Caliper render for this kit:
The W453 ForTwo’s rear-engine layout puts more static mass over the back axle than almost anything else in its class, which is exactly why the factory front brakes are specified conservatively. Under gentle driving the load distribution never demands anything heavier. Push the car through a sprint event or an auto-gymkhana loop, though, and the picture flips: under hard repeated stops weight transfers forward aggressively, the small OEM discs swallow that energy, and thermal fade arrives well inside a single session. The XYZ Racing Hollow Front Brake Kit is built to solve that specific problem.
At under 900kg the ForTwo needs less absolute braking force than a full-size hatch, but the stock front hardware reaches its thermal ceiling far sooner than the chassis ever does. This is a front-axle kit: a matched pair of front calipers and two-piece floating discs for the left and right corners, sized to give the W453 the fade resistance it needs while keeping rotating mass low enough to protect the car’s lively turn-in.
What this brake kit does for your 2014-2026 Smart SMART (FOR TWO)
The two-piece floating discs run an aluminium centre bell bolted to an iron friction ring, so the disc stays true through repeated heat cycles and carries less rotating mass at the wheel. The disc itself is hollow-vaned, drawing cooling air through internal channels rather than letting heat soak into solid metal, which keeps temperatures out of the fade window during the short, repeated braking intervals an auto-gymkhana or sprint layout serves up twenty times a session. Less rotating and unsprung weight also means the front end picks up and releases the brakes faster, and the suspension settles more cleanly over surface changes.
Three pad compounds let you match the friction to how you actually drive the car. Street is the quiet, low-dust road default; Sport adds bite and heat range for fast road with the occasional track day; Racing is a full circuit compound for drivers chasing consistency across a longer run. Braided stainless lines are included for a firmer, more repeatable pedal than rubber hoses that swell under pressure.
About the Hollow Front Brake Kit
The hollow-vane name describes the disc’s internal ventilation. Cooling passages run through the rotor body and pull air across the friction surfaces while the wheel turns, so heat sheds into the airstream continuously instead of building with nowhere to go. The calipers are hollow-body as standard, stiff without carrying excess weight, and the kit covers the front axle as a pair because that is where most of the braking load lands under hard deceleration, even on a tail-heavy car like the ForTwo.
Discs come drilled or slotted at the same price, so you can choose on looks or wet-weather feel. Included caliper finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color to any Pantone code for a small upcharge. Premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) sit in a separate upgrade tier. Two-tone centre bells in five anodized colours, or a titanium bell, are selectable at checkout. For serious track use there is an optional Hollow Racing caliper, run without a dust cover, rated to 1000C and backed by a two-year warranty. On a car as visually distinctive as the ForTwo, with short overhangs and open-spoke wheels common in the scene, caliper finish is not an afterthought.
Fitment for the Smart SMART (FOR TWO) W453 (2014-2026)
This kit is specified for the third-generation Smart ForTwo, chassis code W453, covering production from 2014 through to 2026. That takes in both the 71bhp and 90bhp turbocharged three-cylinder variants across the generation’s run, and fits the front axle as a left-and-right pair. Confirm the W453 chassis code against your vehicle documents 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.
