Wilwood rotor/hat register rings, 2.86-inch diameter, are sold in a two-pack to center rotors on hats or hubs where register diameters differ. These rings secure proper concentricity between rotor and hub, improving running clearance and reducing vibration after installation. They are intended for use during brake upgrades or when adapting aftermarket rotors to existing hub hardware to ensure accurate alignment and smooth operation.
