Triton Motorsports' two-piece floating disc brake rotors bring true two-piece rotor construction to the Toyota GR Corolla — a billet aluminum hat paired with a separate high carbon iron alloy disc, engineered to cut real weight from a car built around light weight and agility.
The front rotor keeps the factory 356x28mm size but drops from 22.05 lbs (10kg) stock to 20.35 lbs (9.23kg) — a 7.7% weight reduction per corner. The rear goes further: we upgrade from the factory 297x18mm rotor to a larger 320x18mm disc, while still cutting weight from 13.07 lbs (5.93kg) to 11.68 lbs (5.3kg), a 10.6% reduction — more braking surface and less rotating mass at the same time.
Key Features:
- Splitting the rotor from the hat lets each move independently as heat builds, reducing the warping a fused one-piece disc develops under hard driving
- Front: 356x28mm, 20.35 lbs (9.23kg) — 7.7% lighter than the 22.05 lb (10kg) factory rotor
- Rear: upgraded to 320x18mm (from factory 297x18mm), 11.68 lbs (5.3kg) — 10.6% lighter than the 13.07 lb (5.93kg) factory rotor, with more disc diameter for improved heat capacity
- Front installs as a direct fit; rear requires the included spacer to accommodate the larger rotor diameter
