Product details
The slotted Supercomp rear kit for the 1992-2000 Lexus SC400 JZZ30 uses 14 in two-piece slotted rotors with four-piston calipers. The slotted face is the main difference from the drilled 447CO version. Slots make the rear look different from the drilled Supercomp kit.
Included are two Supercomp rear calipers, two 14 in slotted rotors with aluminum center bells, SC5 street brake pads, braided stainless-steel lines, and CNC-machined caliper brackets with hardware. Color is chosen during configuration, and the kit is for the rear axle only. The rotors are two-piece units.
Use the year, make and model checker for the SC400 and keep part number BKLX100-447SO on the order. Measure wheels of 18 in or larger against the barrel and spokes, since the planning rule is about 4 in over the rotor. Fitment is confirmed by the year, make and model checker before ordering.
Supported features
One-piece construction from a solid billet of aerospace-quality aluminum rather than cast or welded, for even thickness and strength across the caliper block.
The outer section shifts slightly as needed for better self-centering in the caliper, lowering brake drag and boosting performance through more even application.
Calipers, floating brake discs, SC5 street pads, owner's manual, and all required hardware come standard.
CNC-machined carbon steel brackets let the larger 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.
DOT-compliant stainless braided lines stop expansion under pressure for quicker response and a firmer pedal than stock rubber lines.
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.

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.
