Product details
This Slimline front kit for the 2009 to 2013 Audi A3 pairs two three-piston calipers, each one-piece billet aluminum, with two 13 in two-piece cross-drilled rotors that carry aluminum center bells. The box also includes SC5 street brake pads, stainless steel braided brake lines and CNC-machined caliper mounting brackets with hardware.
The approved application is the 2009 to 2013 Audi A3, and the Quattro from 2003 to 2013 is also listed. Both entries are limited to models with the OE two-piece caliper, so check that detail on your car before you commit. The factory master cylinder and ABS stay in service with this kit.
Cross-drilled rotors suit daily driving, and this part number is built with them. Plan on 17 in or larger wheels, about 4 in over the rotor, and check the barrel and spokes for room. Confirm the 8P chassis with the year, make and model checker, since the drivetrain entry is 2WD unless noted otherwise.
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.

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.
