Product Description

The EBC S5KR1230 is a rear axle performance brake kit designed for Ford Mustang S197 models from 2005 to 2012. It combines EBC Yellowstuff high-friction brake pads with GD series slotted and dimpled rotors to improve braking performance, heat management, and fade resistance compared to OEM rear braking systems.

The ~300 mm rear rotor system is engineered for Mustang performance applications, delivering stable thermal capacity for spirited street driving and occasional track use. The slotted and dimpled rotor design helps evacuate heat, gases, and debris from the braking surface, maintaining consistent braking performance under repeated high-load braking.

This kit installs as a direct rear axle replacement for compatible Mustang platforms without modification. It is ideal for drivers seeking improved braking confidence, durability, and fade resistance for performance street and track-oriented driving.
