Wilwood 170-16011 Big Brake Dynamic Lug Drive Hat

The Wilwood Big Brake Dynamic Lug Drive hat features an innovative rotor mounting system that revolutionizes brake performance and maintenance. Unlike traditional bolt-on designs, this system eliminates rotor mounting bolts entirely, allowing rotors to move independently of the hat as they expand and contract through heat cycles.

Key Features:

• Bolt-free Dynamic Lug Drive system eliminates all thermally generated stress at rotor attachment points
• Rotors stay flatter and run truer throughout heat cycles for consistent brake response and pedal feel
• Eliminates pad knock back, rotor drag, and thermal distortion issues
• Spring-loaded replaceable stainless steel inserts in each lug-drive slot protect aluminum hat from wear
• Large single snap-ring retention system for quick rotor installation and removal
• No torquing or safety wiring required for rotor installation
• Lightweight design reduces rotating mass on the driveline
• Eliminates bolt hole alignment problems when installing new rotors on previously used hats

This advanced hat design removes the frustrations of traditional rotor mounting while delivering superior performance. The protected lug-drive slots handle brake torque loading without damaging the aluminum hat, and the snap-ring retention makes rotor changes fast and simple. Compatible with Wilwood's drilled stainless alloy rotors for maximum weight savings and thermal management.
