Caliper render for this kit:
At over two tonnes before occupants, the E70 X5 asks a great deal of its front brakes. Pulling maximum weight off a motorway exit, or descending an Alpine pass with the kids and luggage aboard, the stock front end is managing thermal loads that standard-size rotors were not designed to sustain repeatedly. The XYZ Racing Hollow front brake kit addresses that thermal ceiling directly, fitting a larger swept area and hollow-vane discs where the original hardware runs out of headroom.
It is a single-axle kit, a matched pair of front calipers and two-piece floating front discs for the left and right corners. The E70 platform, xDrive across the range with engines spanning the 3.0si and 3.0d through to the X5 M, places consistent, heavy demands on the front axle under deceleration. An uprated front kit here does more than shorten stopping distances: it tightens pedal feel, delays the onset of fade, and gives the car’s brake bias somewhere more capable to lean on.
What this brake kit does for your 2006-2013 Bmw X5 E70
The hollow-vane disc routes air through the rotor body to improve heat dissipation over the OEM front discs, reducing the fade that builds during repeated hard stops, the kind that accumulate on mountain descents, towing near capacity or a track day in an SUV that weighs the same as a small van, and the two-piece floating construction lets the disc expand without distorting. Brake balance loads the front axle hardest under heavy deceleration, so it is the right place to add capacity, and dropping rotating and unsprung mass there sharpens turn-in. Three pad compounds, Street, Sport and Racing, let the kit be specced anywhere from school-run-plus-occasional-blast through to dedicated fast-road use. The calipers deliver more consistent clamping force across a wider temperature range, and the larger disc diameter improves mechanical advantage, so the same pedal pressure produces more positive bite. Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone available, so the brake specification aligns with the wider build rather than sitting incongruously behind the front wheels.
About the Hollow Front Brake Kit
The XYZ Racing Hollow front brake kit is a bolt-on front-axle upgrade centred on a hollow-vane disc, a design that prioritises efficient heat evacuation over raw thermal mass, keeping disc temperatures in a more controlled working range across a series of hard stops, paired with a two-piece floating construction. The caliper body is hollow-cast as standard for stiffness without the weight, and a Hollow Racing caliper, with no dust cover, a 1000C rating and a two-year warranty, is available for serious track use. Three pad compounds are available: Street for everyday road use with low dust, Sport for owners who drive with more intent on a regular basis, and Racing for track outings. Included painted caliper finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150 and premium polished-forged Titanium, Polished Gold and Polished Silver plus candy Teal, Blue, Red and Orange. Discs come drilled or slotted at the same price, and centre bells can be two-tone anodized in five colours or titanium. The kit covers the front axle only and is designed for direct fitment to the E70 chassis.
Fitment for the Bmw X5 E70 (2006-2013)
This front brake kit is listed for the BMW X5 E70, covering the full production window from 2006 to 2013. The E70 generation spans a broad engine range, from the 3.0d and 3.0si derivatives through to the high-output X5 M, and the fitment is recorded across that span. Verify brake line routing and caliper bracket clearances against your specific variant and installed wheel size before placing an order.

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.
