Am thinking of getting a spare set of 18" wheels mainly for track use since good R tyres are more accessible in 18" and smaller diameter wheels should give better acceleration off the line. But given the huge 380mm carbon disc now fitted at the front of Stradales, I'm worried it can only fit 19" and you're pretty much stuck with only 2 tyre models: Michellin Pilot Sport Cup and the Pirelli P-Zero Corsa, which apparently aren't quite as good as the semi-slicks like the Yokohama Advan A048, Dulop D01J etc... So, has any track race experts here tried fitting 18" wheels on a 360 CS? If it does fit, what make rims are best for it (BBS? Is that the lightest?) and what semi-slick tyres work best with the Ferrari? Thanks for the help!
