Wilwood 170-13170 Dynamic Bobbin Mount Brake Rotor Hat

The Wilwood 170-13170 Dynamic Bobbin Mount Brake Rotor Hat features an innovative mounting system designed to eliminate thermal distortion issues common with traditional rotor hats. This advanced design allows the brake rotor to move independently of the hat as it expands and contracts during heat cycles, removing all thermally generated stress from the attachment points.

Key Features:

• Dynamic bobbin mount system allows independent rotor movement during thermal expansion
• 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 contraction
• Precision-engineered for high-performance braking applications

This rotor hat is ideal for racing and high-performance street applications where consistent braking performance under extreme thermal conditions is critical. The bobbin mount technology represents a significant advancement in brake system design, addressing problems that have long plagued fixed-mount rotor systems.
