GiroDisc A1-180 2-Piece Slotted Front Rotors for 2015-2020 Audi RS3 8V Sedan

Vehicle Fitment

• 2015-2020 Audi RS3 Sedan (8V), front axle - compatible with standard or CCM (carbon-ceramic) OEM brake setup

Features

• 2-piece floating rotor design - billet aluminum hat + cast-iron rotor ring to reduce unsprung and rotational mass
• Slotted, vented rotor surface for improved pad bite, efficient heat dissipation and gas/debris purge under heavy braking
• Curved-vane internal ventilation - acts like a centrifugal pump to pull cooling air through the rotor for consistent heat management
• Floating-mount with high-strength alloy steel drive pins and anti-noise spring washers - allows thermal expansion without warping or rattling
\li>Direct bolt-on replacement - works with OEM calipers and pads, no special modifications needed
• Rotors ~24.0 lb each vs ~27.4 lb stock - lighter rotating & unsprung mass improves throttle response, suspension and steering feel
• Re-useable hat design - rotor rings can be replaced when worn, reducing long-term maintenance cost
• Maintains factory brake bias and ABS calibration - no need for caliper or brake system upgrades

Product Description

The GiroDisc A1-180 front rotor set is a direct-fit, high-performance upgrade designed for the front brakes of 2015-2020 Audi RS3 8V sedans. By replacing OE rotors with a two-piece floating design that combines a lightweight 6061-T6 aluminum hat and a high-carbon cast-iron rotor ring, the A1-180 significantly reduces rotating and unsprung mass. The weight savings (~3.4 lb per rotor) lead to sharper throttle response, improved steering precision and more responsive suspension behavior - especially noticeable during aggressive driving, braking or spirited street use.

With slotted and vented disc surfaces and curved-vane internal ventilation, these rotors manage heat and pad-gas discharge efficiently, helping maintain consistent braking performance under repeated heavy stops or track-day use. The floating mount system uses high-strength alloy pins and spring-washers to allow thermal expansion while avoiding warping, vibration or noise - and the reusable-hat design keeps future maintenance simple and cost-effective: when the rotor rings wear, you only replace the rings, not the hats. Because A1-180 bolts directly to the stock hubs and retains OEM caliper and pad compatibility, it preserves brake bias and ABS calibration - giving a substantial braking upgrade without needing a full big-brake kit. For RS3 owners seeking improved braking modulation, reduced unsprung mass, and strong, fade-resistant stopping power - GiroDisc A1-180 is an excellent upgrade.
