people don't realize its all just a matchmaking with your driving and the temp range of pads. I use Hawk, but really if you dig you should be able to find this info on any popular brake pad manufacturer. check out this link.

If you are not braking in the pads best temp range, they are not going to work for what you are doing (cold or hot... you want to match it with where you are at). Also, not sure about all brands but hawk says that their street pads (hps/hps 5.0) and their race pads have a similar enough base compound that you don't have to turn or sand rotors when switching out. Huge for the guys like me that will change out the pads for the weekend at the track (only a few times a year) and go back to a streetable pad for normal driving.
