Caliper render for this kit:

The C7 A6 carries a lot of its weight ahead of the front axle, and on the 2WD (TYPE II) cars that nose-heavy layout means the rear brakes spend most of their life as supporting players. Lean on them hard and often, though, with long descents, committed B-road work or the odd track day in a near-1,800kg saloon, and the standard rear setup runs short of thermal headroom before the fronts do.
The XYZ Racing Hollow Rear Brake Kit for the Audi A6 C7 2WD (TYPE II) is built to put that balance back. It pairs a two-piece floating disc that trims rotating and unsprung mass with a choice of pad compounds, so the rear axle keeps contributing when the brakes get hot rather than fading into the background.
What this brake kit does for your 2012-2018 Audi A6 C7 2WD (TYPE II)
Fit this kit and the first thing you feel is a firmer, more progressive pedal that does not go long after a sequence of heavy stops. The two-piece floating disc carries less rotating mass than a solid equivalent, which sharpens response at the rear corners and eases the load the suspension manages over broken surfaces. On a front-biased car like the C7, adding genuine rear thermal capacity steadies the brake balance under trail-braking, so the back axle stays planted instead of letting the nose run wide. The three pad compounds let you match bite and friction to how you actually drive: Street for quiet road use, Sport for harder fast-road work, and Racing for sustained circuit sessions.
About the Hollow Rear Brake Kit
The kit centres on a two-piece floating disc: material is removed from within the rotor to cut rotating and unsprung weight while keeping the swept area needed to shed heat. Less mass spinning at each rear wheel means quicker response and lower thermal inertia, so the discs come up to temperature predictably and cool faster between stops. The caliper is hollow-bodied as standard to keep weight down, with an optional Hollow Racing build for circuit work that removes the dust cover, is rated to 1000C and carries a two-year warranty. XYZ Racing offers the kit in three pad compounds, Street for road comfort and low dust, Sport for harder fast-road use, and Racing for circuit work, plus included painted caliper finishes in Red, Yellow, Gold, Black and Anodized Black at no extra cost, 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. It is a rear-axle kit, a matched pair of rear calipers and discs with braided lines, intended to complement a front upgrade and restore braking balance on the heavier C7 A6.
Fitment for the Audi A6 C7 2WD (TYPE II) (2012-2018)
This kit is specified for the C7-generation Audi A6 in 2WD (TYPE II) form, covering the 2012 to 2018 model years, and fits the rear axle only. Confirm your car matches the C7 chassis and the 2WD drivetrain before ordering, as the front kit and the quattro variants use different 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.
