5 Cheap Ways to Make Your Car Go Faster at the Track



If you’re taking your car to the track, you know the term “cheap” is relative.

Nothing is really inexpensive when it comes to racing (or even just lapping), but one need not spend tens of thousands of dollars on ultra-expensive car parts to make a car track-ready. Here are some simple and reasonably affordable mods that will help you lower your lap times.



Better Tires



Most experts will tell you that when it comes to improving your car’s track performance, tires provide the single biggest bang for your buck. By using a set of dedicated racing tires, you can choose a tire optimized for performance on the track and not worry about wearing them down or puncturing them with a nail during your daily commute. Good tires need not be expensive; do your research and you’ll find plenty of tires that offer excellent grip at a much more moderate price than you might expect.

Racing Brake Pads



It might seem counterintuitive to the uninitiated, but the faster you can stop, the faster you can go. Better brakes resist fading from repeated use and allow you to stay on the power longer before you brake for a curve. Racing brake pads come in different compounds; some work well only when really hot, while others are more tolerant to broader temperature ranges. Don’t just buy the most aggressive pads you can get — they may provide little stopping power when cold. Instead, do some research and then shop for the best price on the type of pad you need.

High-temperature Brake Fluid



One you start to really use your brakes to their maximum potential, you’re going to start generating very high brake temperatures — high enough, perhaps, to boil the fluid in the lines. Boiling fluid creates air bubbles, which, unlike the fluid itself, can be compressed — and when that happens, thump, your brake pedal goes to the floor (and your car, perhaps, goes into the tire wall). Some brake fluids absorb moisture over time, which lowers the boiling point, so at the very least, you should change your brake fluid before you go to the track, but if you want to do it right, replace your original-equipment fluid with DOT 4 or DOT 5.1 fluid, and be sure to pay attention to the fluid-change intervals for the new formulation.

Lightweight Wheels



Most people put new wheels on their car to improve its look, but if you’re going racing, you want a wheel that will improve performance — and that means light weight. A lighter wheel reduces unsprung mass (the part of the car’s weight that is not supported by the suspension), which allows the wheel to respond more quickly to bumps and other terrain changes, improving the car’s grip. Lightweight rims need not be fancy or expensive; they just need to be light! You can save money by buying used, but be sure the wheels have not been damaged or abused.

Adjustable Shock Absorbers



Adjustable shock absorbers (also known as dampers) allow the owner to set the compression and rebound rate — basically, how much the shock resists the upward and downward travel of the wheel. (Don’t confuse them with shocks that allow adjustment of ride height. If you search for the term “adjustable dampers” you’ll get better results.) Some shocks allow individual adjustment of compression and rebound, others tie them together; either way, they allow you to fine-tune the car’s handling and achieve the perfect handling balance or to compensate for conditions at different tracks. Adjustable shocks can be found as stand-alone units or as part of a coil-over kit; the latter is a bigger investment but one that is worthwhile.

Gotta comment on this article. While it's written for a broad automotive application, it ignored parts like front and rear swaybars, which will dramatically change a car from an understeering pig, to something more neutral. Also, buying new tires with a lot of tread depth can mean the tires get destroyed by excessive tread distortion and heat, while not helping the handling much. Brake pads, brake fluid and shocks make sense, but GOOD lightweight wheels are anything but cheap!
