I have been track driving (FWD and RWD) since 1998 and it took me about 3-4 track events to even figure out this car and get it sliding around. I will wear these tires out and get to the point of passing the adhesion limits (just about there) and then eventually move up to street tires on 18" wheels (I will never go to R-compound, unless racing...been there and done that. R compound is not needed for HPDE).
