Caliper render for this kit:

The E65-generation 7 Series carries the better part of two tonnes, and most of that mass rides on a long wheelbase that loads the rear axle hard every time the car is hauled down from speed. The XYZ Racing Hollow Rear Brake Kit for the Bmw 7 Series E 65 730 (Euro Spec) addresses exactly that weakness: a rear big brake setup that adds thermal capacity and bite where the standard 730 rear discs begin to fade.
This is the rear half of a serious stopping upgrade for a saloon that was never built light. The hollow-vane disc design trims rotational mass, the larger swept area resists heat soak on long motorway descents and repeated heavy stops, and three pad compounds let you match the kit to road, fast-road or harder track-biased use.
What this brake kit does for your 2004-2008 Bmw 7 Series E 65 730 (Euro Spec)
On a car this heavy, rear brake performance is about controlling heat and keeping the pedal consistent once the discs are working hard. The hollow-vane discs shed weight from the rotating assembly, which sharpens response and eases the load the rear suspension has to manage. The two-piece floating construction lets each disc grow under heat without distorting, so the pedal stays firm across consecutive stops while the rear axle keeps contributing instead of cooking and washing out. Three pad compounds set the friction level to suit how the 730 is actually used: the Street compound for quiet, low-dust daily motorway miles, the Sport compound for sharper bite and a wider heat range on spirited drives and the odd track day, and the Racing compound when the car runs hard on circuit. Caliper finishes let the hardware look the part behind the wheel.
About the Hollow Rear Brake Kit
The Hollow Rear Brake Kit pairs an oversized two-piece rear disc with a matched calliper to lift both thermal mass and clamping force over the factory 730 rear setup. The hollow-vane construction removes material to reduce unsprung and rotating weight without sacrificing the larger diameter that does the heat work, and the cooling vanes give the disc somewhere to dump the energy a 1.9-tonne car generates under hard use. The kit ships as a left-and-right rear pair with braided lines and the brackets to bolt onto the E65 rear hub, and is offered with three pad compounds: Street for quiet road use, Sport for a firmer fast-road bite, and Racing for sustained track temperatures. The caliper is a hollow-body unit as standard, with an optional Hollow Racing version rated to 1000C and carrying a two-year warranty for circuit cars. Included painted colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost; a Custom Color in any Pantone is available, with premium polished-forged and candy finishes above that. Discs come drilled or slotted at the same price, and two-tone anodized or titanium centre bells are selectable when you order.

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.
