Caliper render for this kit:
The F30 328i’s N20 turbocharged four-cylinder pulls harder than the 2.0-litre badge implies. Torque arrives early and sustains through the mid-range, and in a saloon with the F30’s kerbweight, that delivery puts a real cumulative load on the front brake package. The factory setup is calibrated for mixed road use and does that job adequately, but push the MacPherson strut front axle into a track morning or a sustained fast-road session and the thermal ceiling of a standard disc and a generic factory pad becomes apparent through extended fade.
This XYZ Racing front brake kit addresses that gap directly. It is a single-axle upgrade, a matched pair of front calipers and discs. Two-piece floating discs reduce rotating mass ahead of the front struts while improving heat management through hollow-vane internals that draw air through the disc body. Three pad compounds and a full range of caliper finishes let the system be configured to how the 328i is actually used, not where the factory compromise landed.
What this brake kit does for your 2012-2018 BMW 3 Series F30 328i
The primary gain is fade resistance under sustained load. On a circuit or a fast mountain road where hard-braking zones repeat, the two-piece disc disperses heat faster than a conventional equivalent, keeping pedal feel consistent after repeated heavy applications that would push a standard rotor into its thermal limits. The aluminium centre bell lets the friction ring expand cleanly under heat without distorting. Reducing rotating mass at the front axle also allows the MacPherson struts to react more quickly over surface changes, which sharpens the chassis response the F30 already has in reserve.
The three-compound pad range handles the temperature spectrum properly: Street is the quiet, low-dust compound for cold-start road driving, Sport for high-energy road use where pads see repeated elevated temperatures and need more bite, and Racing for sessions where the brakes will reach and hold operating temperature throughout.
About the Hollow Front Brake Kit
The XYZ Racing caliper is built on a hollow body as standard, and the kit centres on a two-piece floating disc that prioritises heat management through geometry rather than exotic materials. The hollow-vane internals create accelerated airflow through the disc body during braking events, reducing heat-soak and the fade that follows sustained use. Three pad grades are offered: Street for everyday driving across a wide temperature range, Sport for performance road use where brakes are working hard on a regular basis, and Racing for circuit conditions where pads will operate within a defined elevated temperature window throughout a session.
Discs come 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 is painted at no 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) take the look to show grade. The Hollow Racing caliper upgrade (no dust cover, rated 1000C, two-year warranty) and braided lines suit committed track use.
Fitment for the BMW 3 Series F30 328i (2012-2018)
This kit is built for the BMW 3 Series F30 platform in 328i specification, covering production from 2012 through 2018. The F30 designation applies to the saloon body only; the F31 Touring, F32 Coupe, and F34 Gran Turismo share the same generation but carry different chassis codes. Confirm your build date and engine specification before ordering if your car is close to either end of the production window.

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.
