Caliper render for this kit:
The E91 Touring carries more kerb weight than the E90 saloon it shares its underpinnings with, and the 320 arrives from the factory with front brake hardware sized for the sort of driving BMW’s marketing team imagined: motorway commuting, school runs, the occasional spirited B-road. For owners who push harder, with repeated corners at Blyton Park, sustained downhill sections loaded with camping gear, or a genuine track day programme, the standard front setup finds its limit earlier than most expect.
The XYZ Racing front big brake kit for the BMW 3 Series E91 320 covers the 2006 to 2011 production run as a single-axle upgrade: a matched pair of front calipers and discs that bolt to the corners where the Touring’s added mass loads hardest. It is configured at the point of purchase to suit the way you actually drive this car.
What this brake kit does for your 2006-2011 BMW 3 Series E91 320
Two-piece floating discs reduce rotating mass at the front axle, a meaningful change on a platform where the engine sits ahead of the front wheels and the Touring body adds weight over the E90 saloon. The aluminium centre bell lets the friction ring expand under heat without distorting, which keeps the disc face true and the pedal consistent. Hollow-vane internals improve heat transfer across the disc body under repeated hard stops, delaying the fade the OEM hardware can exhibit once the brakes are working consistently.
Three pad compounds let the same kit serve different owners differently. Street is the quiet, low-dust default that performs predictably from cold; Sport raises the operating temperature ceiling and gives more bite under sustained load for fast-road use with the odd track day; Racing is the dedicated circuit compound for an E91 that needs the pad up to temperature before it gives its best.
About the Hollow brake kit
The caliper is built on a hollow body as standard, an approach that keeps rotating and unsprung mass low without compromising stiffness. Unlike drilled or slotted disc faces, which address gas and dust evacuation at the surface, the construction here targets the disc’s thermal and mass properties so the rotor sheds heat evenly under the kind of repeated loading track and fast-road driving impose on the front axle. Discs are offered drilled or slotted at the same price, and the centre bell can be specified two-tone in five anodized colours or in titanium.
Caliper colour comes painted at no extra cost in Red, Yellow, Gold, Black, or Anodized Black. Custom Color matches any Pantone for £150, and premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) are available for owners who want the calipers to stand out behind the spokes. For serious circuit use, the Hollow Racing caliper upgrade runs without a dust cover, is rated to 1000C, and carries a two-year warranty. Braided lines complete the system with a firmer, more consistent pedal.
Fitment for the BMW 3 Series E91 320 (2006-2011)
This kit fits the BMW 3 Series E91, the five-door Touring body, in 320 engine specification across the production span from 2006 to 2011. The E91 body code distinguishes this fitment from the E90 saloon, E92 coupe, and E93 convertible. If you are running one of those body styles or a different engine variant, verify the kit reference separately before ordering, as brake carrier geometry can differ between body codes within the same generation.

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.
