Paragon Performance Rotor Rings – 370x36mm / PCD 241.3mm – D55

The Paragon Performance 370x36mm rotor rings are engineered for motorsport and high-performance track applications, delivering superior braking stability, cooling efficiency, and long-term durability. Designed as a direct replacement for AP Racing CP5772-6072/6073 rotor rings, they offer a significant upgrade in performance and thermal control while reducing unsprung mass.

Each rotor ring features a directional ventilation vane design to enhance airflow through the rotor, creating suction and turbulence to evacuate heat and reduce the chance of thermal cracking. The CM-250 high carbon alloy cast iron construction provides excellent thermal stability, bite, and resistance to warping under sustained high temperatures. After casting, each ring is stress-relieved through heat treatment and precision machined with CBN tooling to ensure flatness, balance, and rapid pad bedding.

Slotted surfaces maintain a clean pad contact area, aiding in gas evacuation and brake consistency. In wet conditions, the slots help prevent water film buildup, maintaining strong initial bite. The 2-piece floating design allows for controlled thermal expansion, reduced deformation, and self-alignment with brake pads.

Key Features:

• 370mm x 36mm (14.57" x 1.42") rotor ring size
• PCD 241.3mm, D55 mounting profile
• Directional ventilation vanes for up to 30% improved cooling
• CM-250 high carbon alloy cast iron
• Precision balanced to within 2 grams; lateral run-out < 0.03mm
• Floating 2-piece design to minimise judder and fade
• Slotted face for consistent pad contact and wet weather performance
• Lightweight construction reduces unsprung mass
