They have lots of different compounds- their pure race compounds are very common in pro racing, even NASCAR. I like their "Z-rated" compound, which is available around here at Autozone, I used to use these pads on my E30 325is track car, until they stopped selling them!! The pads last a LONG time, stop very well, and are not harsh to rotors or wheels. I never had a problem with them not working when cold. I put a set of them on my F350 Dually farm truck/tow rig about a year ago, and they work great.
