Caliper render for this kit:

The E39 5 Series carries its mass like a proper executive saloon, and on a rear-drive car this size the rear axle does more braking work than owners expect, particularly when you are scrubbing motorway speed repeatedly or trail-braking into a long corner. This XYZ Racing rear big brake kit for the BMW 5 Series E39 targets exactly that: heat capacity and pedal consistency at the back of the car.
It is built around two-piece floating discs that shed heat faster than a plain solid casting, a pair of left and right rear calipers you can specify in your own colour, with pads matched to how you actually drive. For a 1995-2003 E39 used hard on road or the occasional track day, that rear thermal headroom is what stops the brakes going soft halfway through a session.
What this big brake kit does for your 1995-2003 BMW 5 Series E39
After fitting, the first thing you notice is a firmer, more repeatable pedal under heavy braking. The two-piece floating disc design pulls heat out of the rotor faster, so the bite stays predictable where the standard setup would already be fading. On a heavy saloon like the E39, that extra rear capacity keeps the car settled under trail-braking instead of leaning entirely on the front axle, holding brake balance front and rear under load. The Racing pad compound copes with sustained hard stops, Sport adds bite for fast-road work, while the Street compound keeps things quiet and clean for daily driving. You can also set the look of the caliper behind the wheel from the included painted finishes, Red, Yellow, Gold, Black and Anodized Black at no cost, with a Custom Color in any Pantone.
About the rear big brake kit
The XYZ Racing rear big brake kit is a bolt-on upgrade for the rear axle of the E39, a pair of left and right rear calipers using two-piece floating discs to grow the working surface and improve heat dissipation versus the original solid rotor. The caliper body is hollow as standard, with a Hollow Racing upgrade for serious track use, no dust cover, rated to 1000C and backed by a two-year warranty. It is offered with three pad compounds, Street, Sport and Racing, so you can spec it for quiet road manners, mixed road-and-track use, or harder track work without swapping the whole setup. The included painted caliper finishes run from Red and Black through Yellow, Gold and Anodized Black, with a Custom Color in any Pantone for owners matching a specific build. Discs come drilled or slotted at the same price, with centre-bell upgrades selectable at checkout. The kit deliberately addresses the rear of the car, which is where a heavy rear-drive 5 Series builds heat under repeated braking and where the factory components lose consistency first.
Fitment for the BMW 5 Series E39 (1995-2003)
This kit is matched to the BMW 5 Series E39 chassis across the full 1995-2003 production run and fits the rear axle. Confirm your exact variant and rear wheel clearance against the spec before ordering, since caliper packaging at the back can vary with wheel choice.

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.
