Caliper render for this kit:
The G05 X5’s kerb weight tells its own story. Even the base xDrive40i crosses two tonnes on the scales; the M50i and the X5 M Competition add considerably more. Standard front brakes do the job in everyday use, but thermal mass builds quickly on a twisty descent, a fast B-road or a track day, and once heat is in the discs, pedal feel begins to drift in ways that demand your full attention. The XYZ Racing Hollow front brake kit addresses that directly.
It is a single-axle kit, a matched pair of front calipers and two-piece floating front discs for the left and right corners. The hollow-vane disc runs airflow through the rotor body from the bell outward, shedding heat faster than a solid disc and holding stable braking temperatures under the kind of repeated applications a heavy, powerful SUV demands. Three pad compounds, Street, Sport and Racing, let the buyer choose the operating window that matches how the car is used, from daily commuting through fast-road driving to circuit sessions.
What this brake kit does for your 2018-2026 Bmw X5 G05
The G05 platform places a lot of car over the front axle under braking: the nose drops, weight loads the fronts hard, and sustained high-speed driving exposes the limits of factory discs quickly. Brake balance only loads the front harder the more speed you scrub. The hollow-vane disc handles that thermal load through internal venting that keeps working even as temperatures climb, while the two-piece floating construction lets the disc expand without distorting to keep the pad in flat contact. Consistent pedal feel follows from stable disc temperatures; the driver reads confidence rather than the gradual softening of an overheated disc, and shedding rotating and unsprung mass at the front sharpens response. The Sport compound widens the heat range and bite over Street for fast-road work, with Racing carrying the system to circuit temperatures. Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone available, allowing the hardware to make a visual statement through the X5 G05’s large-diameter alloys, wide enough to put every millimetre of the caliper on show.
About the Hollow Front Brake Kit
The Hollow front brake kit is built around a hollow-vane disc, a design that promotes active airflow through the rotor body to manage temperatures during repeated braking cycles, paired with a two-piece floating construction. The caliper body is hollow-cast as standard, with an optional Hollow Racing caliper, no dust cover, a 1000C rating and a two-year warranty, for serious track use. Three pad compounds define the operating envelope across different use cases: Street is configured for everyday road temperatures with low dust, Sport tolerates the higher sustained temperatures of brisk road driving and occasional spirited use, and Racing operates at its best when the car is working hard and consistently at elevated heat ranges. Included painted caliper finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150 and premium polished-forged Titanium, Polished Gold and Polished Silver plus candy Teal, Blue, Red and Orange. Discs come drilled or slotted at the same price, and centre bells can be two-tone anodized in five colours or titanium. This is a front-axle kit, concentrating on the end of the car that carries the heaviest load in any G05 application.
Fitment for the Bmw X5 G05 (2018-2026)
This kit is configured for the fourth-generation BMW X5, chassis code G05, across the full production run from 2018 to 2026. It covers the front axle and is compatible with the range of G05 drivetrain variants offered during that period.

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 286–380mm (front). 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.
