I've been running these tires for about 1 year of autocross and some occasional street use to work.
These fair well with heat, I've only had them become greasy once on a 100 degree day using two drivers.
These like a bit of tire pressure for me, 38 cold, 42 hot. I'm running a 255/40r17 on a 17x9. Anything less and they roll too heavily. This may be due to my vehicles weight.
Damp traction is fine, but any standing water and these are hilarious. My STi slides around during normal speeds and turns once it is extremely damp. I avoid driving in the wet at all costs.
These are the best street class autocross tire hands down.
