I currently have Star Specs on my car for autocross and performed great at the one event I have run on them, so far. I had plenty of grip, especially considering they were being scrubbed in at the event. They held up very well even, with little noticeable wear after 13 runs (3 drivers) on a very grippy/abrasive concrete surface.

Last year I had Bridgestone RE-01R (the previous version of the RE-11Rs) and they worked well too, the RE-11Rs are supposed to be even better, so might be worth considering. About half of the events I ran last year were in the rain (unfortunately) and the Bridgestone's did very well for grip in the rain.
