy new fluid and bring extra fluid with you-it gives the appearance that you know what you're doing.

Checking Brakes For Proper Wear And Tear
Aggressive track-style brake pads are a good addition, but make sure they are fully bedded through multiple high-heat cycles to ensure that the friction material has been fully outgassed. If the pads are not fully bedded, it's likely they will glaze, which will seriously detract from braking efficiency. You don't want that.

If you intend to upgrade to a performance brake pad (which is a great idea), be aware that new pads must be properly bedded before going to the track. Bedding procedures vary by manufacturer, but the critical point is that you don't have time to bed the brakes at the track. The best time to do this would be a couple of days before the event, since bedding requires allowing the pads to completely cool to ambient temperature at least once and preferably several times.

Alignment is another important issue. If your car has an improved suspension that has an aggressive front camber curve, then the car can maintain its street alignment and give up very little handling performance. As an example, our mule Chevelle is equipped with a very aggressive Global West front upper control arm that allows us to run 1.5 degrees of static negative camber and 6 degrees of positive caster. The car enters the corners very nicely without the need for additional static negative camber. However, back when the car was equipped with stock upper control arms and spindles, it needed roughly 4 degrees of negative camber to plant the tires. With camber, the goal is to produce even tire temperatures across the face of the tire.

Why Stock Transmission Coolers Are Not Good For Track Events
If your track car has an automatic transmission, don't even consider going to a track day or autocross without a large, high-efficiency trans cooler located in the direct path of cool air. Stock factory trans coolers are not of sufficient size or capacity. Also consider installing a trans temperature gauge and park the car if the temp exceeds 225 degrees F.

Running a car at an autocross is a relatively quick event, much like a drag race, so heat management isn't quite as important an issue as it is on a road course. If you plan on abusing your car on an open track day at a big road course, spend a little time beforehand ensuring the cooling system is in excellent shape. Also remember that at a big track, you are going to be on the throttle for an extended period of time, which will also significantly elevate transmission and rear axle oil temperatures. Consider changing the gear oil in the rearend and in the manual trans with a high-quality synthetic that will handle the temperature. If your car is running an automatic, a large aftermarket trans cooler is essential. It is best to keep the trans temperature less than 225 degrees F, which may limit the number of laps you can run without a cool down. You should also consider running a power steering cooler. We've seen multiple power steering pump failures at big tracks due to cooked fluid.
