It's funny. Read through this thread, the people who put shit on these brakes have not used them. Everyone who has used them says they are good, including some really harsh use like rallies and racing. Pretty simple odds.
I always run the supplied pads in mine, I got the kit from Just Jap and they had a choice of street, sport or race pads. I run the race pads on the race car, and sport in rallies or on the street. No problems at all and I still haven't had to replace rotors (I have replaced pads a few times).
