Fits Bmw 7 SERIES E 66 745 (EURO SPEC) (2002-2006)

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.

Stopping the long-wheelbase E66 745 is a thermal problem before it is anything else. With the N62 4.4-litre V8 hauling a kerb weight north of two tonnes, the rear axle does quieter work than the front but still has to manage real heat and real load every time you scrub off speed from a motorway cruise. The XYZ Racing Hollow Rear Brake Kit for the Bmw 7 Series E 66 745 (euro Spec) addresses that directly, with hollow-vane two-piece discs that shed mass and run cooler than the standard rear setup.

This is a rear-axle upgrade aimed at restoring brake confidence to a heavy, fast luxury saloon rather than chasing lap times. Paired with a matching front kit it sharpens overall pedal feel; on its own it firms up the back of the car and gives the rear discs a fighting chance under repeated heavy use.

What this brake kit does for your 2002-2006 Bmw 7 Series E 66 745 (euro Spec)

Once fitted, the change you notice first is consistency. The hollow-vane discs carry less rotating mass than the factory rears, so they come up to temperature predictably and shed heat faster when you string several hard stops together coming off a derestricted road, and the two-piece floating build keeps each disc true as it heats. The choice of Street, Sport and Racing pad compounds lets you match the rear axle to how you actually drive the 745: quiet, low-dust and progressive for daily mileage with the Street pad, a firmer bite and wider heat range with the Sport pad when the car is loaded and using the full reach of the V8, and the Racing compound for the hardest thermal duty. Removing rotating mass at each rear corner also takes a small load off the air-sprung rear suspension. With a full range of caliper finishes, including a custom option, the hardware looks deliberate behind the factory or aftermarket wheels rather than an afterthought.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit takes its name from its hollow-vane disc, whose internal structure is hollowed to cut weight while keeping the swept area that does the work. On a car as heavy as the E66, that matters more than it would on a lightweight coupe: every kilo of rotating mass removed from the rear axle is mass the brakes, suspension and drivetrain no longer have to fight. The kit pairs a matched left-and-right pair of two-piece discs with uprated calipers, braided lines and three pad compounds, Street for quiet, low-dust daily use, Sport for a sharper road bite and a wider heat range, and Racing for the hardest thermal duty. 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 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. Discs come drilled or slotted at the same price, and two-tone anodized or titanium centre bells are selectable. It is engineered as a bolt-on rear-axle upgrade for the 745 specifically, so disc diameter and caliper mounting suit this chassis rather than a universal fit.

Fitment for the Bmw 7 Series E 66 745 (euro Spec) (2002-2006)

This kit is cut for the Euro-spec Bmw 7 Series E 66 745 built from 2002 to 2006, the long-wheelbase E66 bodyshell with the N62 4.4-litre V8. It covers the rear axle only. Confirm your chassis code and build year against the listing before ordering, and pair with the matching front kit if you want a balanced upgrade front to rear.

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.
