Wilwood 170-15717 Big Brake Dynamic Lug Drive Rotor Hat

The Wilwood 170-15717 is a high-performance Big Brake Dynamic Lug Drive rotor hat that revolutionizes brake rotor mounting with an innovative bolt-free attachment system. This advanced design allows the rotor to move independently of the hat during thermal expansion and contraction, eliminating thermally-generated stress at the mounting points for superior performance and longevity.

Key Features:

• Dynamic Lug Drive system eliminates traditional rotor mounting bolts
• Allows independent rotor movement during heat cycles to prevent thermal stress
• Spring-loaded replaceable stainless steel inserts protect aluminum hat from wear
• Single large snap-ring retention system for quick assembly and installation
• Maintains flatter, truer-running rotors throughout operation
• Eliminates pad knock-back and rotor drag issues
• Prevents hat distortion from thermal expansion and contraction
• No torquing or safety wiring of rotor bolts required
• Resolves bolt hole alignment problems during rotor replacement
• Precision-engineered lightweight aluminum construction

This innovative hat design delivers consistent brake response and pedal feel by eliminating all thermal distortion problems associated with conventional bolt-on rotor systems. The Dynamic Lug Drive system represents a significant advancement in brake rotor mounting technology for serious performance applications.
