Vehicle Fitment

• 2015-2016 Audi RS3 (8VA/8VF) Sportback, 2.5 TFSI Quattro (367 HP / 270 kW)
• 2017-2020 Audi RS3 (8VF Facelift) Sportback, 2.5 TFSI Quattro (400 HP / 294 kW)

Fitment Notes

• Fits Audi RS3 8V Sportback (8VA/8VF) with PR code 1LH or 1LU (standard 8-piston Brembo front brake system, 370mm)
• Does not fit RS3 8V Sedan (8VS/8VM) - Sedan uses a different OE rotor specification
• Does not fit RS3 8Y (2022+) - different platform and brake architecture
• Verify PR code on vehicle data sticker before ordering

Features

• Dual Cast construction: cast iron braking surface bonded to an aluminum hat for reduced weight and less thermal deformation
• Cross-drilled surface improves heat dissipation and resists brake fade under repeated hard stops
• UV coating provides superior corrosion protection on all disc surfaces, including the braking band

Product Description

The Brembo 09.D174.33 is an OE-equivalent front brake rotor engineered specifically for the Audi RS3 8V Sportback. Built using Brembo's exclusive Dual Cast technology, the rotor pairs a cast iron braking surface with a lightweight aluminum hat - delivering the heat resistance of iron with a meaningful reduction in unsprung weight. The cross-drilled design improves airflow across the disc, helping the brakes shed heat faster and maintain consistent pedal feel during spirited or repeated heavy braking. UV coating protects the entire disc surface from corrosion, keeping the rotor looking clean and performing reliably across all weather conditions.

This rotor is a direct replacement for the factory 8-piston Brembo front brake system found on the RS3 8V Sportback with PR codes 1LH or 1LU. No modifications or adapter hardware are needed - simply confirm your PR code on the vehicle data sticker and bolt on. Brembo recommends pairing this rotor with Brembo NAO/Ceramic or Low Met brake pads, and replacing both rotors and pads together to restore full braking performance. ECE R-90 certified and built to meet or exceed Audi OE material specifications.
