In Reply to: Brake Pads for Track Use Questions posted by BB on May 15, 2001 at 14:58:14:
I will be doing a track day in my M3 soon, and I'm trying to decide which brake pads to use. I once did a track day in an MR2 Turbo, starting with brand new stock pads, and after three 20-minute sessions they were worn down to the backing plates. So I learned that stock Toyota pads don't hold up to the heat of track use. Since then I've used Hawk racing pads on my road race and track cars. Usually Hawk blue compound, but sometimes black compound on one end if I wanted to change the effective brake bias. So, here are my questions:
1. How well do stock M3 pads hold up to track use? (I recently bought the car with 46K miles on it, but the pads look new. They also squeal like racing pads do.)
2. Are the combination track/street pads like the Hawk HP+ really good for both street and track and autox, or are they too much of a compromise to do anything really well? (I don't mind swapping brake pads for track days if I'll get significantly better performance from them.)
3. I suppose I should get a spare set of rotors, too, right? Where can I get a good price on them? (I have cracked rotors on RX7s and Miatas that I raced, and don't want to get stuck without spares.)
4. Anyone ever cracked an M3 rotor from track use?
BTW, the track will be Summit Point, which is pretty tough on brakes.
