Product Description

The EBC S9KR1275 Stage 9 "Super Sleeper" rear kit is a performance upgrade for Lexus GS300/GS430, IS300, and SC430 from 2004 to 2010. It pairs GG-rated Yellowstuff pads with Quiet USR fine-slotted rotors, offering sharper brake feel, improved cooling, and minimized dust and noise. The Brake-In™ surface coating accelerates bed-in while Geomet-coated rotors resist corrosion.

This rear-only kit bolts directly onto stock calipers and hardware. The rotors share OE bolt patterns with added height and venting for enhanced thermal handling without fitment issues. Lightweight yet robust (~26 lb), the kit installs in about 1 hour per side with basic tools. Warranty covers 12 months/10k miles for street use. Fitment confirmed through 2010; models beyond this year are unverified as of listing date.
