Caliper render for this kit:

The C7-generation A6 in 2WD form hangs its longitudinal engine ahead of the front axle, so the rear contributes a smaller share of braking than the nose does. That makes the rear axle easy to overlook, right up until a fast B-road descent or a track session reveals the standard rear discs heat-soaking and the pedal travelling long. This XYZ Racing Hollow Rear Brake Kit for the Audi A6 C7 2WD (TYPE I) addresses exactly that weak point.
Specified for 2012-2018 cars, it adds thermal capacity and bite where the factory rear setup runs out of room. Two-piece floating discs trim rotating mass, and a choice of Street, Sport or Racing pad compounds lets you match the rear axle to how hard you actually drive.
What this brake kit does for your 2012-2018 Audi A6 C7 2WD (TYPE I)
On a saloon this heavy, rear brake fade shows up as a soft, travelling pedal and a nose-down attitude under repeated stops. The two-piece floating disc gives the rear axle more surface area to shed heat, so the pedal stays firm through a sequence of hard stops. Stepping up to the Sport or Racing compound sharpens initial bite and raises the fade threshold for track-day work, while the Street compound keeps a daily-driven A6 quiet and clean with low dust. Better rear thermal stability also helps the car rotate more honestly on turn-in rather than washing into understeer. Selectable caliper finishes, from the included painted colours through to premium polished and candy options, mean the upgrade reads behind the wheels as clearly as it does through the pedal.
About the Hollow rear brake kit
The rear brake kit is XYZ Racing’s answer to a heavy front-engined A6 whose rear brakes were specified for normal road use rather than sustained hard driving. The two-piece floating disc removes material from the rotor to cut rotating mass without surrendering thermal capacity, which sharpens how quickly the rear axle responds. The caliper is hollow-bodied as standard to keep weight down, with an optional Hollow Racing build for sustained high-temperature use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Three pad compounds are offered: a Street compound for quiet, low-dust everyday driving, a Sport compound for spirited road work, and a Racing compound built to resist fade under sustained high-temperature use. 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, premium polished-forged finishes in Titanium, Polished Gold and Polished Silver, and candy finishes in Teal, Blue, Red and Orange. As a rear-axle setup, a matched pair of rear calipers and discs with braided lines, it is designed to pair with a matching front kit or to rebalance braking bias toward a car that sees more track and fast-road use than the original specification allowed for.
Fitment for the Audi A6 C7 2WD (TYPE I) (2012-2018)
This kit is specified for the C7 A6 in 2WD (TYPE I) form, covering model years 2012 to 2018, and fits the rear axle only. Confirm your car is the front-driven 2WD chassis rather than a quattro variant before ordering, since the two carry different rear hardware.

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.
