I have these on a highly modified 1971 Nova. They have been through three autocross events and a road course event as well as serving daily driver duties. They tires provide excellent cornering stability and traction. It is pretty easy to overpower the rear tires, but they are very predicable and controlable when you do apply too much power through the turns. They have decent ride and comfort for an extreme performance tire. Much better than I'd expect for a tire of this type. Wet traction is good, but hydroplaning is a problem in heavy rain at high speed. I keep it below 70 in these conditions. They are wearing like iron. In the road course event, the tires didn't marble like many of the other tire brands at the event. I will definitely buy these tires again.
