The Wilwood GT Dynamic lug-drive rotor hat uses a new rotor mounting system that eliminates traditional rotor bolts and lets the rotor move independently as it heats and cools. By removing thermally generated stress from attachment points, rotors run flatter and truer, brake response and pedal feel stay consistent, and issues like pad knock-back, rotor drag and bolt-alignment problems are avoided.
