I hear that wheel gap is a big thing in Mini circles?
My new autocross setup. Nankang CR-S 225/45-15 front. Yokohama A052 205/50-15 rear. Neither Yokohamas nor Bridgestone 225/50-15s would fit the front with legal offset, but the Nankangs do. I am significantly quicker on this setup than on RT660 in 215/45-16. Over 1s per run. Once I get the hang of driving on these, maybe 2s. Modified SSRs.
