Product details
On the 2006-2012 Lexus GS350 (AWD excluded), this Slimline kit puts 3-piston billet aluminum calipers over 13 in (330 mm) slotted two-piece rotors. The rotors come with aluminum center bells, and the box holds SC5 street pads, stainless braided brake lines and CNC-machined carbon steel brackets with hardware.
Slimline calipers are typically chosen when room behind the wheel is limited. Keep the OEM handbrake issue in mind: this kit does not keep the stock handbrake working, so review your parking-brake setup before installation.
Wheel guidance is 17 in or larger, about 4 in over the rotor, so verify the wheel barrel and spokes against the caliper. Confirm fitment with the year, make and model checker, because AWD vehicles are outside this application. Rotor size and wheel clearance should be checked together, since the kit is built around the 13 in slotted set.
Supported features
A single-side piston caliper that keeps the styling of the multi-piston calipers while fitting behind wheels with limited clearance.
Extremely lightweight two-piece rotors — commonly up to 50% lighter than OEM rotors of the same size.
Calipers, floating brake discs, SC5 street pads, owner's manual, and all required hardware come standard.
CNC-machined carbon steel brackets let the calipers bolt to the OEM caliper bracket location.
Cross-drilled rotors run cooler for daily-driven vehicles; slotted rotors are recommended for more track use.
Standard painted orange, red, black, and yellow; premium high-polish silver, gold, and titanium; glassy and hard-anodized finishes; over 20,000 custom colors on request.

This part number ships with slotted rotors. Slotted suits track use; the cross-drilled version of this kit suits daily driving. Both versions are listed on the Slimline page.
Painted KSport orange, race red, caution yellow or jet black at no extra charge. Premium high-polish, glassy and hard-anodized finishes cost extra.
Street pads are standard; race pads, titanium or twin-colour anodized center bells are optional upgrades.
Choose the caliper finish, pads and center-bell configuration above. Every selection and any extra charge is shown before Add to Cart and saved with the order. Contact KSport for a custom color quote.
Installation
Bolt-on installation with the supplied brackets; no vehicle modification on most applications. After fitting, bed the pads in: on a clear road, ten light-to-medium stops from 30–45 mph, three seconds each, at least a quarter mile apart. Some noise before the brakes warm up is normal for big brake kits.
Brake system support and bed-in procedureWarranty & service
12-month limited warranty to the original purchaser against defects in materials and workmanship. Racing use, exterior finish and improperly installed or modified parts are not covered; keep your original invoice for any claim. Small surface cracks on cross-drilled rotors are normal wear and not a defect. Replacement pads, rotors, lines and hardware are sold individually.
