Caliper render for this kit:

A loaded X5 G05 crests two-and-a-half tonnes once you add passengers, fuel and whatever sits on the tow hitch, and most of that mass rides high on the CLAR platform. The factory rear setup is fine for the school run, but ask it to scrub that weight off from autobahn speeds again and again, or hold the car steady down a long alpine descent, and rear-disc temperatures climb quickly. This is where the XYZ Racing Hollow Rear Brake Kit for the Bmw X5 G05 (2018-2026) earns its place.
It is a rear-axle upgrade built around two-piece discs with a hollow-vane braking ring that cuts rotating and unsprung mass while opening up thermal capacity. Supplied as a matched left-and-right pair, with a choice of pad compounds and a larger, better-ventilated disc, it gives the back axle the heat headroom a heavy 2018-2026 X5 needs when its full kerb weight, and then some, is working against the brakes.
What this rear brake kit does for your 2018-2026 Bmw X5 G05
After fitting, the first thing you notice is a firmer, more progressive pedal that does not go long after three or four hard stops. The bigger rear disc spreads heat over more metal, so the rear axle keeps contributing under repeated heavy braking instead of fading and shoving all the work onto the front. Hollow-vane disc construction and the lighter two-piece design trim rotating and unsprung mass at each rear corner, which sharpens how the back of the car settles over bumps and reduces the gyroscopic inertia the dampers have to fight. With Street, Sport and Racing pad compounds offered, you match bite and temperature range to how the X5 actually gets used, from quiet low-dust towing duty to harder fast-road work, and matching the rear compound to the front keeps the brake balance honest.
About the Hollow rear brake kit
The kit replaces the rear discs and calipers as a matched pair, engineered specifically for the G05 chassis rather than adapted from a generic fitment. The hollow-vane disc design is the headline: coring material out of the braking ring drops weight without surrendering the swept area and venting that a heavy SUV depends on to shed heat, and the two-piece floating bell lets the ring expand without distorting. Three pad compounds are on offer: Street for quiet, low-dust road use, Sport for harder fast-road driving, and Racing for the most demanding heat cycles. The caliper is hollow-bodied as standard, with a Hollow Racing upgrade for serious track use that removes the dust cover, is rated to 1000C and carries a two-year warranty. Calipers come painted in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with premium polished-forged and candy finishes available, so the upgrade reads behind the wheel spokes as clearly as it works. Discs can be drilled or slotted at the same price, braided lines are included, and the centre bell can be upgraded to a two-tone anodized colour or titanium. Every component is sized to clear the G05’s factory wheel diameters.

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.
