PARAGON Rotor Rings 300 x 25.4mm, PCD 158.8, 10-Bolt, 10mm Vane Gap

PARAGON Rotor Rings – 300 x 25.4mm, PCD 158.8, 10-Bolt, 10mm Vane Gap

Paragon Performance replacement rotor rings for 2-piece floating brake rotors measuring 300 x 25.4mm on a 158.8mm PCD, with 10 oval mountings (8 x 12mm). Each ring is cast from CM-250 high-carbon alloy iron with 48 directional vanes that pull air through the disc, so it runs up to 30% cooler than an OE rotor.

The rings are heat treated to relieve stress, then CBN machined for quick pad bedding. Lateral run-out is held within 0.03mm and balance within 2 g, which keeps judder down. The slotted face keeps the pad surface clean and helps in the wet. Sold as a left and right pair.

Note: Hat hardware is sold separately. Paragon recommends new hardware when replacing rings; its rotor assembly instructions give the torque specs. Confirm PCD (158.8mm), mountings (10 x 8 x 12mm oval) and max pad depth (50mm) match your assembly before ordering. Installation by a professional is recommended.
