XYZ Racing Racing Spec Coilovers — Smart FORFOUR (W454) 2004-2007

Forget the rear-engined Fortwo: the W454 Forfour is the odd one out in the Smart range, a front-engined, front-wheel-drive supermini built on Mitsubishi Colt underpinnings at the NedCar plant in the Netherlands. That nose-led layout, tall body and stubby wheelbase give the Forfour a darty, slightly tail-light feel on turn-in and a tendency to lean and pitch when you start leaning on it. Those are exactly the traits a serious track setup exists to bring to heel.

The XYZ Racing Racing Spec coilover is the sharpest end of the range for this car, built for circuit and time-attack use rather than fast-road comfort. On a light, short-wheelbase chassis like the W454 – especially the Brabus turbo cars putting heat through the front axle – the gains from proper damping control are felt almost immediately.

What these coilovers do for your 2004-2007 Smart Forfour (W454)

Drop the ride height and you pull the Forfour’s relatively high centre of gravity down, which cuts the body roll that blunts this car’s responses through quick direction changes. Height-adjustable spring platforms let you corner-balance the chassis and set the stance you want without losing usable travel. Firmer, motorsport-oriented damping keeps the short wheelbase from pitching under braking and squatting under power, so a front-drive Forfour stays settled and keeps its front tyres loaded mid-corner. The net result on track is a car that turns in cleaner, holds a line you can trust, and stops reacting nervously over kerbs and mid-corner bumps.

About the Racing Spec coilover

Racing Spec is XYZ Racing’s circuit-focused damper, and the spec is not theoretical. The valving and settings were developed through direct competition, including the WTCC touring car series, so the baseline tune reflects what works on a stopwatch rather than a brochure. For cars running aggressive modifications – the kind of setups closer to a works racing car or an A-class race build – XYZ Racing will produce bespoke shock absorbers built around your specific package. You supply the detail on your upgrades and the circuit you intend to run, and the dampers can be valved to suit that combination rather than a generic average. It is the closest a catalogue coilover gets to a custom-order race part.

Fitment for the Smart Forfour (W454) (2004-2007)

This kit is built specifically for the W454 Smart Forfour produced from 2004 to 2007, the front-wheel-drive Colt-based generation. It suits the full first-generation Forfour run, Brabus turbo cars included. Confirm your chassis code reads W454 before ordering, as it does not share fitment with the rear-engined Fortwo.
