[Shotimes] Front Rotor Warping

[Jim and Debbie Leyden]

Oops... Forgot... New Timken wheel bearings and it was all asssembled at
FPS.  The original rotors were NAPA Lifetime.

What brand were the orginal rotors?

The 96 rotors will warp under heavy braking and fairly easily.

How are your wheel bearings?
