Caliper render for this kit:
The 8P-series A3 Sportback quattro runs a Haldex 4WD system, reactive rather than mechanical, routing torque rearward on demand rather than permanently splitting drive. Under braking, the front axle carries nearly all the retardation load before the rear clutch pack can respond, which puts the factory front setup under more sustained pressure than the all-wheel-drive badge might suggest. For owners of the higher-spec 2004-2013 Sportback variants fitted with the two-piece OE front caliper, typically the higher-output engine lines and S line trims, the original hardware is capable but was not designed with repeat track sessions or extended mountain-road running in mind.
This XYZ Racing front brake kit is built for exactly that gap. It is a front-axle pair: left and right front calipers with matched two-piece floating discs, and three pad compounds that let you configure the front end to your actual driving rather than accepting a single grade that compromises either cold-bite or high-heat endurance.
What this brake kit does for your 2004-2013 Audi A3 Sportback (4WD)
Fitting the larger two-piece discs increases thermal mass and swept area at the leading axle, precisely where an 8P quattro Sportback needs it most. The hollow-vane disc design improves heat dissipation over a solid-face vented rotor, which translates to more consistent pedal pressure and reduced fade across successive heavy stops. The lighter two-piece discs also cut rotating and unsprung mass at the front, and braided lines hold the pedal firm under load.
The Sport compound suits an owner covering serious fast-road mileage who needs reliable cold-bite without the harshness of a track pad; step up to Racing for circuit work and the front end gains the sustained fade resistance the factory setup cannot match across an afternoon of sessions; Street is the quiet, low-dust road default. Calipers are hollow-bodied as standard, with a Hollow Racing upgrade for serious track use, rated to 1000C, no dust cover, two-year warranty.
About the Front Brake Kit
XYZ Racing’s front brake kit is a front-axle replacement built to deliver better sustained performance than the OE specification. The two-piece floating disc reduces weight without the stress concentrations associated with fully drilled rotors, a distinction that matters for a car seeing regular road use alongside occasional circuit work. Pad compound spans Street through Sport to Racing, covering everything from a daily-driven A3 quattro to one used for endurance lapping. Discs come in drilled or slotted face at the same price, with optional two-tone centre bells in five anodized colours or titanium at checkout. Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost; a Custom Color in any Pantone is £150, with premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy finishes (Teal, Blue, Red, Orange) also available.
Fitment for the Audi A3 Sportback (4WD) (2004-2013)
This kit is specified for the 8P-series Audi A3 Sportback quattro produced between 2004 and 2013. The fitment carries an important qualifier: it is compatible only with cars equipped from the factory with a two-piece front caliper. That configuration is typically found on higher-spec engine and trim variants within the 8P range and is distinct from the standard single-piece sliding caliper fitted to lower-specification models. Confirm your existing caliper type before proceeding.

Choosing your spec
Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.
Brake pads — Street, Sport or Racing
Every kit ships with a full set of high-performance pads; the compound is your call.
Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.
Caliper grade — Hollow vs Hollow Racing
Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.
Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 286–380mm (front). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.
Caliper colour & finish
Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).
Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.
Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).
Centre bells
The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
