I agree with S-03s, I have installed a few sets on cars and the customers have nothing but good things to say. Parada Spec-IIs are also nice.

I have a set of Sumitomo HTRZIIs on my ride now with less that 700 miles and they are some sticky shit =] I have been pushing them pretty far at speeds in excess of 100 mph on highway turns and have yet to have them break on me. Only down side is they wear pretty quickly from what I have seen on other cars, but their price is reasonable for a Z rated tire.
