18 versus 17 inch wheels. Is it all about side wall?

As I said, three of the local PCA racers have done it so far (911SC, Carrera, 951), and more have plans. Fitment on SC and Carrera: big t-bars, relocate right rear oil lines, shave or roll fenders, pull fenders if necessary. Basically the same stuff as fitting a 275.
But you guys are probably better off sticking with the large diameter 275s
