Wilwood 170-16102 Big Brake Dynamic Lug Drive Rotor Hat

The Wilwood 170-16102 is a high-performance disc brake rotor hat featuring Wilwood's innovative Big Brake Dynamic Lug Drive system. This advanced mounting system eliminates traditional rotor bolts and allows the rotor to move independently of the hat during thermal expansion and contraction, removing all thermally generated stress from the attachment points.

Key Features:

• Dynamic Lug Drive system eliminates rotor mounting bolts for independent rotor movement
• Reduces thermal stress at attachment points, keeping rotors flatter and running truer
• Spring-loaded replaceable stainless steel inserts protect aluminum hat from wear
• Single large snap-ring retention system for quick assembly and installation
• Eliminates pad knock back, rotor drag, and thermal distortion issues
• No torquing or safety wiring of rotor bolts required
• Resolves bolt hole alignment problems when installing new rotors on used hats
• Maintains consistent brake response and pedal feel through heat cycles

The Dynamic Lug Drive design features spring-loaded stainless steel inserts in each lug-drive slot that protect the lightweight aluminum hat from wear caused by brake torque loading. This innovative system eliminates all problems associated with thermal distortion while simplifying installation and maintenance.
