Product Description

The EBC S4KR1451 Rear Brake Kit is a Stage 4 performance upgrade designed specifically for the rear brakes of select Audi S3 and Audi TTS Quattro models. This kit pairs EBC's Redstuff ceramic low-dust brake pads with USR fine-slotted sport rotors that help dissipate heat and evacuate debris under heavy use. The result is improved stopping power with reduced fade compared to many stock rear brake setups.

Installation is direct bolt-on using the factory rear 5-lug hubs on compatible Audi S3 and TTS models - no modifications required. The thermic black/Geomet anti-rust coating on the rotors enhances corrosion resistance for long service life, making this a strong upgrade choice for spirited daily driving or occasional aggressive use. Always verify your specific year, trim, and drivetrain to ensure proper fitment before installation.
