Wilwood 170-16536 Big Brake Dynamic Lug Drive Disc Brake Rotor Hat

The Wilwood 170-16536 is a Big Brake Dynamic Lug Drive Rotor Hat featuring an innovative bolt-free rotor mounting system engineered to eliminate the thermal stress and distortion problems common with traditional rotor hat designs. By allowing the rotor to float and move independently of the hat through heat cycles, this lug drive system keeps rotors running flatter and truer for more consistent brake response and pedal feel.

Key Features:

• Bolt-free Dynamic Lug Drive mounting system — rotor expands and contracts freely, removing all thermally generated stress from attachment points
• Spring-loaded, replaceable stainless steel inserts in each lug-drive slot protect the aluminum hat from wear caused by rotor loading under brake torque
• Single large snap-ring rotor retention — simplifies assembly and installation, eliminating the need to torque or safety-wire rotor mounting bolts
• Eliminates pad knock-back and rotor drag for improved braking consistency and feel
• No bolt hole alignment issues when installing replacement rotors on a previously used hat
• Lightened stainless alloy disc — drilled to remove unnecessary rotating weight from the driveline
• Precision-machined from premium aluminum alloy for high strength and minimized unsprung weight

The Wilwood Dynamic Lug Drive rotor hat is an ideal upgrade for high-performance street and competition brake systems where thermal management, rotor longevity, and consistent pedal feel are critical. Sold individually.
