It depends a lot on how fast you are. Variance in corner speed changes your shift points so what works for one may not work for you.
-1+2 is usually a good starting point but odds are if you keep racing you'll end up with a collection of sprockets. Right now i have -1 and -2 fronts and +1, +2, +3 and +4 rears.
