Caliper render for this kit:

The 8V A3’s front-drive MQB layout carries most of its mass over the nose, which leaves the rear axle lightly loaded and the standard rear discs doing comparatively little of the work. The XYZ Racing Hollow Rear Brake Kit for the Audi A3 8V Sportback (2wd) 1.2T rebalances that picture, giving the back axle more thermal headroom and a firmer, more progressive pedal.
It is a bolt-on rear upgrade aimed at owners who push their 1.2 TFSI harder than the factory hardware was specified for. Repeated stops on a quick back road, the odd track day, or a car that has simply gained weight in spec and luggage all ask more of the rear than the OE setup was sized to give. The two-piece floating disc trims rotating mass while keeping a usable swept area for a hatch of this size.
What this brake kit does for your 2013-2026 Audi A3 8V Sportback (2wd) 1.2T
On a front-driven A3 the rear brakes shape how the car rotates into a corner. Adding capacity at the back sharpens turn-in under trail braking and steadies the chassis when you lift mid-corner, a trait the lighter base 1.2T feels more readily than the heavier quattro models. Three pad compounds let you match bite and fade resistance to how the car is actually used: Street for quiet, low-dust daily running, Sport for harder fast-road work with a higher heat range, and Racing for sustained track stops. Shedding rotating mass at the rotor also helps the rear suspension settle faster over broken Tarmac, and with the caliper colour yours to choose the kit reads as deliberate behind the wheels.
About the Hollow rear brake kit
The rear kit is a complete rear-axle package, a pair of left and right rear calipers with matched discs, mounting hardware, pads and braided lines, sized for the 8V A3 Sportback. The two-piece floating disc sheds heat while shaving weight off each corner, useful on a light rear axle where any saving is felt at the wheel. The caliper body is hollow as standard to keep mass down, with an optional Hollow Racing build for serious track use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Bite is tuned through the three pad compounds, from the Street pad’s refined road manners to the Racing pad’s repeated high-temperature work. Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150, plus premium polished-forged finishes in Titanium, Polished Gold and Polished Silver and candy finishes in Teal, Blue, Red and Orange. The kit is meant to work as a balanced partner to a front upgrade rather than a standalone fix, keeping brake bias sensible front to rear.

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.
