I am going to buy some Rota Slipstreams for autocross. What tyre size is being used by most people? It does seem that larger fronts can be used how about the rears?

I was thinking about doing the exact same thing for autocross and switching to R888's... also interested in the exact sizes of rim and tire I should go for

I run 205/245 RA1s on 15/16 rotas. Some people run 225/245 on the 15/16 combo.
