The Wilwood Dynamic Bobbin Mount rotor hat uses a bobbin-style mounting system that lets rotors move independently of the hat as they heat and cool, removing thermally generated stress from attachment points. This keeps rotors flatter and truer, improves brake response and pedal feel, and prevents pad knock-back and rotor drag. The hats provide a reliable, low-stress interface for two-piece rotor assemblies.
