Triton Motorsports' floating disc brake rotors bring true two-piece rotor construction to the 991 Porsche GT3 — a 6061-T6 billet aluminum hat paired with a separate G3500 high carbon iron alloy disc, built as a direct replacement for the factory setup with no modification required.
The floating design allows the disc to move independently of the hat as temperatures rise, reducing stress on the braking system and preventing the warping a fixed rotor is prone to under sustained heat. For a car built to spend real time on track, that means more consistent, fade-resistant braking whether you're carving mountain roads or pushing the GT3 to its limit.
Key Features:
- Splitting the rotor from the hat lets each move independently as heat builds, preventing the warping a fused one-piece disc develops under repeated track use
- The G3500 iron alloy composition is formulated to keep dissipating heat rather than fading during sustained hard braking
- A 6061-T6 aluminum hat trims unsprung weight versus the factory rotor, aiding turn-in and agility
- Installs directly onto the OE hub and caliper — no modifications required
- A rotor that stays true under heat keeps pad contact even, extending pad life
