The Wilwood Dynamic Mount rotor hat uses a bobbin-based mounting system that lets the rotor move independently from the hat as it heats and cools, removing thermally generated stress from attachment points. That keeps rotors flatter and truer through temperature cycles, preserves consistent brake response and pedal feel, and helps eliminate pad knock back and rotor drag for steadier braking.
