Audi TT RS (8J) Front Rotors
The Girodisc Front Rotors for the Audi TT RS (8J) are engineered to deliver superior braking performance and reduced weight compared to the factory setup. Designed as a direct replacement for the OEM rotors, this lightweight two-piece system improves stopping consistency, acceleration, and suspension response without altering factory brake balance or ABS calibration.
Lightweight Direct Replacement Rotors
The Girodisc system bolts directly to your Audi TT RS without any modifications. By replacing the heavy factory rotors with high-performance two-piece units, you retain the car’s stock brake bias and ABS efficiency while enjoying reduced rotational and unsprung mass. Each Girodisc front rotor weighs approximately 19.8 lbs compared to 26.6 lbs for the OEM version — saving nearly 7 lbs per corner for sharper handling and quicker throttle response.
Vehicle Fitment
These Girodisc Front Rotors are designed specifically for:
- Audi TT RS (8J) — All model years equipped with OEM front brakes
Features
The central hat section is crafted from U.S.-sourced 6061-T6 aircraft-grade aluminum for strength and lightness. The rotor rings are made from Girodisc’s proprietary cast iron, poured and precision-machined entirely in-house in the USA. Each disc uses a curved vane design developed through motorsport testing to act as a centrifugal pump, drawing cooling air through the rotor to lower temperatures and reduce fade.
The floating mount system connects the rotor ring to the aluminum hat using 8 or 10 high-strength alloy steel drive pins, cadmium plated for corrosion resistance. These pins are secured with grade 12 cap screws and hardened washers for maximum durability. Anti-noise spring washers allow for thermal expansion while eliminating rattle, ensuring smooth, quiet operation both on the street and track. The floating design also allows the rotor to self-center between pads, maintaining consistent brake feel under all conditions.
Once installed, the Girodisc system makes future maintenance simple — only the cast iron rotor rings need replacement when worn, while the aluminum hats can be reused for years of service.
