Caliper render for this kit:
The E61 touring bodyshell carries around 70kg more than the equivalent E60 saloon, and that mass penalty falls directly on the front braking circuit, particularly under the hard stops that fast-road estate owners actually encounter: loaded for a weekend away, overtaking on a dual carriageway, or pushing through an unexpectedly demanding stretch of B-road. XYZ Racing’s Hollow front brake kit is built to handle that front-axle braking demand with uprated two-piece floating discs and a three-way pad compound choice, rather than asking factory-specification discs to cope with work they were never optimised for.
The kit is a single-axle front unit, a left and right pair of calipers on hollow-vane two-piece floating discs that manage heat dispersal more efficiently than the solid-core alternatives on the standard 525, and three pad compounds, Street, Sport, and Racing, mean the same caliper setup serves a daily-driven estate or a spirited track-day car without hardware changes. Set yours at the configurator above.
What this brake kit does for your 2004-2010 Bmw 5 Series E 61 525
The E61’s weight, heavier still in all-wheel-drive 525xi configuration, demands a front braking circuit that can sustain bite across successive hard stops, not just the first one. The hollow-vane disc pulls heat away from the swept surface more effectively than an equivalent solid unit, which translates into consistent pedal feel under the kind of back-to-back braking a loaded touring car produces on a long motorway run or a circuit induction day, while the floating ring expands without coning and the lighter assembly trims unsprung and rotating mass. The three compounds work across genuine use cases: Street is the quiet, low-dust choice for cars spending the majority of their lives on road; Sport gives sharper bite and a wider heat range for fast roads; Racing delivers fade resistance under sustained high-temperature loads on circuit. Caliper colour options, from the included no-cost painted finishes through to premium polished and candy choices, let the upgrade read as considered when viewed through an open-spoke alloy.
About the Hollow Brake Kit
XYZ Racing’s Hollow brake kit takes its designation from the hollow-bodied caliper, fitted as standard, and the hollow-vane two-piece floating disc, a combination that prioritises thermal management across the front axle. Where a standard OEM-spec rotor on an early-2000s BMW estate runs warm under repeated threshold stops, the hollow-vane geometry creates internal airflow paths that carry heat away from the friction surface more continuously, and the floating mounting lets the ring grow without distorting. For hard, sustained circuit use the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C, and carries a two-year warranty. Three pad compounds are built into the product configuration from the outset, Street, Sport, and Racing, covering the span from daily driving to circuit use in a single kit. 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 finish is specified at order from the included Red, Yellow, Gold, Black, and Anodized Black, a Custom Color in any Pantone, premium polished Titanium, Polished Gold, and Polished Silver, and candy Teal, Blue, Red, and Orange, making the kit adaptable to wider build aesthetics rather than locking buyers into a single visual statement. The front-only fitment reflects where the braking effort concentrates on a nose-heavy estate under hard deceleration.
Fitment for the Bmw 5 SERIES E 61 525 (2004-2010)
This kit is specified for the E61 touring in 525 form, covering the full 2004-2010 production span, encompassing both the M54-engined 525i from the early E61 run and the N52-powered variant that succeeded it from 2005. Confirm your drivetrain specification (525i or 525xi) and build date when selecting compound and caliper colour, as front suspension geometry differs between the standard and all-wheel-drive variants.

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.
