Paragon Performance 2-Piece Rear Rotors – Toyota GR Supra A90/A91 (3.0 Premium / A91)

Upgrade the braking performance of your Toyota GR Supra with the Paragon Performance 2-Piece Rear Rotor Kit, engineered for superior cooling, durability, and consistency under both street and track conditions. Designed specifically for the A90 GR Supra 3.0 Premium and A91 models, these rotors deliver race-proven performance while maintaining full OEM compatibility.

Featuring a floating two-piece design with directional ventilation vanes, these rotors actively draw cool air through the disc to improve heat dissipation, reduce brake fade, and enhance reliability during extended high-temperature use. Compared to factory rotors, this system can operate up to 30% cooler, delivering more consistent braking performance.
