Fits Audi Q5 2WD (FY) (2017-2026)

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 Q5 2WD (FY) (2017-2026) — 356 mm
356 mm

The second-generation FY Q5 is a heavy machine, the better part of 1.8 tonnes before you add passengers and luggage, and in 2WD front-drive form most of that weight sits over the nose. The rear brakes do the quieter share of the work, right up until you point a fully loaded Q5 down a long descent or hitch a trailer to the back, at which point rear thermal capacity stops being academic. The XYZ Racing Hollow Rear Brake Kit for the Audi Q5 2WD (FY) is built for exactly that duty.

This is a rear-axle upgrade aimed at the fast-road and heavy-use Q5 owner rather than the dedicated track crowd. It is a pair of rear calipers and two-piece floating discs that resist the heat soak a standard sliding setup struggles with. The result is a firmer, more progressive pedal that keeps its character when the brakes are hot instead of going long and vague.

What this big brake kit does for your 2017-2026 Audi Q5 2WD (FY)

Fit the kit and the first thing you notice is pedal consistency under repeated stops. The hollow-vane disc sheds heat faster and carries less rotating mass than the OE rear rotor, so the rear axle recovers between brake applications instead of cooking. On a 2WD Q5 that lives on motorways, school runs and the occasional loaded weekend away, that means a brake you can lean on through long descents and when towing near the limit. Three pad compounds let you match the rear bias to how you actually drive: Street for quiet, low-dust road use, Sport for fast-road work and the occasional track day, and Racing when the car sees serious circuit time. Behind a set of larger aftermarket wheels the kit fills the arch properly, with included caliper colours of Red, Yellow, Gold, Black and Anodized Black at no extra cost, or a custom Pantone shade if you want to match the car exactly.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit pairs a two-piece floating disc with a forged caliper that is hollow-bodied as standard, keeping weight down while clamping the disc evenly across the pad rather than relying on a single sliding piston. That even clamp is what gives the kit its more linear, repeatable bite. Lower rotating and unsprung mass at the rear sharpens how the Q5 settles under braking and helps the dampers keep the rear tyres planted. Braided lines are included for a firm pedal that does not balloon as the fluid warms. XYZ Racing supplies it as a rear-specific package, a pair of rear calipers and discs, so it pairs naturally with a front big brake upgrade for balanced braking front and rear, or stands alone where the priority is rear thermal headroom and pad choice. Discs can be drilled or slotted at the same price, and the centre bell can be upgraded to a two-tone anodized finish in five colours or to titanium when you order.

Fitment for the Audi Q5 2WD (FY) (2017-2026)

This kit is cut specifically for the FY-chassis Audi Q5 in 2WD front-drive form, covering the 2017 to 2026 model years, and fits the rear axle only. Confirm your car is the 2WD (FY) variant and falls within that year span before you order, as the drivetrain designation matters for correct fitment.

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.
