XYZ Racing Street Advanced Coilovers — Mitsubishi STARION welding 1982-1990

The Starion’s MT34 chassis puts a turbocharged inline-four ahead of a live rear axle, a layout that rewards a coilover set-up which can settle body movement without turning the ride harsh on a cold, damp B-road. XYZ Racing’s Street Advanced kit is built for exactly that brief: fast road use with the option of the odd track day, not a car that lives on slicks.

On a nearly 40-year-old platform like this, bushings, mounts and factory dampers have usually given up long before the springs have. Dropping in a coilover set-up here isn’t about shaving lap times, it’s about giving the Starion’s chassis a fighting chance to behave the way it did when new, with the adjustment range to tune it as your own car and roads dictate.

What this coilover does for your 1982-1990 Mitsubishi STARION WELDING

Fitting this Street Advanced coilover kit to a 1982-1990 Mitsubishi Starion restores control that decades of worn OE dampers can’t match, tightening body roll through direction changes and reducing the float that turns this era of live-axle rear end unsettled over mid-corner bumps. The 720-way damping adjustment means you can run the front end firm enough to check dive under braking while keeping the rear compliant enough to put power down out of slower corners, rather than locking the whole car into one compromise setting. Ride height is adjustable independently of spring preload, so you can correct the Starion’s stance without changing the effective spring rate you’ve chosen. For a car this age, that adjustability also means you can wind the set-up back toward comfort for a motorway run and firm it up again for a spirited drive, without swapping parts.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s core road-and-track product, developed over a number of years by the brand’s in-house engineering team and refined through use in races run worldwide. That competition use fed back into the road-going version sitting here: a kit designed to work equally well as a daily set-up or a track-day tool, rather than being tuned exclusively for one or the other. Its headline spec is 720-way damping adjustment, giving a genuinely wide window between comfort and control instead of a handful of coarse steps. The construction is built to take that adjustment range without the dampers losing consistency as they’re wound between settings. For drivers who want to push a car’s cornering speed and still trust the chassis underneath them, this is the type built to deliver both sides of that equation on one set of dampers.
