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.

Wilwood lug drive dynamic hats have a design that allows you to incorporate a new rotor mounting system that eliminates the rotor bolts and allows the rotors to move independently of the hats. They help rotors stay flat and run true, while keeping braking response and pedal feel consistent. Pad knock-back and rotor drag are both eliminated as well. These hats cause all problems associated with thermal distortion to be eliminated, including bolt hole alignment issues when trying to reinstall new rotors on previously used hats.
