The W454 was the odd Smart out: front-engined, front-wheel drive, and built on Mitsubishi Colt underpinnings rather than the rear-engined layout of its ForTwo sibling. That gives it a tall body over a short wheelbase, and the factory set-up leans on soft damping to keep things comfortable – which costs you composure the moment you load the front axle.
The XYZ Racing Super Sport coilover is the fast-road answer to that. It pairs full height adjustment with 36-way damping, so you can drop the Forfour’s stance, tighten the body control, and still keep a ride that copes with a broken B-road or a weekend track session.
What this coilover does for your 2004-2007 Smart Forfour
Lower the ride height and the Forfour’s centre of gravity comes down with it, taking the worst of that top-heavy lean out of quick direction changes. The 36-way damping is the part you will feel most: wind it soft for commuting on poor surfaces, then firm it up for a circuit day without touching a spring perch. Front-end bite improves under trail-braking, and the nose stops diving every time you lift off the throttle. On a car this light and this short in the wheelbase, even small changes in damping force translate into a noticeably tied-down feel through roundabouts and tighter corners.
About the Super Sport coilover
The Super Sport sits in XYZ Racing’s range as the do-everything damper, built to take the harshness out of bumps and rough surfaces rather than punish you for the privilege of lowering the car. Ride height is fully adjustable on the threaded body, so you set the stance and corner balance to suit the Forfour rather than accepting one fixed drop. The headline figure is 36 steps of damping adjustment, a single setting that governs how the kit reacts over compression and rebound, letting one car cover daily driving and weekend track running. XYZ pitches it as a high-performance damper that copes with all road conditions, and that breadth is the point: it is meant for the owner who uses the car through the week and still wants it to behave when the pace picks up.
Fitment for the Smart Forfour (2004-2007)
This kit is matched to the W454 Smart Forfour built from 2004 to 2007 – the first-generation, Mitsubishi-derived four-seat car rather than the later W453 model. Confirm your chassis code reads W454 before ordering, since the platform change between Forfour generations means a later car takes different hardware.
