Smart FORFOUR (W454) 2004-2007 — Coilovers

The first-generation Smart Forfour carries its mass high over a stubby wheelbase, and that geometry is the first thing you feel when you lean on it. Built on Mitsubishi’s Colt platform and assembled at NedCar in Born, the W454 was never set up to resist roll – the soft factory springs let the body lean early and overload the outside front tyre long before the chassis is doing any real work. XYZ Racing coilovers for the Smart Forfour (W454) 2004-2007 go straight at that weakness.

Swapping the standard struts for a height- and damper-adjustable setup drops the centre of gravity, tightens the body control, and gives this front-drive supermini the composure its short wheelbase always wanted. From the modest 1.1 and 1.3 petrols to the Brabus-tuned 1.5 turbo, the gain in turn-in bite and mid-corner stability is immediate.

What these coilovers do for your 2004-2007 Smart Forfour

On the road, the clearest change is stance and body control: set the W454 to a sensible lowered ride height and it stops heaving over crests and diving under braking. Damping adjustment lets you firm things up for a B-road run or back them off for the daily commute, so the car stays usable as everyday transport. Less roll means the front tyres load more evenly, which sharpens the steering this Colt-derived chassis tends to numb. On track or at an autosolo, the lowered roll centre keeps the inside rear planted through tight direction changes – the low-speed agility a short-wheelbase Forfour can genuinely exploit. Set the ride height and camber properly and tyre wear evens out as well.

About the XYZ Racing coilover range for the W454

XYZ Racing offers the W454 coilover in six specifications, each a height-adjustable damper-and-spring unit that replaces the soft factory struts. The range runs from Super Sport and Top Sport, aimed at fast-road driving with occasional track days, through Racing Spec and Circuit Master for committed circuit use, to the discipline-specific Tarmac Rally and Drift Spec. Adjustable ride height is standard across the range, set on the threaded strut body so the Forfour keeps proper damper travel even when slammed. The sportier specifications add separately adjustable damping, letting you tune how the car reacts to mid-corner bumps versus weight transfer. Spring rates rise with the specification, chosen to suit the W454’s light kerb weight rather than simply being made as stiff as possible. Each kit works with the standard strut mounting points, so the geometry the factory built in is preserved.

Fitment for the Smart Forfour (2004-2007)

These coilovers are cut for the W454 Forfour built from 2004 to 2007 – the first-generation, Mitsubishi Colt-based car assembled at NedCar, not the later Renault-Twingo-based W453. Confirm your car falls inside that 2004-2007 production window before ordering, then choose the specification that matches how you actually use it.
