Wilwood 170-13160 Dynamic Bobbin Mount Brake Rotor Hat

The Wilwood 170-13160 Dynamic Bobbin Mount Rotor Hat features an innovative mounting system that eliminates thermal distortion problems found in conventional rotor attachments. This performance brake component allows the rotor to move independently of the hat as it expands and contracts during heat cycles, removing all thermally generated stress from the rotor attachment points.

Key Features:

• Dynamic bobbin mount design permits independent rotor movement during thermal expansion and contraction
• Eliminates thermal stress at rotor attachment points for flatter, truer-running rotors
• Maintains consistent brake response and pedal feel throughout heat cycles
• Prevents pad knock-back and rotor drag caused by thermal distortion
• Protects hat from distortion due to rotor thermal expansion and shrinkage
• Precision-engineered for racing and high-performance brake applications

This rotor hat is designed for use with Wilwood's bolt-together rotor systems, providing superior performance in demanding racing and track environments where consistent brake performance is critical.
