Description
Paragon Performance Rotor Rings 355mm x 28mm — 229mm PCD — D50
Application: 355mm x 28mm rotor rings with 229mm P.C.D. and 12x9.5mm mounting
Part Number: PRR.8010.355.2530.280.22900.12.01
Design Code: D50
Paragon Performance rotor rings feature directional ventilation vanes engineered for maximum airflow and thermal management under sustained high-load braking. The vane geometry accelerates heat extraction from the friction ring, keeping brake temperatures in check lap after lap and reducing the risk of thermal fade during extended track sessions.
Manufactured from CM-250 premium cast iron and finished using CBN (Cubic Boron Nitride) precision machining, each rotor ring delivers an exceptionally consistent friction surface. CBN machining produces tighter dimensional tolerances than conventional grinding, ensuring even pad contact and predictable, linear braking feel from the first lap.
The floating two-piece design decouples the friction ring from the aluminium hat, allowing the ring to expand thermally without inducing hat distortion or disc warping. The slotted face pattern continuously deglazes the pad surface, expels gases and debris, and maintains consistent bite — critical for drivers who demand repeatable braking performance across varying conditions.
The lightweight aluminium hat is CNC-machined to precise tolerances and designed for direct bolt-on fitment. With 12x9.5mm mounting and a 229mm P.C.D., these rings are a straightforward replacement for compatible D50 brake systems with no modification required.
