I get about 15-17k from my front tyres. A fair bit more from the rears. Using Conti SC5s all round and although I never nail it from a standstill - I don't see the point in doing that - I can take off pretty briskly and hoon it through 1st and 2nd without any dramas. I've never had any breaking of traction once on the move in the dry (or even in the wet that I can recall) unless I shift particularly brutally from 1st to 2nd. It's just not a powerful enough engine for those short of shenanigans really. It's a great chassis, very balanced. Obviously you will have limitations because of what it is, but for what it is, it drives brilliantly IMHO.
Rybo come to the RR and I'll show you what it can do if you like (if that's not too far into the future of course)
