The GR Yaris shares its brake architecture with the GR Corolla, and Triton Motorsports' two-piece floating disc brake rotors bring the same real weight savings to it — a billet aluminum hat paired with a separate high carbon iron alloy disc, built for a car whose whole identity is built around light weight and quick reflexes.
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 is upgraded 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.
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
