Wilwood 170-17010 Big Brake Dynamic Lug Drive Disc Brake Rotor Hat

The Wilwood 170-17010 is a Big Brake Dynamic Lug Drive Rotor Hat featuring Wilwood's advanced bolt-free rotor mounting system. Unlike traditional fixed-mount designs, this hat allows the rotor to move independently as it expands and contracts through heat cycles, completely eliminating thermally generated stress at all rotor attachment points. The result is a rotor that stays flatter, runs truer, and delivers more consistent brake response and pedal feel throughout demanding use.

Key Features:

• Dynamic Lug Drive mounting system — eliminates rotor bolts entirely for a cleaner, stress-free rotor attachment
• Thermal expansion management — rotor floats independently of the hat, preventing distortion and bolt-hole misalignment during rotor replacement
• Eliminates pad knock-back and rotor drag — consistent pedal feel is maintained even after repeated heat cycles
• Spring-loaded, replaceable stainless steel inserts in each lug-drive slot protect the aluminum hat from wear caused by brake torque loading
• Single large snap-ring rotor retention — simplifies assembly and installation without the need to torque or safety-wire rotor mounting bolts
• Drilled stainless alloy discs — unnecessary rotating weight is removed for improved driveline efficiency
• Precision-machined from premium-grade aluminum alloy for high strength and low unsprung weight

The Wilwood 170-17010 Dynamic Lug Drive Rotor Hat is engineered for high-performance street and competition brake systems where thermal stress management, rotor longevity, and consistent braking performance are critical priorities.
