Caliper render for this kit:

On a front-wheel-drive A3 8V, the rear axle is the quiet partner in every stop. The fronts shoulder most of the load while the standard rear setup is sized for economy, not repeat heavy use. This XYZ Racing Hollow rear big brake kit addresses that imbalance, giving the back of the car a disc and caliper with the thermal headroom to keep pulling its share when you string corners together or drop down a long hill with the car loaded.
The 1.6 TDI is a torquey, weight-over-the-nose commuter and B-road car rather than an outright track weapon, so the rear kit’s job here is consistency and balance rather than raw stopping power. Run alongside a matching front upgrade or fitted on its own to firm up pedal feel, it brings the rear into the conversation without upsetting how a frugal diesel A3 behaves day to day.
What this brake kit does for your 2013-2026 Audi A3 8V Sportback (2WD) 1.6TDI
The first thing you notice after fitting is a firmer, more progressive pedal as the rear contributes more usefully to each stop. The two-piece floating disc sheds heat faster and trims rotating mass, which matters on a diesel that spends its life carrying passengers, luggage or a small trailer. Three pad compounds let you set the rear’s bite to match how you drive: Street for quiet commuting with low dust, Sport for harder fast-road work and a wider heat range, and Racing for the most aggressive stops. Because the rear stays cooler and more settled, the whole car resists the fade and long-travel pedal that creeps in on extended descents or back-to-back stops. With selectable caliper colours from the included painted finishes through to premium polished and candy options, the upgrade also reads clearly through the wheel spokes.
About the Hollow Rear Brake Kit
The rear brake kit is XYZ Racing’s bolt-on disc and caliper package built specifically for the A3’s rear axle rather than a universal fit. It centres on a two-piece floating disc that moves heat away from the friction surface and shaves rotating weight, both of which help the brakes recover between applications. The caliper is hollow-bodied as standard to keep mass low and clamps a larger swept area than the factory rear; the kit ships with your choice of pad compound, Street for road use, Sport for harder fast-road driving, and Racing for the most aggressive bite. For sustained track work there is an optional Hollow Racing build with no dust cover, a 1000C rating and a two-year warranty. Caliper colour is specified when you order, with Red, Yellow, Gold, Black and Anodized Black included at no extra cost, a Custom Color in any Pantone for £150, and premium polished-forged finishes in Titanium, Polished Gold and Polished Silver alongside candy finishes in Teal, Blue, Red and Orange. Everything is sized around the A3’s existing hubs and wheel package, so it works within the car’s standard architecture instead of forcing changes elsewhere.
Fitment for the Audi A3 8V Sportback (2WD) 1.6TDI (2013-2026)
This kit is mapped to the 8V-generation A3 Sportback in front-wheel-drive 1.6 TDI form, covering the 2013 to 2026 model span. It fits the rear axle specifically, so confirm your car is the 2WD diesel variant rather than a quattro or petrol model before ordering. Caliper colour and pad compound are both selected as part of the build.

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 330–356mm (rear). 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.
