Although I do agree that 18" wheels may provide a SLIGHT performance advantage, I've got to point out that what goes on a race car can mean absolutely nothing for the equivalent road car. First, those 18" wheels on the ALMS GT car are 12" F and 13" R. Second, I don't know off the top of my head, but all of this may be dictated or engineered to meet some form or regulation or requirement by ALMS for this particular car.
For example, F1 cars are restricted to 15" wheels, does that mean we should all get smaller brakes and run 15" wheels too?
