Good brake pads #1.
I add a little negative camber before I go to the track, the inside bire is great on the track but sucks for tire milage.
Also purge your brake fluid, add all new. Doesn't really matter what kind, it will probably look like iced tea when you are done anyway. If it doesn't boil, then there isn't much since in paying for the really good stuff.
PLay with you tire pressure, do you know how to use chalk on the sidewalls?
