I used to compete in what is best described as time attack with my car. Street rubber as well as Hoosiers. At the time my car was lowered to the point it was on the bump stops under heavy braking. The camber arms (Ground Control) would hit the rear sway bar at traction limits in the corners. So don't go too low if your racing! Mostly higher speed tracks with old paved surfaces. Slick, rough, etc. Best front camber was anywhere from -1.8 to -2.2, 38 to 39 psi hot. Rear was best from -1.5 to -1.8, 36 to 37 psi hot. My car liked rear toe in, anywhere from 1/8 to 1/4. 0 toe front. Get as much rubber on the front as possible. It makes a huge difference in braking. Cornering, too, but not as much as you suspect. The sweet spot is magic when you hit it. But that spot moves around depending on the surface, speed, temperature, etc. Have fun and learn to use all the tools at your disposal. (tire temp probe, calibrated air pressure gauge) I had good success but believe if I'd raised my car up a bit it would have been better.
