Caliper render for this kit:

The E91 Touring in xDrive spec brings a particular challenge to a brake upgrade: the combination of 4WD hardware, the estate body’s kerb weight, and the way the xDrive torque-split operates means the front discs carry a higher sustained thermal load than on the equivalent rear-wheel-drive 325i or 330i saloon. Drivers who use their Touring as it was built to be used, fast, loaded, and across varied terrain, will find the stock setup running out of confidence before the chassis does.
This front big brake kit from XYZ Racing addresses the front axle directly. It is a single-axle upgrade, a matched pair of front calipers and discs, with three pad compounds spanning road default through to full racing specification.
What this brake kit does for your 2006-2012 Bmw 3 SERIES E 91 4WD
With the xDrive system driving torque through the front axle as well as the rear, the front brakes on the E91 4WD work against both rotational inertia and the drivetrain’s resistance under hard deceleration. A higher-specification front setup with improved thermal capacity changes the character of the car at its limits: the pedal stays consistent rather than going progressively soft when the discs have been repeatedly loaded on an extended fast-road run or track session.
Sport-compound pads deliver improved cold-bite and fade resistance over the Street default without requiring the elevated operating temperature of a Racing compound, making them practical for year-round use in a car that may be covering a motorway at 70mph one hour and attacking a mountain pass the next. Racing compound carries a bedding-in requirement and a warm-up window, but is the correct choice when the E91 xDrive’s traction advantage is being exploited at full circuit pace. Two-piece floating discs with an aluminium centre bell reduce rotating mass and expand cleanly under heat, while hollow-vane internals keep the disc body cool through repeated stops.
About the Hollow Front Brake Kit
The XYZ Racing caliper is built on a hollow body as standard, a direct front-axle upgrade over standard BMW equipment. Pad compound choice spans three grades: Street for a quiet, low-dust road feel on upgraded materials, Sport for improved fade resistance and heat range without committing to a race setup, and Racing for circuit use where thermal performance across repeated hard stops is the priority.
Caliper finish runs across painted-at-no-cost colours of Red, Yellow, Gold, Black, and Anodized Black, with Custom Color matching any Pantone for £150 and premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) available, letting buyers match the installation to their alloy and bodywork combination rather than accepting a default. Discs come drilled or slotted at the same price, and the centre bell can be two-tone in five anodized colours or titanium. The Hollow Racing caliper upgrade (no dust cover, rated 1000C, two-year warranty) and braided lines are there for serious circuit use. The front-specific fitment retains the standard rear brake setup, concentrating the upgrade on the axle most affected by the xDrive’s weight distribution and torque demands.
Fitment for the Bmw 3 SERIES E 91 4WD (2006-2012)
This kit is built for the BMW 3 Series E91 Touring in xDrive (4WD) specification, covering model years 2006 to 2012. Confirm your car carries the xDrive designation before ordering, as the front brake hardware and hub specification on the 4WD E91 differs from the rear-wheel-drive E91 Touring variants produced over the same period.

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.
