Cosmos, learn to drive your car while it’s in stock condition. Take a set of extra brake pads just in case. Once you’ve learned to drive your car on the track, by taking a few schools, get a good set of summer max performance tires. Suspension components should be the last modifications, unless they’re currently worn out. Modifying a car for the track is not as important as the learning process. I’ve seen plenty of students driving with completely stock cars, out perform students in highly modified cars. The driver is the most important modification, when it comes to track time. More track time with proper instruction will make you a smoother driver. The smoother you are, the faster you are. When you’re on the track, it’s a driving school, not a race.
