Caliper render for this kit:
The E63’s defining challenge has always been mass. Even in 645Ci or 650i specification, the 6 Series coupé carries enough weight to generate serious thermal load on its front brakes through the fast B-road and mountain-pass driving these cars were made for. In M6 specification, with the S85 V10’s 507bhp available on demand and a chassis that will use every one of them, the demands on that front axle multiply considerably. This XYZ Racing front brake kit addresses what the standard setup was never really asked to handle, fitted as a matched pair of front calipers and discs.
The M6 was BMW’s grand tourer that wanted to be a sports car. It succeeded, and that ambiguity is exactly where the standard brake package runs out of answers. This kit is a front-axle upgrade that can follow the car across its full range, from fast-road daily use to the occasional circuit day any M6 owner eventually considers.
What this brake kit does for your 2003-2010 BMW 6 Series E63 (including M6)
The two-piece floating disc carries a hollow-vane rotor that improves heat evacuation from the friction surface across repeated heavy stops, directly relevant when the E63’s kerbweight is arriving at a braking point from serious speed. Reduced rotating mass at the front also keeps the steering crisp and the brake balance steady under load.
Three pad compounds let you specify precisely how the car is used. Street is the quiet, low-dust default for everyday driving. Sport handles spirited road use with the occasional hard stop and a higher heat range. Racing is the dedicated circuit compound for when brake temperatures climb and stay elevated. Caliper colours start with the no-cost painted options of Red, Yellow, Gold, Black, and Anodized Black. A Custom Color in any Pantone is £150, with premium polished-forged Titanium, Polished Gold, and Polished Silver, or candy Teal, Blue, Red, and Orange, so the install reads alongside the M6’s visual character rather than as an afterthought.
About the Hollow Brake Kit
The kit uses a hollow-vane rotor whose engineered cavity structure between the friction faces accelerates heat movement away from the contact patch more efficiently than a conventional vented disc, which matters most under the sustained braking the E63’s weight demands. The two-piece floating disc comes drilled or slotted at the same price, with braided lines for a firm pedal under heat. The caliper is a hollow-body forged unit as standard, with an optional Hollow Racing upgrade for serious track work that drops the dust cover, is rated to 1000C, and carries a two-year warranty. Centre bell upgrades are available two-tone in five anodized colours or in titanium, all selected when you order.
Fitment for the BMW 6 Series E63 (including M6) (2003-2010)
This kit covers the E63 6 Series coupé across the full 2003 to 2010 production run, with the M6 variant explicitly included. The E63 and its M6 derivative ran different original front brake packages across the range, so confirm your specific variant’s front-axle specification against the kit listing before ordering.

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 286–380mm (front). 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.
