1. Stock power. It’ll take you quite some time before you use 100% power/torque. It’s best to learn how to drive on track with a low power car so you develop smoothness and maximizing corner speed. A stock F8x is a high power car, it does not need more power!
2. Camber plates. Without them you’ll destroy your new tires quickly. It’ll also allow you to get the most grip out of your tires. If your car is primarily street driven, run F camber at neg 2.5-2.75 deg, R camber at neg 1.8-2.0 deg. Camber plates pay for themselves quickly by extending tire life.
3. Track pads and high temp brake fluid. Brakes and tires are the two major safety items you don’t skimp on when tracking your car. I’d recommend PFC 11 but everyone has different preferences when it comes to brake pads. PFC, Hawk, Cobalt, Carbotech to name a few good choices. Brake fluid is a tricky one because BMW DSC and ABS systems are designed for low viscosity (LV) fluid but high temp race brake fluid is normal viscosity (NV) fluid. At track temps, NV fluid thins down to close to LV fluid properties; however, at street temps there are big differences between LV and NV properties. Most of the time NV works well enough on the street but it could create an ABS or DSC issue. I’d start with a higher performing LV brake fluid like Motul LV. If you encounter brake fade, upgrade to a race brake fluid. Plenty are available.
4. Seat time, seat time and more seat time. Driver mod is the biggest one to maximize. Upgrading performance parts on the car doesn’t help if you haven’t developed the skills to exploit them.
