Fits Alfa Romeo 4C (2013-2018)

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 Rear Brake Kit — Alfa Romeo 4C (2013-2018) — 380 mm
380 mm

The 4C’s carbon-fibre monocoque keeps kerb weight close to a tonne, and with the 1.75-litre turbo four mounted behind the cabin a real share of that mass rides over the rear axle. That changes how the back end deals with braking: the rears do more work on a mid-engined Alfa than they ever would on a nose-heavy front-engine coupe, and on a hard track lap they are the discs that heat-soak first.

The XYZ Racing Hollow Rear Brake Kit for the Alfa Romeo 4C is built to take that load. It is a matched pair of left and right rear calipers and two-piece floating discs, with a choice of pad compound, so the back axle keeps biting through repeated stops rather than going long and wooden as the standard setup starts to fade.

What this brake kit does for your 2013-2018 Alfa Romeo 4C

Fit it and the first thing you feel is a firmer, more predictable pedal once the discs are up to temperature. The hollow-vane disc core trims rotating and unsprung mass, which on a light, fast 4C the dampers and unassisted structure feel straight through the wheel over kerbs and quick direction changes.

Pad compound matches the kit to use. Street is the quiet, low-dust default with cold-stop bite for road work. Sport adds heat range for fast road with the odd track day. Racing holds its friction at the heat a light 4C generates on circuit, so the rear stays settled under trail-braking instead of stepping out as the pads cook. Either way you get steadier rear-end behaviour on the 4C’s unassisted chassis, where every change at the contact patch is felt straight through the wheel.

About the Hollow rear brake kit

This is a rear-axle big brake kit built around two-piece floating discs with a hollow-vane core, where material is machined out of the rotor to cut rotating and unsprung mass while keeping the swept area that does the cooling and the stopping. Lighter rotating mass at the rear of a mid-engined car matters: it eases the work the dampers and the light 4C structure have to manage over kerbs and quick direction changes.

Disc face is drilled or slotted at the same price, and centre bell upgrades, two-tone anodizing in five colours or titanium, are selectable when you order. Three pad compounds – Street, Sport and Racing – let you match the friction material to how the car is actually used, from road miles to dedicated track sessions. The caliper is hollow-body as standard, finished in the included painted colours Red, Yellow, Gold, Black or Anodized Black at no extra cost, with any Pantone available as a Custom Color and a premium tier of polished-forged Titanium, Polished Gold and Polished Silver plus candy Teal, Blue, Red and Orange. The Hollow Racing caliper, with no dust cover, a 1000C rating and a two-year warranty, suits serious track use.

Fitment for the Alfa Romeo 4C (2013-2018)

This is the rear-axle application for the Alfa Romeo 4C across the full 2013 to 2018 production run, covering both the coupe and the later Spider. It is a rear-only kit, so decide whether you are also upgrading the front axle to keep your brake balance where you want it.

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 330–356mm (rear). 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.
