Product Details
Centric’s C-TEK Standard Cross-Drilled Disc Brake Rotors line focuses on direct-fit replacement rotors with a drilled finish for drivers who want a functional upgrade over a plain iron disc. This rotor uses a floating disc mounting design, a vented body, and straight vanes to support consistent rear braking performance on Porsche 718 Boxster and Porsche 718 Cayman models, as well as earlier Boxster and Cayman rear brake applications. The 228.37047 rotor is engineered around the listed OE-style dimensions, including the 299 mm outside diameter and 20 mm nominal thickness, for a precise rear brake service replacement.
This part cross-references Raybestos Brakes (e.g., 980625R) for the same application.
Common Uses
- Rear brake rotor replacement for worn or scored Porsche rotors
- Correction for brake pulsation caused by rotor thickness variation
- Service replacement for iron disc brake rotor applications on Porsche Boxster and Cayman models
