Paragon Performance Replacement Rotor Rings – 355mm x 28mm, 233mm PCD (D50)

Designed as direct replacement rotor rings for high-performance 2-piece brake systems, these Paragon Performance 355mm x 28mm rotors with 233mm PCD (D50) deliver exceptional braking consistency, cooling, and durability for track and race use.

Manufactured from Paragon’s CM-250 high carbon alloy cast iron, each rotor ring is heat-treated to relieve stress and CBN-machined for perfect surface flatness, ensuring optimal pad bed-in and minimal lateral run-out (≤0.03mm). The directional cooling vane design draws air through the rotor, significantly improving heat dissipation and reducing the risk of cracking under prolonged braking.

The floating 2-piece design allows for thermal expansion without distortion, keeping the rotor self-centred with the pads. Slotted faces enhance pad bite, evacuate gas, and provide superior braking in wet conditions. Lighter than most OE rotors, these rings help reduce unsprung mass for sharper vehicle dynamics.

Key Features:
• Direct replacement rotor rings – 355mm x 28mm (13.98” x 1.10”)
• PCD: 233mm | Design: D50
• CM-250 high carbon alloy cast iron construction
• Directional vanes – up to 30% more cooling efficiency than OEM
• Slotted for improved wet/dry braking and heat dissipation
• Floating design – minimises fade, distortion, and judder
• Precision balanced and machined – ≤0.03mm run-out, ≤2g variation
• Ideal replacement for Alcon DIV2175X558 / Stasis 355x28mm rotors

Includes:
• 1x Pair of Replacement Rotor Rings (Left & Right)
• Installation Manual

Note: Rotor hat hardware sold separately. Use new hardware for safe, secure installation. Refer to Paragon’s assembly guide for torque specs and instructions.
