Well, I've never run the Star Specs but I remember looking at them closely. People were saying they were getting ~10k miles on them maybe 15 at best if I can recall. If you want the most performance (track / autox any?) , Hankook RS-3's are probably what you want, but if you're doing Auto X and Track events, don't expect to get more than 8k miles out of some RS3's
