I bought these tires for the sole purpose of autocross. I run them only at events and whenever I go to the Tail of the Dragon. They've seen 30-40 autocross runs varying in times from 35-70 second long courses. The entirety of the miles on them has been from driving to the Dragon and to the events. I'll put them on the day before an event or Dragon run, drive and do my runs, and the next day they are generally off and back in my room to wait it out. Over half to 2/3 of the cars I've seen running in ST classes at autocross are running Star Specs. They are a great tire and I've never once heard of anyone complain about them. Yes the tread life on them is less than satisfactory, but nine times out of ten the type of person buying these tires dosn't buy them for the tread ware, but for the performance. For that reason I only run them at events to make them last longs and save me money, I am a college student after all. The grip, responsiveness and the inspired confidence from these tires is outstanding. This is the second car I've run Star Specs on, the first being a 1995 Integra LS Coupe also for autocross. I'll continue to buy them until I can afford to upgrade to sticker R-Comps. Having never driven this car at a stock ride height as I bought it lowered I can't compare ride comfort for the tire, but I can imagine it's diminished as well as the increased noise level, but again you don't buy these tires for the creature comforts. You buy them for the raw performance you will get from them. Going from Toyo Proxes All Seasons with no tread to Star Specs for autocross was a night and day difference. I've been able to drive the car faster and harder and decrease times by up to 5-6 seconds which any autocrossers reading this will know is a looooooottttt of time. They inspire confidence in my driving ability and in what my car is capable of. Currently leading the STF class in region on Star Specs and I recommend them to any and all.
