I am wanting to autocross after joining the local S2000 club. It is really hard on brakes and want suggestions on the best performance pads and rotors.

I'd normally move it to S2000 Talk, but I think you'll get a more targetted response in Competition and racing.

 

Don't change the rotors. You won't like the class you end up in. Besides, the OEM rotors are awesome. Avoid the cobalt junk for a while until they get their suppliers ironed out again.

Pads are an open question. OEM pads will be fine for quite a while. Autocross really isn't very hard on brakes. You should be carrying as much speed into the corners as you can, anyway.

 

just bleed your brakes and you'll be fine

first mod should be tires if thats in your budget

 

Cobalt junk? Suppliers haven't changed. It's Centric; same now as it always has been. It's possible that they had a bad manufacturing run but your sample is too small to be statistically significant though.
