My car is an '09 Z06 with full bolt ons & a tune. It's pushing around 620hp to the motor, and these tires never break loose. The vette is also my daily driver, so the great tread wear on these are even nicer. I've driven in the rain a few times, and each time the traction has been great.
Dry traction is AMAZING. Much better than the run flats that came with it. Much nicer ride and quieter too. I would highly recommend these to anyone that wants a great performance tire, and doesn't want to pay an INSANE amount.
