I drive a heavily modified Porsche 951 making around 450 hp and 450 ft-lbs. The torque comes in quick and hard, it takes a really sticky tire to not turn to smoke in 1st and 2nd gear. These tires are the best I've ever had on this car, I'm running the 265/35/18 on a 10 wide wheel and its a little small, my next purchase will be 295/30/18's of the same tire. These things let me put my power to the ground, but they also let my car handle like a Porsche. I'm sitting on some pretty aggressive coil over suspension all around with huge sway bars and solid mounts everywhere. The car was built to rip corners, and these tires hold like glue at 100+ mph turns. I've got huge 4 pot brembo brakes grabbing 14 rotors on the car, with some pretty aggressive pagid pads. Its enough brake force to lock up most tires at 100 mph at max pedal effort, but these tires are the best non slicks I've ever used as far as having the grip to let me stop quickly. They handle wet weather great too, but I have to warn people these are a true summer tire and are downright dangerous in near freezing temps. I can't comment on the ride quality of these tires due to the aforementioned suspension, nor on the sound of them because I can't hear anything over my 4 open turbo-back exhaust. Tread life isn't incredible but I'm hard on these tires, sliding them around and spinning them fairly often. Also, its an incredibly soft performance tire so I wasn't expecting amazing life out of them. I said to myself if I got 10k miles on the street out of them I would be happy, and so far I'm at 15k and I think I can make it to 20k. When my current set of 4 is toast, I will definitely be buying another, slightly wider set. Great tires!
