I was reading up on the compounds and whatnot, those 285/645's are "GT-O", which is supposedly slower rubber than an R6, FYI (whereas their "GT-R" compound is faster, but no discontinued ones of that in the right size). Apparently GT-O was a special compound they did for the high banked oval courses like Daytona. But still, it's cheap, and it's not like I really care about my lap times. My first set of slicks is just going to be about learning whether I can handle driving on slicks or not
