Product details
Slotted two-piece rotors at 14 in, or 356 mm, sit on this Procomp front kit for the 2009 to 2013 Audi A3. The eight-piston calipers are one-piece billet aluminum, and the kit comes with SC1 street pads, stainless braided lines and CNC-machined caliper brackets with hardware.
Wheels of 18 in or larger are the planning figure, about 4 in over the rotor, so check clearance before buying. The approved application is the 2009 to 2013 Audi A3 chassis 8P, and the Quattro from 2003 to 2013 is listed under the same OE two-piece caliper condition.
Use the year, make and model checker to confirm fitment. Keep the OE caliper condition in mind when comparing the Quattro entry, since it applies to every A3 entry in this range. Two-piece rotors are built for light weight, fade-free performance and grip on the track.
Supported features
Lightweight 6-pot aluminum calipers are standard on 11 in and 12 in front systems; 8-pot calipers on 13 in and 14 in. The opposed-piston design greatly improves pad wear and caliper rigidity over OEM.
Lightweight 2-pot aluminum calipers are standard on 11 in and 12 in rear kits; 4-pot on 13 in and 14 in systems.
Two-piece rotors provide light weight, fade-free performance and grip on the track with comfortable, easy operation under normal driving.
CNC-machined carbon steel brackets let the larger calipers bolt to the OEM caliper bracket location.
Cross-drilled rotors run cooler and are recommended for daily-driven vehicles; slotted rotors are recommended for vehicles that see more track use.
NAOC ceramic street pads (194–1022°F operating range) reduce dust and rotor wear; DOT-compliant stainless braided lines resist expansion for a firmer, quicker pedal.
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.
