Product Description

The EBC S9KF1538 is a front Stage 9 brake kit that combines Yellowstuff high-friction brake pads with USR sport slotted rotors for a matched performance brake 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 dust, gas, and debris while maintaining a quieter on-road character than more aggressive slot patterns.

Cross-validated fitment supports front application for the 2011-2017 BMW X3 xDrive35i and 2015-2018 BMW X4 xDrive35i, both using the 3.0L turbocharged inline-6 engine and AWD drivetrain. I did not expand fitment beyond these applications because I could not confirm additional trims, engines, or drivetrains to the required standard from the sources reviewed. No lift or drop height applies because this is a brake kit, not a suspension component. Fitment confirmed through 2018 on reviewed sources. 2025 coverage unconfirmed at time of listing.
