Replacement rings refresh the wear surface of a two-piece rotor assembly while the existing aluminum hats and mounting hardware stay on the car. That is the economics of a two-piece rotor: when the friction surface reaches its wear limit you replace only the consumable ring rather than the whole assembly.

The slotted face vents gas and clears pad debris so the pad keeps a clean bite through repeated heavy stops. Because these rings are cataloged by dimension, four numbers decide whether they fit: diameter, thickness, pin hole count and annulus. All four have to match the hats already on the car.

Fitment

These rings are cataloged by dimension rather than by vehicle. Match diameter, thickness, pin hole count, and annulus to your existing hats before ordering.
