Fits Bmw Z4 E89 35I (2009-2016)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Front Brake Kit — Bmw Z4 E89 35I (2009-2016) — 330 mm
330 mm

The E89 Z4 35i carries its twin-turbocharged straight-six well ahead of the front axle, yet BMW’s engineers managed something close to 50:50 weight distribution by packing the retractable hardtop mechanism into the tail. That near-even balance is one of the E89’s best qualities; it means the front axle carries exactly its proportionate share of braking duty at every corner entry. It also means that when the front brakes fade, the car’s composure goes with them. The XYZ Racing front big brake kit is built to prevent that.

Running over 300bhp through the rear wheels in a car that tips the scales above 1,400kg, the 35i’s standard front brakes are adequate for road driving and not much beyond it. This kit replaces the front-end hardware, a matched pair of calipers and two-piece floating discs, with components designed for sustained work at higher speeds and higher temperatures.

What this brake kit does for your 2009-2016 Bmw Z4 E89 35I

The kit offers three selectable pad compounds, Street, Sport and Racing, which means one set of hardware can be specced for daily use, spirited fast-road driving, or a full day at Cadwell or Oulton Park without a rebuild between sessions. Street stays quiet and low-dust for the commute, Sport adds bite and heat range for hard road and light track work, and Racing holds up under repeated heavy corner entries where heat soak in the standard system becomes the limiting factor. The two-piece floating discs evacuate heat fast and resist the thermal distortion that softens pedal feel, while braided stainless lines keep the pedal firm as fluid warms. Because the E89 carries a genuine share of stopping force at the front given its balanced weight split, sorting the front brakes has a direct effect on how the car turns in: cleaner deceleration produces more predictable weight transfer onto the front tyres, and that translates to confidence through the apex. The included caliper colours, Red, Yellow, Gold, Black and Anodized Black, are visible through most alloy designs on the E89’s standard 18-inch fitment.

About the Hollow brake kit

XYZ Racing’s series is a front-axle pair designed for cars regularly used outside the standard road-driving envelope. Three pad compounds make the kit adaptable without component changes: Street covers everyday road use, Sport steps up fade resistance and initial bite for faster roads, and Racing handles repeated hard corner entries. The calipers are hollow-body as standard to keep mass off the corner, with the Hollow Racing caliper available as an upgrade for serious track use, no dust cover, rated to 1000C and carrying a two-year warranty. Disc faces come drilled or slotted at the same price. Caliper colour is customer-selected; the painted finishes are no extra cost, Custom Color matches any Pantone for a set fee, and premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) are offered, a detail that matters on a roadster where the front wheels are always on show. Two-tone centre bells in five anodized colours, or titanium, are selectable at checkout.

Fitment for the Bmw Z4 E89 35I (2009-2016)

This brake kit is listed specifically for the BMW Z4 in E89 body style, 35i specification, across the full production run from 2009 to 2016. The E89 is the retractable hardtop roadster; confirm your chassis code to distinguish it from the earlier E85 and E86 coupe and roadster generation. Both the early N54-engined cars produced from 2009 and the later N55 variants fall within this fitment span.

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.
