On 2 of the track days iv been on the wilwoods have coped pretty well with the Poly Q's, but twice i have had marshals come over and tell me that my disks are glowing bright red and theres sparks coming out under heavy braking. Now the brakes have only faded slightly on me at the end of a 15minute session, and i mean slightly faded, they still had enough stick to slow the car down but the noises out of them when im on the pedal are horrible, make me cringe, a heavy grinding sound and after attacking castle coombe my disks are slightly warped, they still work fine but you can see their warped when you spin them with the wheels off. They squeel when cold too, but that doesnt bother me. I know andy (fubar) had tiny hairline cracks in his disks after attacking cadwell park (IIRC).
Has anyone else experianced any problems like these with their wilwood setups?
