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.
