Specifications — BKAU071-971SO
Product details
Supercomp calipers for the 2009 to 2013 Audi A3 pair with two-piece slotted rotors in the 16.6 in size on this front kit, part number BKAU071-971SO. Eight-piston calipers are part of the Supercomp range, and SC5 street pads, stainless braided lines and caliper mounting brackets with hardware are included.
Slotted rotors suit more track use, and cross-drilled rotors are the cooler-running option for daily driving. The approved application is the 2009 to 2013 Audi A3, with the Quattro from 2003 to 2013 also listed under the OE two-piece caliper limit.
Plan the fit around the year, make and model checker before you buy. The kit works with the OEM master cylinder and ABS, so the factory hydraulic layout stays in service, and drivetrain is 2WD unless otherwise stated. Keep your original invoice handy for any fitment question, since the year, make and model are the first checks.
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.
