XYZ Racing Hollow Rear Brake Kit — Bmw 7 SERIES G 12 (2015-2026)

The G12-generation 7 Series carries more car behind its rear axle than almost anything else BMW builds, and on a long-wheelbase saloon nudging two tonnes the rear brakes spend their life managing weight transfer rather than headline stopping power. The XYZ Racing Hollow Rear Brake Kit for the Bmw 7 Series G 12 attacks that problem at the back axle, where a heavy luxury saloon most needs help shedding heat on repeated stops.

This is a rear-axle upgrade built around a hollow-vane, weight-saving two-piece disc and a fixed big-brake caliper, sized for a car that asks a lot of its brakes on motorway descents and quick A-road work. It is the rear half of a balanced setup for owners running anything from a 730d to a 750i who want the back of the car to pull its weight under hard retardation.

What this rear brake kit does for your 2015-2026 Bmw 7 Series G 12

Fit the kit and the first thing you notice is a firmer, more confident rear under braking, with less of the soft, settle-back feel that comes from a factory rear setup on a heavy saloon. The hollow-vane disc strips rotating and unsprung mass from each rear corner, which sharpens how quickly the back axle responds and eases the load on the air-sprung rear suspension, while the two-piece floating build keeps each disc true as it heats. With Street, Sport and Racing pad compounds available, you can match bite and heat range to how you actually use the car, from quiet, low-dust commuting to spirited cross-country runs. Bigger, better-cooled rear discs hold their bite through repeated stops, so a long descent with passengers and luggage aboard no longer cooks the rear brakes into a spongy pedal. The result is a 7 Series that stops squarer and stays planted instead of pitching hard onto its nose.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is XYZ Racing’s rear big-brake package, named for the hollow-vane disc design that removes mass from the centre of each disc without surrendering swept area. Lighter discs mean less rotating weight for the rear axle to spin up and slow down, and the internal venting gives heat somewhere to go on a car as heavy as the G12. The kit pairs a matched left-and-right pair of two-piece discs with a fixed big-brake caliper, braided lines and a choice of three pad compounds: Street for everyday, low-dust driving, Sport for harder fast-road use and a wider heat range, and Racing for track and high-load work. The caliper is a hollow-body unit as standard, with an optional Hollow Racing version rated to 1000C and a two-year warranty for serious circuit 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, so the upgrade reads as cleanly through the rear wheels as it performs. Discs come drilled or slotted at the same price, and two-tone anodized or titanium centre bells are selectable. It is engineered as a matched rear-axle component rather than a generic disc swap, which is why fitment is tied to the specific chassis it is listed against.

This kit is listed for the long-wheelbase G12 7 Series across the 2015 to 2026 model years, covering the rear axle specifically. It is sold as a rear-position big brake kit, so pair it with a matching front setup if you want balanced bias front to rear. Confirm your exact chassis code and build year against the listing before ordering so the caliper and disc dimensions line up with your car.
