Caliper render for this kit:
The E30 318 sat at the base of BMW’s third-generation 3 Series hierarchy, and its braking specification reflected that position. Where the 323i and 325i received vented front discs as standard, the 318 ran solid rotors, adequate alongside the M10 or M40’s output on the road but a setup that reveals its ceiling quickly when the car is used with intent. That matters because the E30, even in 318 guise, is a properly sorted rear-wheel-drive chassis, balanced and responsive to driver input in a way that puts the front brakes under real scrutiny the moment the road tightens.
The XYZ Racing front big brake kit answers that gap directly with a single front-axle kit: a matched pair of calipers and two-piece floating discs sized to what the E30 is capable of, not to the specification its base engine demanded.
What this brake kit does for your 1982-1991 Bmw 3 SERIES E 30 318
Replacing the stock solid front rotors with the XYZ Racing two-piece floating discs reduces heat soak at the caliper and delivers a firmer, more consistent pedal across consecutive hard stops, the kind of gain that matters most on a rear-drive car where front braking load and weight transfer at turn-in happen together. The hollow-vane disc moves cooling air through the rotor body, and the floating ring expands under heat without coning. Cutting rotating and unsprung mass at the front axle also benefits a chassis this light.
Pad compound matches how the car is actually used, chosen when you order: Street for a 318 in everyday or road-focused ownership, Sport for mixed use with spirited and occasional track driving, and Racing for a car that sees genuine lap sessions. 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, keeping the hardware looking considered rather than accidental on a car that still draws a crowd at any 1980s BMW gathering.
About the Hollow Front Brake Kit
The caliper runs a hollow body as standard, holding reciprocating weight down and matched to the E30’s front axle to avoid the clearance complications that arise from fitting hardware specified for a larger platform onto a car built around the 318’s compact brake architecture. Compound is committed at order stage, so be clear on how the car splits its time: Racing needs sustained heat to perform and returns mediocre results in cold or low-speed road conditions. For circuit cars, a Hollow Racing upgrade removes the dust cover, is rated to 1000C and carries a two-year warranty. Premium polished-forged and candy caliper finishes, along with two-tone or titanium centre bells, are selectable at checkout.
Fitment for the Bmw 3 SERIES E 30 318 (1982-1991)
Coverage runs the full BMW 3 Series E30 318 production window from 1982 to 1991, taking in the early M10-engined cars and the M40 and M42 variants that followed from 1987. If the car’s front brake hardware has been modified previously, with different calipers, alternative hubs or spacers fitted, verify the front geometry still matches standard 318 specification before ordering.

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.
