Steve,
I had been running the old bfg g-force kd 275/40/18's in the rear. They were not great, even for the street, and gave you zero warning at the limit.
I have heard good things about the dunlop direzza star spec so I am going to get those in a 265/35/18. The right side rubs a bit with a 275, and I want to take out some negative camber (necessary for clearance). tire wear was brutal, and lousy for drag strip launches. My car is mainly for street, otherwise I would look at teh Toyo r888. I have 480 rwhp and 441 ft lbs. to harness.

why do the cars with better power to weight and better tires keep posting slower times???
