Paragon Performance 2-Piece Rear Rotors – Toyota GR Supra Mk5 3.0 Premium / A91
Upgrade the braking performance of your Toyota GR Supra Mk5 with the Paragon Performance 2-Piece Rear Rotor Kit, engineered for superior cooling, durability, and consistency under demanding street and track conditions. Designed specifically for the A90 GR Supra 3.0 Premium and A91 Edition, these rotors deliver race-proven performance while maintaining full OEM compatibility.
Featuring a floating two-piece design with directional ventilation vanes, the Paragon rotors actively draw cool air through the rotor to improve heat dissipation, reduce brake fade, and increase resistance to cracking during extended high-temperature use. Compared to OEM rotors, this design can operate up to 30% cooler, significantly improving braking consistency.
The rotor rings are manufactured from CM-250 special formulated high-carbon cast iron, providing excellent initial bite, stable thermal characteristics, and high-temperature strength. Each rotor is heat treated to relieve internal stress, then precision-finished using advanced CBN machining to ensure smooth bedding with new brake pads and reduced vibration.
Key Features
- Directional ventilation vanes improve airflow and cooling efficiency, running up to 30% cooler than OEM rotors
