[Shotimes] Front Rotor Warping

[James White]

Weither it be the cheap chinese or the premium American cross-drilled
rotors, I have great luck in having them cryo treated.

A set of cryo treated (think made in Canada from Joe Scott) went well over
120k.  Actually replaced them because they wore too thin.

'95  5 SPEED   242k lots of mods
"double clutch"  it's good for both you and your SHO
