Fits Bmw I8 (2014-2026)

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 I8 (2014-2026) — 380 mm
380 mm

BMW built the i8 around energy recovery, so its regenerative system soaks up a large share of everyday deceleration before the friction brakes ever come into play. That made sense for efficiency, but it also meant the factory front hardware was specified conservatively for a car that runs to 155 mph. Lean on the i8 down a mountain pass or commit to an evening on circuit, and the standard front brakes start to feel underspecified for everything else the chassis can do.

This XYZ Racing front brake kit for the BMW i8 (2014-2026) closes that gap. It is a single-axle kit: a matched pair of front calipers and two-piece floating discs, left and right, sized for the i8’s front wheels. Three pad compounds, a wide choice of caliper finishes, and braided lines give owners a genuine performance step up that also looks the part behind those 20-inch wheels.

What this brake kit does for your 2014-2026 BMW i8

The hollow-vane disc cuts rotating and unsprung mass at the front axle, the same axle that handles drive from the i8’s electric motor as well as braking loads. Less mass to spin up and slow down means quicker response, better heat management through repeated hard stops, and steadier pedal feel as the discs work harder. The two-piece floating construction lets the disc ring expand under heat without distorting against the bell, which is what keeps the bite consistent lap after lap.

Pad choice is where you tune the kit to how you actually drive. Street is the default: a quiet, low-dust road compound that behaves on the daily commute. Sport adds bite and heat range for fast road work and the occasional track day. Racing is a full circuit compound for owners who spend real time at temperature and care more about sustained friction than gentle cold bite. Braided lines come as part of the kit, firming up the pedal by removing the flex of rubber hoses under pressure.

About the Hollow Front Brake Kit

The caliper is hollow-bodied as standard, which trims weight without giving up stiffness. For serious track use there is an optional Hollow Racing upgrade that drops the dust cover, is rated to 1000C and carries a two-year warranty.

Finishes are broad. The included painted colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, and any Pantone code can be matched as a Custom Color for an upgrade. Above that sit the premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) and the candy range (Candy Teal, Candy Blue, Candy Red, Candy Orange) for owners who want the calipers to be a feature rather than a detail. Discs come drilled or slotted at the same price, and the centre bell can be upgraded to a two-tone anodized finish in five colours, or to titanium. You choose your spec when you order.

Fitment for the BMW i8 (2014-2026)

This kit is catalogued for the BMW i8 from 2014 through 2026, covering both Coupe and Roadster body styles, and fits the front axle as a pair. The i8 runs 20-inch wheels front and rear in its standard staggered setup, so confirm caliper-to-wheel clearance against your exact wheel spec before ordering, especially if you are running aftermarket wheels with tighter spoke clearance.

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.
