What are some good performance tires?

I like my Falken Ziex ZE-512s, they were $99 each in the stock size.

I have Sumitomo on the cobra and Dunlop Sport Sp9000 on the Z/28 and they suck compared to the sumi's.

Currently running BFG KDWS' and there is a definate improvement in ride quality with them compared to the stock Eagle ZR's, but I think my next set is going to be GY Eagle F1's.

I never thought I'd buy replacement GY's ever, since all their other tires are such garbage, but I've heard and read nothing but good things about the F1's.

Nitto's are Junk! Their DR's suck too!
