Caliper render for this kit:
The 545i occupies a specific space in the E60 5 Series lineup: 333 bhp from the 4.4-litre N62 V8 in a car that tips the scales beyond 1,700 kg kerb. BMW’s factory braking hardware was sized for the car’s standard road brief, motorway cruising and the occasional hard stop, and it handles that competently. Ask the front axle for repeated, high-energy deceleration at speed, whether on a circuit or a fast B-road run, and the limitations of cast-iron OEM discs begin to surface.
The XYZ Racing Hollow Front Brake Kit addresses that specific problem on this specific car. It is a single-axle front kit, a left and right pair of calipers on two-piece floating discs, with a choice of three pad compounds, Street, Sport, or Racing, so the installation works across everything from a refreshed daily driver to a track-day-ready saloon without needing a second set of parts. Set yours at the configurator above.
What this brake kit does for your 2003-2010 Bmw 5 SERIES E 60 545
The E60’s front axle carries a disproportionate share of both the car’s weight and its braking load. That nose-heavy N62 layout means the front brakes are always working harder than the rears. The two-piece floating disc addresses heat build-up directly: the lighter floating construction lowers unsprung and rotating mass at the front corner while the friction ring maintains the swept area and bite the car’s weight demands, and the floating mounting lets that ring expand without coning as temperatures rise. Pedal feel through repeated stops is firmer and more consistent than OEM. Three pad options let you configure the kit for daily commuting on the quiet, low-dust Street compound, enthusiastic road use on the higher-bite Sport pad, or circuit lapping on the Racing compound, with a straight pad swap rather than replacing the disc.
About the Hollow Front Brake Kit
XYZ Racing’s Hollow kit pairs a hollow-bodied caliper, fitted as standard, with a two-piece floating disc, cutting unsprung mass without reducing effective swept area. For sustained track use, the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C, and carries a two-year warranty. The compound selection, Street, Sport, and Racing, spans low-dust quiet daily use through to high-friction track-spec material capable of withstanding repeated heat cycles. Disc style is drilled or slotted at the same price, centre bells upgrade to two-tone anodized in five colours or to titanium at checkout, and caliper finishes run from the included Red, Yellow, Gold, Black, and Anodized Black at no extra cost, through a Custom Color in any Pantone, to premium polished Titanium, Polished Gold, and Polished Silver and candy Teal, Blue, Red, and Orange, making the installation visible through open-spoke wheels without looking conspicuous. The front fitment is sized for the braking load of the E60 platform, where a large, heavy saloon asks considerably more of its front corner than a lighter car of comparable power. The kit covers the front axle only.

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.
