Info

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.

Spring-loaded, replaceable stainless steel inserts in each lug-drive slot protect the aluminum hat from wear that would otherwise be caused by loading of the stainless steel rotor against the hat when brake torque is applied. A large, single snap-ring retains the rotor in the hat, making assembly and installation literally a snap. There is no longer any need to torque or safety wire rotor mounting bolts. The already lightweight stainless alloy discs are additionally drilled to remove all unnecessary rotating weight from the driveline.
