Fits Bmw 7 SERIES G70 (2022-2026)

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 — Bmw 7 SERIES G70 (2022-2026) — 380 mm
380 mm

The G70-generation 7 Series is the largest and heaviest car ever to wear the badge, with the electric i7 variants nudging 2.6 tonnes and the petrol 760i carrying real mass at autobahn speed. All of that weight has to be hauled down repeatedly, and the factory rear setup is sized for refinement first. The XYZ Racing Hollow Rear Brake Kit for the BMW 7 Series G70 addresses the rear axle specifically, where a heavy limousine loses stability if the back brakes fade before the fronts.

This is a rear-axle upgrade built around a hollow-vane two-piece disc and a fixed caliper, with pad compound and caliper colour chosen to suit how the car is actually used. On a saloon this size, rear braking is about composure under load rather than lap times, and that is where the kit earns its place.

What this brake kit does for your 2022-2026 BMW 7 Series G70

On a car as heavy as the G70, the rear axle does more braking work than most owners assume, particularly during repeated high-speed slowdowns where heat builds quickly. The hollow-vane discs cut rotating mass and shed heat fast, and their two-piece floating build lets them expand without warping, so pedal feel stays consistent as temperatures rise. The fixed caliper clamps more evenly than a sliding rear unit, which tightens the brake balance and keeps the long body settled as you wash off speed from a cruise. Choose the Street pad for quiet, low-dust daily driving, the Sport compound for firmer bite and a wider heat range on a fast B-road, or the Racing compound if the car sees serious high-speed work. The result is a rear end that resists fade and holds the 7 Series straight under hard braking.

About the Hollow rear brake kit

The Hollow name refers to the disc’s internal vanes: material is removed from the centre of the two-piece disc to shave rotating and unsprung weight without surrendering the swept area that does the work. That matters on a big-wheeled saloon, where every kilo of rotating mass blunts response. The kit pairs a matched left-and-right pair of those discs with a fixed multi-piston caliper for even clamping force, braided lines, and three pad compounds, Street, Sport and Racing, so the bite can be matched to how the car is driven. The caliper is a hollow-body unit as standard, with an optional Hollow Racing version rated to 1000C and a two-year warranty for hard high-speed and track use. Included painted finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone and premium polished-forged and candy options above that, visible behind the large open-spoke wheels these cars typically run. Discs are offered drilled or slotted at the same price, and two-tone anodized or titanium centre bells are selectable. It is a bolt-on rear package built to raise braking capacity without altering the car’s fundamental ride character.

Fitment for the BMW 7 Series G70 (2022-2026)

This kit is built for the G70 7 Series across the 2022 to 2026 model years, covering the petrol, hybrid and i7 electric variants that share the chassis. It fits the rear axle only. Confirm your exact build and wheel size before ordering, as the larger disc requires adequate caliper clearance.

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.
