What is your experience with your pads or rotors on the track? One of the tracks we use has a 130-60mph brake area that just tears up the brakes. I have the pads/rotors that come with this kit. I just need to decide what pads I would use since I won't have time to test these out before the next track day. We get a minimum of 4 20 minute sessions. The question is. "how much rotor wear will the original pads create?". For example, when I replace the pads on track day, am I going to have to replace the rotors also or are the pads soft enough so that there isn't too much damage to the rotor? In that case, should I stay with the factory pads or can I use a harder pad to try and get a longer life. For that matter, how many minutes am I going to get of the pads/rotors that came with the kit? Any help in this area would be greatly appreciated.
