    I purchased these tires for my 2014 autocross and track days. I mounted them on some 17" lightweight racing rims used only for my racing events and couldn't be happier. I have a 98 Impreza wagon with the stock 2.2l, setup for autocross/street using Tein SS coilovers @ 5k, and Whiteline 22mm sway bars. They have amazing grip and I took overall 2nd place (by less than 0.1s) @ my 1st autocross event of the season which was drizzly/raining. The car was so planted & put in such good times, nobody could believe my car wasn't turbocharged. These tires have lasted a 300 mile road trip, the entire 2014 season of autocrossing with two drivers, and a track day. I am extremely pleased with them overall. I estimate they are good for at least another half a season. I have no idea if this is relevant, but after all my autocrossing with these tires, I now have a rear wheel bearing going out. I can only assume that the grip from these tires exacerbated wear and tear on my aging wheel bearings on my Subaru with 118k miles. Not sure if that's a compliment to the tires or not. On another note, these tires are all but unbearable for street use, but that's not why I bought them... I'm torn between sticking with this tire, or possibly trying something new when it's time to replace these tires next year.

    great tire on dry, ok in wet, have to be careful when autoxing as tires get greasy if they are overheated (which only takes a couple laps) I've gotten better grip with them going from 40 psi down to 34psi

    Dry traction very good and predictable. Wet more than adequate with tread depth greater than 5/32's. Other reviews of scary wet handling at limit reflect worn tread more than tire's abilities. At 140 Treadwear rating, you get about 7-10K miles before hitting the wear bars with aggressive driving. Get noisier as they wear. Very rarely do they squeal on hard cornering once they loose their new tread "squirm" factor. Keep the pressure up in the low 40's once warm and they will tolerate aggressive cornering very well without fading. Lower pressures will allow them to overheat with fall off.
