Product details
This Supercomp front kit for the 2009 to 2013 Audi A3 uses eight-piston one-piece billet aluminum calipers and 15.7 in, or 400 mm, two-piece cross-drilled rotors with aluminum center bells. The box holds SC5 street brake pads, stainless braided lines, CNC-machined caliper mounting brackets and hardware. The calipers are fixed to the car at the factory bracket location, and the stainless lines carry the hydraulic pressure through the front axle.
Cross-drilled rotors run cooler, which suits a car driven every day. The approved application is the 2009 to 2013 Audi A3, and the 2003 to 2013 Audi A3 Quattro is also listed, both limited to models with the OE two-piece caliper.
The drivetrain is listed as 2WD unless otherwise stated, so confirm yours. Use the year, make and model checker before ordering, and check your brake layout against the OEM master cylinder and ABS.
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.
