Didn't seem to have much rear end grip at all (compared to front & other people) but managed to pass a few elises and beemers though

I'm now wondering about a set of wheels with better wet tyres on (i.e. not R888's) just in case. Any thoughts on good wet tyres? just for track days, not road use...
