Fits Audi A5 8T SPORTBACK 2WD (TYPE I) (2011-2016)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Rear Brake Kit — Audi A5 8T SPORTBACK 2WD (TYPE I) (2011-2016) — 356 mm
356 mm

On the 2WD A5 8T Sportback the longitudinal engine hangs ahead of the front axle, throwing the static weight forward and leaving the rear axle lightly loaded under braking. Audi sized the factory rear discs for that reality. They are modest, and on a hard-driven car they spend their life being dragged along by the fronts rather than doing real work. This XYZ Racing Hollow Rear Brake Kit rebalances that picture, giving the back axle the thermal capacity and bite to actually contribute when you are braking late and repeatedly.

The kit is a rear-axle upgrade for the front-drive (type I) A5 Sportback built from 2011 to 2016. It is the right pick when the fronts have already been uprated, or simply at track-day pace, and the standard rears have started to feel overwhelmed with a long pedal, the smell of hot pads and inconsistent release.

What this brake kit does for your 2011-2016 Audi A5 8T Sportback 2WD (type I)

The larger rear discs add surface area exactly where the B8 platform is short of it, so heat is shed faster between stops and the pedal stays firm through a session rather than going soft. The two-piece floating disc trims rotating and unsprung weight at the rear, which the rear dampers feel as quicker recovery over kerbs and broken surfaces. Three pad compounds let you match the rear bite to how the car is used: Street for quiet, low-dust commuting, Sport for harder fast-road driving, and Racing for repeat braking zones. The result is a more honest brake balance, with the back axle helping slow the car instead of just following the front.

About the Hollow Rear Brake Kit

The rear brake kit pairs an enlarged rear rotor with a bolt-on caliper to lift the rear axle’s braking capacity well beyond the OE setup. The two-piece floating disc reduces mass without sacrificing the disc face area you need for heat management. The caliper is hollow-bodied as standard to keep weight down, with an optional Hollow Racing build for circuit use that removes the dust cover, is rated to 1000C and carries a two-year warranty. Pad compound is chosen when you order: Street for road use, Sport for fast-road and spirited driving, Racing for circuit work, so the same hardware suits very different drivers. 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, all visible behind the wheel spokes.

Fitment for the Audi A5 8T Sportback 2WD (type I) (2011-2016)

This kit fits the 2WD (type I) A5 8T Sportback across the 2011 to 2016 model years. It is the rear-axle application; confirm your chassis is the front-drive variant before ordering, as the 2WD rear hub differs from the quattro setup.

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.
