The Bertone X1/9 is a mid-engined oddity that rewards anyone willing to put proper suspension under it. Its short wheelbase, transverse 1.5-litre layout and near-50/50 weight distribution mean the chassis has always wanted more damping authority than the soft factory struts were ever asked to provide. The XYZ Racing Super Sport coilover for the Fiat Bertone X1/9 1982-1989 gives the car the height control and damper range it needed forty years ago.
This is the spec to fit if you are running an X1/9 on the road most weekends, with the occasional trackday or hillclimb in the diary. It tightens body movement without turning a 900kg targa-topped Italian into something brittle on a B-road.
What this coilover does for your 1982-1989 Fiat Bertone X1/9
Ride height comes down to whatever the arches and Bertone’s tight wheel wells will tolerate, which finally lets the X1/9 sit with the stance it always deserved. The 36-way damping adjustment is the meaningful bit on a car this light – small clicks make a visible difference when you have under a tonne to control. Turn-in sharpens because the front end stops pattering over mid-corner ridges, and the mid-engined rear stops squatting under power out of slow bends. On a rough fast road the Super Sport platform takes the edge off the broken surfaces that the original struts simply crashed through. Brake confidence improves too – less nose-dive under load means the front discs are working at a consistent ride height rather than at the bottom of their travel.
About the Super Sport coilover
The Super Sport is XYZ Racing’s fast-road platform with track-day capability built in. It runs full ride-height adjustment independent of damper preload, and the 36 detents of damping let you bracket between a compliant road setting and a firmer trackday setting from the driver’s seat. The vendor’s own brief is blunt about it: the damper is engineered to eliminate the discomfort of bumps and rough roads while still being set up for weekend race use. Construction is high-performance for a coilover at this price point – the same family of internals XYZ runs across its road-and-track range, sized down to suit the X1/9’s modest unsprung weight. It is the right pick when you want one suspension setup that handles a Sunday drive over Welsh tarmac and a Castle Combe trackday in the same weekend.
