Product Details

The Wilwood 300-12258 Rotor Bobbin is a precision brake hardware component designed for use with Wilwood's Aluminum Dynamic Hats in C/CSiC (Carbon/Silicon Carbide) rotor applications. These bobbins are a critical element of the dynamic bobbin-drive rotor mounting system, allowing the rotor to float independently of the hat as it expands and contracts through thermal cycles.

Key Features:

  • Stainless steel alloy construction for maximum abrasion resistance and long service life
  • Designed specifically for use with Wilwood Aluminum Dynamic Hats
  • Compatible with C/CSiC (Carbon-Ceramic) rotor applications
  • Spring-loaded bobbin assembly retains the rotor in the hat without conventional fixed-mount hardware
  • Allows rotors to move independently through heat cycles, eliminating thermally generated stress at attachment points
  • Helps rotors run flatter and truer for improved brake performance and longevity

Wilwood's dynamic bobbin mounting system is engineered for high-performance and racing applications where extreme thermal loads demand a floating rotor design. Replacing worn or damaged bobbins ensures the rotor retains its ability to float freely, protecting both the rotor and aluminum hat from stress cracking and distortion.

Great price for the item. Both internet and phone conversations were quick and knowledgeable.
