Paragon Performance Rotor Rings 378x36mm – PCD240 – 12x6.4mm Mounting – D55

Paragon Performance Rotor Rings are engineered for maximum braking efficiency and thermal stability in high-performance track and racing environments. Featuring a slotted, directional design and advanced metallurgy, these 2-piece floating rotor rings offer exceptional durability, cooling performance, and pedal consistency under extreme conditions.

Constructed from CM-250 high carbon alloy cast iron, each ring is heat treated to reduce internal stress and enhance thermal resistance. State-of-the-art CBN surface machining ensures optimal pad contact and consistent brake feel from the first stop. Slotted face design improves pad bite, clears debris, and maintains performance in both dry and wet conditions.

With directional ventilation vanes and a floating design, Paragon rotor rings minimise heat-related deformation, reduce brake fade, and support longer, more consistent sessions on the circuit. Precision balancing and strict manufacturing tolerances ensure vibration-free performance and exceptional rotor longevity.

Key Features

• Directional ventilation vanes for enhanced airflow and reduced rotor temperatures

• Slotted rotor face for consistent braking performance and gas dissipation

• Floating 2-piece design allows thermal expansion and self-alignment with brake pads

• CM-250 high carbon alloy construction with stress-relief heat treatment

• Precision machined for low lateral run-out (<0.03mm)

• Balanced to within 2 grams for vibration-free braking

• Lightweight design (9.45kg each) to reduce unsprung mass

• Superior thermal stability and resistance to cracking or warping
