The Wilwood Dynamic Lug Drive rotor hat uses a new rotor mounting system that removes conventional rotor bolts and lets the rotor move independently of the hat as it heats and cools. That separation removes thermally generated stress from attachment points so rotors stay flatter and run truer. The design improves pedal feel consistency while eliminating pad knockback and rotor drag associated with thermal distortion.
