I had a set of Continental ExtremeContact Sport (Max Performance Summer) Tires mounted to my second set of wheels and switched them out recently. So far I am very happy with their performance on the street. NOTICEABLY better ride quality over the stock Cup 2's and a slight reduction in road noise. The car no longer tracks with cracks/seams in the road and still responds very well. I haven't "gotten on it" very much as the tires are still wearing in however I do not expect them to hook as well as the Cup 2's for obvious reasons. So far VERY happy with my decision to go with Continental for street use. TireRack link below:

I had these on my Z06 that I sold before picking up my ZR1. I was also very happy with them. I plan to switch to them as well on my Z when the cups get about 4K on them. You didn't mention it, but they're not run flats, though that wasn't a huge deal for me.

Run them on my Z also. Good overall performance!

Looks like a good grocery store tire. Its narrower than the super spors and not as grippy.
