Product Description

The EBC S9KR1233 Stage 9 Rear Brake Kit delivers high-performance braking for select Infiniti models - including FX50, M37, M56, Q50, Q60, Q70, and QX70 - covering model years 2009 through July 2023. This bolt-on kit enhances rear braking with 350 mm vented and finely slotted USR rotors, engineered to dissipate heat efficiently while reducing noise and vibration. Golden-yellow GG-rated Yellowstuff pads provide aggressive stopping power ideal for spirited street or occasional track use.

Rotors feature Thermic/Geomet coating to resist corrosion, while EBC's patented Brake-In pad surface expedites break-in. Installation is seamless with OEM rear calipers - no modification or additional hardware required. Includes lubricant packet but not brake fluid. Backed by a 12-month/10,000-mile street-use warranty; race or drift applications void coverage. For optimal braking balance, EBC mandates matching front pad upgrades; do not mix upgraded rear pads with OEM fronts.
