Wilwood 170-14911 Big Brake Dynamic Lug Drive Hat 8.80 Snap Ring 1.37 Offset

The Wilwood 170-14911 is a high-performance disc brake rotor hat featuring the innovative Big Brake Dynamic Lug Drive system. This advanced mounting design eliminates traditional rotor bolts and allows the rotor to move independently of the hat as it expands and contracts through heat cycles, removing all thermally generated stress from the rotor attachment points.

Key Features:

• 8.80-inch diameter with 1.37-inch offset for precise fitment
• Bolt-free Dynamic Lug Drive system eliminates rotor mounting hardware
• Single large snap-ring retention for quick, tool-free rotor installation
• Spring-loaded replaceable stainless steel inserts protect aluminum hat from wear
• Eliminates pad knock back, rotor drag, and thermal distortion issues
• Maintains consistent brake response and pedal feel through heat cycles
• No torquing or safety wiring of rotor bolts required
• Prevents bolt hole alignment problems during rotor replacement

By allowing independent thermal expansion, this rotor hat keeps rotors flatter and running truer while eliminating hat distortion caused by rotor stress. The stainless steel lug-drive slot inserts bear the braking torque loads, protecting the lightweight aluminum hat from wear. This design represents a significant advancement in brake system performance and serviceability for racing and high-performance applications.
