<E36 M3> Preventing Rotor Warpage

["Peter Stuhr" <peterstuhr@xxxxxxxxxxx>]

Preventing your M3 rotors from warping...

Replace the stock front rotors with the Euro rotors. You can get them 
for the same price as the stock U.S. rotors and the aluminum hubs help 
dissipate heat much better. Also, after pulling into the pits after a 
long run make sure you don't come to a complete stop with the brakes or 
emergency brake. Let the car roll a few feet forward without the brakes 
on and then stop the car with the clutch only.

But even more importantly - for the next 5-10 minutes after pulling into 
the pits, release the clutch about every minute and the car roll 
forward/backward about a foot. This allows the rotor to cool evenly. The 
area of the rotor directly under the caliper/pads will cool much more 
slowly than the rest of the rotor. By moving the rotor every few minutes 
it will cool evenly. 

Rotor warpage is not caused by the heat - it's caused by uneven cooling.
