Performance Friction replacement rotor rings for the company's two-piece floating brake rotors are intended for refreshing the rotors once the original rings have worn out. Since the center hat and spiral clip can be re-used, you just need the cast replacement rings.
As with the original rotor, the PFC replacement disc is made from a proprietary cast iron; the directional multi-vane design maximizes cooling.
These rings are suitable ONLY for PFC rotors, and ONLY for the 2018-2021 six-piston STI Brembo replacement rotors. They are NOT going to fit other manufacturers' two-piece rotors, nor will they fit PFC rotors for other applications.
