Caliper render for this kit:

The E91 Touring body carries 60-80kg more than the equivalent E90 saloon, and that extra mass is felt at the front axle every time you are scrubbing speed on a fast B-road or arriving late for a corner on circuit. The 325’s N52 straight-six delivers a usable spread of torque across the rev range, but the factory front brakes were not specced with the Touring’s gross weight or sustained hard-stop use in mind.
This XYZ Racing front big brake kit addresses that shortfall for the E91 325 directly. It is a single-axle upgrade, a matched pair of front calipers and discs, bringing enlarged rotors, better heat management, and three pad compounds so the specification can match the way you actually use the car.
What this brake kit does for your 2006-2011 Bmw 3 SERIES E 91 325
Greater swept area over the standard 325 front discs translates to shorter stopping distances and, critically for a Touring that is regularly loaded, sustained performance once the discs are up to temperature. Two-piece floating disc construction removes weight from the rotating assembly at the front corners, which sharpens steering response on an E91 that can feel nose-heavy when the rear is carrying any real load. The aluminium centre bell lets the friction ring grow under heat without distorting, keeping the disc true through repeated hard stops, while the hollow-vane internals move air through the disc body to keep temperatures in check.
All three compounds are available to configure, so a daily driver, a track-prepared Touring, and a fast-road car with occasional circuit outings all get a workable specification from the same kit. Street is the quiet, low-dust road default; Sport adds bite and heat range for spirited driving with the odd track day; Racing is the dedicated circuit compound.
About the Hollow Front Brake Kit
The XYZ Racing caliper runs a hollow body as standard, shaving mass from the rotating and unsprung assembly where the E91’s heavier platform benefits most, without giving up structural integrity. Three pad compounds are built into the configuration: Street for high-mileage everyday driving, Sport for owners mixing commutes with spirited B-roads, and Racing for track-day temperatures and repeated hard stops where ordinary compounds begin to fade.
Discs come drilled or slotted at the same price, and the centre bell can be upgraded to two-tone in five anodized colours or titanium. The caliper is painted at no extra cost in Red, Yellow, Gold, Black, or Anodized Black; Custom Color covers any Pantone for £150; and premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) take the appearance to show grade. For sustained circuit work, the Hollow Racing caliper upgrade runs without a dust cover, is rated to 1000C, and carries a two-year warranty; braided lines firm the pedal under heat.
Fitment for the Bmw 3 SERIES E 91 325 (2006-2011)
This front big brake kit is specified for the BMW 3 Series E91 chassis in 325 trim across the 2006 to 2011 production run. The E91 is the five-door Touring body variant of the E9x generation. Confirm wheel clearance against your existing alloy before ordering, as the larger caliper and disc dimensions on a big brake kit may require a larger wheel diameter than the standard factory fit.

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.
