Description
Wilwood Hat-Dynamic Drag 1.96in Offset 11/16in Studs - 8 on 7.00in
Wilwood's new Lug Drive Dynamic hats incorporate a new rotor mounting system that eliminates the rotor bolts and allows the rotors to move independently of the hats as they expand and contract through heat cycles. All thermally generated stress is removed from the rotor attachment points. The rotors stay flatter and run truer. Brake response and pedal feel remain consistent. Pad knock back and rotor drag are eliminated. The hats are no longer distorted by stresses generated by thermal expansion and shrinkage of the rotors. All problems associated with thermal distortion, including bolt hole alignment issues when trying to re-install new rotors on a previously used hat, are eliminated.
