Product details
This rear Supercomp kit fits the 1989-1993 Porsche 964 in C2 RWD form. It pairs two 4-piston calipers machined from one-piece billet aluminum with 13 in. (330 mm) two-piece cross-drilled rotors, and each rotor carries an aluminum center bell. The bolt-on design uses CNC-machined carbon steel brackets and the hardware supplied.
Cross-drilled rotors run cooler, a sensible match for a 964 that sees regular road use. SC5 street pads come standard. Race pads, titanium center bells, twin-color anodized center bells and painted, polished or anodized caliper finishes are optional. The 911 is also listed for this kit, and the owner's manual is included.
Stainless braided lines are part of the package and give a more responsive pedal than OEM rubber lines. Check your exact year and body with the KSport checker, and expect some noise until the brakes warm up.
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.
