PARAGON Rotor Rings – 343 x 28mm, PCD 216, 12-Bolt – Replaces Alcon DIV2175X521
Paragon Performance replacement rotor rings for 2-piece floating brake rotors measuring 343 x 28mm on a 216mm PCD, with 12 round mountings (6.4mm). They replace Alcon DIV2175X521. 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 (216mm), mountings (12 round holes, 6.4mm) and max pad depth (54mm) match your assembly before ordering. Installation by a professional is recommended.
