Caliper render for this kit:

The first-generation 8R Q5 was never light on its feet. Most of its mass sits over the nose, and on a 2WD car that weight pitches hard onto the front axle under braking, which leaves the rear discs doing quieter, but no less important, work managing balance and shedding heat on long descents. The XYZ Racing Hollow Rear Brake Kit for the Audi Q5 2WD 8R (TYPE1) targets the rear axle specifically: a larger two-piece floating disc that runs cooler and holds off the fade that creeps into a heavy family SUV through repeated stops.
This is a rear-axle upgrade, not a full overhaul. It pairs sensibly with a front big brake setup or works on its own to firm up pedal feel and restore consistent bite to a Q5 that has covered serious miles. Pad compound is your call, Street, Sport or Racing, so the same hardware suits a daily school-run 8R or one that tows and climbs motorway gradients fully laden.
What this brake kit does for your 2008-2017 Audi Q5 2WD 8R
On the road you notice the difference first in heat tolerance. The two-piece floating disc moves air through its core and sheds temperature faster than a solid OE rear rotor, so the pedal stays firm through a sequence of stops instead of going long. Cutting rotating mass at the rear also takes a small bite out of unsprung weight, which the dampers appreciate over broken surfaces. With three pad compounds on offer, you set the bite to match the car’s life: the Street compound for a refined, low-dust daily 8R, the Sport pad for harder fast-road work, and the Racing compound when the Q5 sees track days or hard, loaded work. Selectable caliper finishes, from the included painted colours through to premium polished and candy options, let the kit read as a deliberate upgrade behind open-spoke wheels rather than an afterthought.
About the Hollow Rear Brake Kit
XYZ Racing’s rear kit is built around a two-piece floating disc, a design that voids material from the rotor body to cut weight without giving up swept area or thermal capacity. The result is a lighter rear disc that still carries enough mass to soak up heat, which counts for more on a heavy SUV than on a light hatch. The caliper is hollow-bodied as standard to keep weight down, with an optional Hollow Racing build for track use that removes the dust cover, is rated to 1000C and carries a two-year warranty. It is a bolt-on rear-axle package matched to the Q5 8R, a pair of left and right rear calipers and discs supplied with braided lines and your chosen pad compound. The three compounds span quiet Street use, through a harder Sport material, to a full Racing compound for sustained heat. 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. The brief is straightforward: lift rear braking performance and consistency above the standard 8R hardware while keeping installation honest.
Fitment for the Audi Q5 (2008-2017)
This kit is specified for the rear axle of the Audi Q5 2WD 8R (TYPE1) across the 2008 to 2017 model run, the first-generation Q5 in its front-wheel-drive form. Confirm your car is the 8R chassis in 2WD spec before ordering, since rear hardware varies across Audi’s SUV range. Caliper colour and pad compound are chosen when you order.

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.
