Shane from what I picked up from reading reviews they're meant to be close to rcomp performance...would be good if someone whose used them in a full racing environment could confirm.
Rich I honestly don't mean to be rude, but please ring any tyre shop or john or wworld and I can guarantee you that they'll sort you out with the right information...
Please read the first post, was clear about what this thread is about, trying to keep it based on factual usage experience and performance rather than a debate of where and who supplies the tyre or who's the best tyre fitter.
Any of the suppliers just mentioned will be your best source of info
