Wilwood Lug Drive Dynamic Drag Rotor Hat Offset

Wilwood Lug Drive Dynamic Drag rotor hats are lightweight aluminum brake rotor hats made for drag racing and other demanding motorsports use. They use a lug drive, dynamic mount design. This design removes the rotor mounting bolts and lets the rotor move independently of the hat. Each hat is offered in a range of offsets for different applications.

Key Features:

• Dynamic lug mount design: The rotor floats in the hat as it expands and contracts through heat cycles. This removes thermally generated stress from the rotor attachment points.
• Lightweight aluminum construction: Machined from aluminum for strength with low unsprung and rotating weight.
• Floating T-nuts: Wilwood T-nuts float within the hat for true dynamic mounting of compatible through-hole rotors.
• Replaceable stainless steel inserts: Spring-loaded inserts in each lug-drive slot protect the aluminum hat from wear caused by rotor loading under brake torque.
• Snap-ring rotor retention: A single large snap ring holds the rotor in the hat. This makes assembly and installation simple, and rotor mounting bolts don't need to be torqued or safety wired.
• Consistent braking performance: Rotors stay flatter and run truer. Pedal feel stays consistent, and pad knock-back and rotor drag are reduced.

Wilwood is a well-known maker of high-performance brake systems, and these hats are built for racers who want weight savings, durability and repeatable braking. Because the hats avoid thermal distortion, bolt hole alignment problems are eliminated when new rotors are installed on a previously used hat.
