Wilwood 170-16199 Big Brake Dynamic Lug Drive Rotor Hat

The Wilwood 170-16199 is a high-performance disc brake rotor hat featuring the innovative Big Brake Dynamic Lug Drive system. This advanced rotor mounting system eliminates traditional rotor bolts and allows the rotors to move independently of the hats as they expand and contract through heat cycles, removing all thermally generated stress from the rotor attachment points.

Key Features:

• Dynamic Lug Drive system eliminates rotor bolts for stress-free thermal expansion
• Rotors stay flatter and run truer throughout heat cycles
• Maintains consistent brake response and pedal feel
• Eliminates pad knock back and rotor drag
• Spring-loaded stainless steel inserts protect aluminum hat from wear
• Single snap-ring retention system for quick assembly and installation
• No torquing or safety wiring of rotor bolts required
• Eliminates bolt hole alignment issues during rotor replacement

Performance Benefits:

• Prevents hat distortion from thermal rotor stress
• Reduces rotating weight for improved driveline efficiency
• Simplifies rotor installation and maintenance
• Extends component life by eliminating thermal distortion problems

The replaceable stainless steel inserts in each lug-drive slot are strategically positioned to protect the aluminum hat from wear caused by brake torque loading. This engineering innovation solves common problems associated with traditional rotor mounting systems, including thermal distortion and difficult rotor reinstallation on used hats.
