I've heard nothing but good things said about the DZ03g's, Phil Morrison says they are even better than 888's but they are even more expensive
He also uses Michelin Pilot Cups on his GT3 but they only come with 4mm tread from new and are even more expensive

I'd love to beable to afford to try out a set of V70's, DZ03g's and the Michelin Pilot Cups but it's rather an expensive test that I can't afford.
