Caliper render for this kit:

The E30 325’s front axle carries the bulk of braking load under heavy deceleration, and four decades of motorsport use have made plain that the factory hardware, designed when track-day culture barely existed, was never specced for repeated hard stops. The XYZ Racing front big brake kit brings the front braking system up to what a 325 used in anger actually demands. It is a single front-axle kit: a matched pair of calipers and two-piece floating discs.
The 325 rewards late braking and stable corner entry, qualities that rest entirely on what is happening at the front corners when you are trail-braking deep into a hairpin or holding a tight line at the limit of grip. Getting that right is less about the engine and more about a front brake setup that does not fade through a session.
What this brake kit does for your 1982-1991 BMW 3 Series E30 325
The hollow-vane disc manages heat more aggressively than a solid alternative, which matters directly on an E30 asked to scrub speed repeatedly without a full cool-down between runs. The two-piece floating ring grows under heat without coning and trims rotating and unsprung mass at the front axle. Owners who run the 325 hard on circuit know the factory setup fades progressively through a long session; the XYZ Racing kit addresses that at the point where fade begins.
Pad compound covers the spectrum from occasional spirited road use to dedicated competition and is chosen when you order. Street suits road-biased driving, Sport adds bite and heat range for mixed and track-day use, and Racing is built for sessions where the brakes repeatedly reach the upper end of their operating range. Braided lines firm the pedal and discs come drilled or slotted at the same price. Caliper colour is included across Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150, completing a kit that works mechanically and visually with the build.
About the Hollow Front Brake Kit
The caliper runs a hollow body as standard, prioritising low weight and quick heat shedding across sustained hard use, a relevant choice for a car now primarily built for track days, sprint events and hillclimbs rather than the motorway runs it was engineered around in 1982. The kit targets the front axle of the BMW 3 Series E30 325, where braking forces under nose-down weight transfer are highest.
Pad compound spans three grades: Street for road-biased use, Sport for mixed driving with track exposure, and Racing for sessions where the brakes will repeatedly reach the upper end of their range. For dedicated circuit work a Hollow Racing upgrade drops the dust cover, is rated to 1000C and carries a two-year warranty. Beyond the included painted colours, premium polished-forged finishes in Titanium, Polished Gold and Polished Silver and candy finishes in Teal, Blue, Red and Orange are available, along with two-tone or titanium centre bells, all selectable at checkout to suit a period-correct restoration or a committed competition build.
Fitment for the BMW 3 Series E30 325 (1982-1991)
This front brake kit covers the BMW 3 Series E30 in 325 trim across the complete production run from 1982 to 1991, encompassing both the economy-oriented 325e (eta) and the more sporting 325i variants. The kit addresses the front axle only; a matched rear upgrade can be specified separately if building a balanced system across both axles.

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.
