Caliper render for this kit:

The 8X A1 carries its braking effort heavily over the front axle, which is exactly why the rear discs on these diesel superminis spend most of their life barely warm and under-worked. This XYZ Racing Hollow Rear Brake Kit for the Audi A1 1.6 TDI (8X) gives the back axle a stronger, more consistent share of the work, sharpening the balance of a car that was set up from the factory to under-use its rear brakes.
For a torquey 1.6 TDI used hard on a fast B-road or loaded up for motorway miles, that matters. A rear axle that actually contributes settles the car earlier into a corner and takes some of the thermal load off the fronts, so the whole system stays composed when you start asking more of it. The kit is a matched pair of left and right rear calipers and two-piece floating discs.
What this brake kit does for your 2010-2018 Audi A1 1.6 TDI (8X)
The hollow-vane disc core strips rotating mass from the rear axle, which the light 8X chassis feels as a touch less unsprung weight and quicker pedal response. Behind the wheel you get a firmer, more predictable rear contribution under braking, steadier balance on turn-in, and longer pad life because the front axle is no longer doing nearly all the thermal work alone.
Pad compound sets the bite to suit the car. Street is the quiet, low-dust default for daily diesel running. Sport gives keener fast-road feel and copes with the odd track day. Racing handles repeated heavy stops where a stock rear pad would glaze and fade. The included caliper finishes are Red, Yellow, Gold, Black and Anodized Black, with any Pantone available as a Custom Color.
About the Hollow Rear Brake Kit
The kit pairs two-piece floating rotors on a hollow-vane core with position-matched calipers built specifically for the rear of the A1. The hollow-vane construction lowers rotating mass without giving up swept area, so heat capacity stays sensible while the axle responds faster. Pad compound is the main tuning lever here, with Street, Sport and Racing options covering the full span from economy commuter to track-day weekend.
Disc face is drilled or slotted at the same price, and centre bell upgrades, two-tone anodizing in five colours or titanium, are selectable when you order. The caliper is hollow-body as standard, with premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange beyond the included colours. A Hollow Racing caliper, with no dust cover, a 1000C rating and a two-year warranty, is there for serious track use. The whole package is built around restoring proper front-to-rear brake balance on a chassis that leans hard on its front axle.
Fitment for the Audi A1 1.6 TDI (8X) (2010-2018)
This kit is matched to the 8X-generation Audi A1 in 1.6 TDI form, covering the 2010 to 2018 production span. It fits the rear axle. Confirm your exact build year and trim against the chassis code before you order so the caliper and rotor spec lines up with your car.

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.
