XYZ Racing Top Sport Coilovers — Mitsubishi STARION welding 1982-1990

The Starion’s long-nose, rear-wheel-drive turbo layout was built for a different era of tyre and suspension technology, and thirty-plus years on, the factory struts are the weak link in an otherwise characterful chassis. The XYZ Racing Top Sport coilover replaces that ageing set-up on the MT34 with a spec built for cars that see the odd track day between road use – enough control to keep the car settled under power without turning every commute into a compromise.

For a Starion built between 1982 and 1990, that matters because so much of what’s left on UK roads has already had at least one round of suspension bodges. Top Sport gives the platform a proper baseline again, tuned for drivers pushing the turbo motor hard rather than just cruising.

What this coilover does for your 1982-1990 Mitsubishi Starion Welding

Damping is increased 30-50% over a standard street set-up (or the spring rate is lifted around 2kg/mm, depending on the configuration chosen), which is the difference that actually shows up on a B-road with mid-corner bumps – the Starion’s rear axle stays loaded instead of skipping. Hitting a pothole or a sharp ridge at speed no longer sends a jolt straight through the shell; the shock body absorbs it and the chassis stays composed rather than getting deflected off line. That control keeps more of the tyre’s contact patch working under load, which on a rear-drive turbo car translates directly into more usable traction out of a corner. The net effect on the Starion is a car that turns in with less float and puts power down with less drama, which is exactly what a chassis this old needs before you trust it on a circuit.

About the Top Sport coilover

Top Sport is XYZ Racing’s track day tune, and it’s built around the same damping and spring philosophy the brand runs in its own racing programme rather than a softened-off retail compromise. Damping is stepped up 30-50% and spring rates roughly 2kg/mm over a street baseline, specifically so the kit can shrug off the impact of rough pavement and bigger hits without the body pitching or the dampers overwhelming. That extra control is what keeps the tyre planted through a fast direction change, which is where the "vehicle stability" XYZ Racing talks about actually comes from – a car that holds its line instead of wallowing. It’s the spec to pick if the Starion sees a handful of track or sprint days a year alongside road use, rather than one built purely for daily comfort.

Fitment for the Mitsubishi Starion Welding (1982-1990)

This kit is specified for the Mitsubishi Starion, chassis code MT34, across the full 1982-1990 production run, in the Welding mounting configuration. Confirm your car matches the MT34 code and welding-type top mount before ordering, since Starion suspension hardware varied across the model’s UK and grey-import history.
