Thanks for the valuable insight guys I really appreciate it. On a side note, disregarding weight is the optimum wheel diameter size for track cars 18"? Because I have noticed in nearly all the big sports car racing series they all seem to run 18" wheels. And I checked Michelins race tires and they only offer 18" race tires. Also every gt3 cup/R/RSR runs 18"s so if 18"s are optimal why?
