Triton Motorsports' floating brake discs bring true two-piece rotor construction to the 8Y Audi RS3 — a billet aluminum hat paired with a separate high carbon iron alloy disc ring, built as a direct replacement for the factory setup with no modification required.
The floating design allows independent movement between the rotor and hat under heavy braking, reducing stress on the braking components and preventing the warping a fixed one-piece rotor is prone to under extreme conditions. That means more even wear and consistent, predictable braking performance whether you're navigating city streets or pushing the RS3 on track.
Key Features:
Two-Piece Floating Construction — independent movement between rotor and hat reduces stress and prevents warping under extreme conditions
High Carbon Iron Alloy Disc Ring — handles thermal loads effectively, reducing the risk of brake fade under hard driving
Billet Aluminum Hat — lowers unsprung weight versus a fixed rotor, supporting sharper cornering and responsiveness 
Direct OEM Replacement — installs in place of the factory disc, no modifications or additional components required
