Product Description

The EBC S9KR1548 is a rear Stage 9 brake kit that combines Yellowstuff high-friction brake pads with USR sport slotted rotors for a matched performance upgrade. It is intended for drivers who want stronger initial bite, improved stopping consistency, and better resistance to heat-related fade than standard replacement components. The USR rotor design uses fine sport slots to help sweep away gas, dust, and debris while reducing wind noise compared with more aggressive slot patterns.

Cross-validated fitment supports rear application for the Audi S3 and Audi TTS Quattro using the 310 mm vented rear rotor setup with ATE rear brakes and FMSI D1761 pad shape. Confirmed applications include 2015-2020 Audi S3 2.0L turbo AWD and 2019 Audi TTS Quattro 2.0L turbo AWD. I did not expand fitment beyond these vehicles because I could not confirm additional applications to the required standard from at least two trusted sources. No lift or drop height applies because this is a brake kit, not a suspension component. Fitment confirmed through 2020 on reviewed sources. 2025 coverage unconfirmed at time of listing.
