Caliper render for this kit:
The G70 7 Series is one of the heaviest production BMWs ever built. The M760e xDrive comes in at nearly 2,400 kg, and the i7 variants push close to 2,700 kg in their heavier configurations. BMW’s standard brakes handle everyday motoring competently, refined, quiet, and well-matched to the ABS calibration, but they were not sized for sustained hard use: repeated late braking from motorway speeds, the back-to-back stops of an alpine pass, or the thermal stress of a track day in something that weighs as much as a laden Transit.
The XYZ Racing Hollow front brake kit for the BMW 7 Series G70 addresses the thermal ceiling directly. It is a single-axle front kit, a matched pair of front calipers and two-piece floating front discs for the left and right corners. The hollow-vane rotors shed mass without reducing the disc’s ability to absorb heat, and three pad compounds, Street, Sport and Racing, mean the specification can be matched to how hard the car is actually driven.
What this brake kit does for your 2022-2026 Bmw 7 SERIES G70
On a car this heavy, brake fade arrives quickly once the discs are saturated. The hollow rotor construction gives heat a better path out, keeping fluid temperatures lower across repeated hard stops, and the two-piece floating disc expands cleanly under load to keep the pad in flat contact. The larger disc swept area that defines this as a big brake kit adds initial bite over the standard setup, noticeable at the pedal and reflected in shorter stopping distances when the car is being pushed hard. Brake balance loads the front axle hardest under heavy deceleration, so that is where the extra capacity lands, and shedding rotating and unsprung mass at the front sharpens response on the way in. Included painted caliper finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone available; through the G70’s typically generous wheel apertures the colour reads clearly.
About the Hollow Front Brake Kit
XYZ Racing’s Hollow front brake kit replaces the front rotors and calipers with a big-brake assembly built around hollow-vane discs and a two-piece floating construction. The hollow internal vanes are the defining technical choice: less rotor mass reduces the rotational inertia each front corner carries through direction changes, and the open internal geometry routes airflow to carry heat away more aggressively than a conventional solid or vented disc. 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 cover the spectrum: Street is the quiet, low-dust road default, Sport steps up for fast-road driving where braking events are harder and more frequent, and Racing is the compound for elevated rotor temperatures. Included painted 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. The kit is designed for front-axle fitment on the G70 platform.
Fitment for the Bmw 7 SERIES G70 (2022-2026)
This kit is catalogued for the BMW 7 Series G70 platform, covering 2022 to 2026 across the petrol, plug-in hybrid and electric variants in the range. Confirm your current front rotor diameter and caliper carrier spacing before ordering, as brake architecture within the G70 range can differ between standard and M Sport specification cars on the same chassis code.

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.
