XYZ Racing Top Sport Coilovers — Mitsubishi ECLIPSE TURBO 4WD 1989-1995

The Eclipse Turbo 4WD’s viscous-coupling AWD system routes torque to the front axle the moment the rear wheels start to slip, and on the factory dampers that transfer shows up as a wallowy front end under power and a nose that dives hard the instant you lift. XYZ Racing’s Top Sport coilover kit for the Mitsubishi Eclipse Turbo 4WD (MT13, 1989-1995) is built around a firmer spring and damping baseline specifically to control that front-axle weight transfer.

Top Sport sits between XYZ’s fast-road and full-race lines: stiff enough for an occasional track day, still compliant enough to drive the 4G63T-powered Eclipse to work on a Monday. It’s the spec for owners who want one set of coilovers to cover both.

What this coilover does for your 1989-1995 Mitsubishi Eclipse Turbo 4WD

Fitted to the MT13 chassis, the Top Sport kit raises spring rate roughly 2kg/mm over the factory setting and steps damping force up 30-50%, which matters most on this car because the AWD hardware and 4G63T turbo motor sit further forward than a front-drive Eclipse. That extra front-end control keeps the nose settled through trail-braking into a corner, rather than diving and loading the outside front tyre unevenly. Through the exit, where the viscous coupling is shuffling torque rearward, the stiffer rear rate keeps the back axle planted instead of squatting and washing out the AWD’s traction advantage. Ride height is also adjustable independently of spring preload, so you can correct the nose-down stance the extra front-end weight tends to create on the standard setup, and settle the car back onto a level stance for consistent geometry front to rear.

About the Top Sport coilover

XYZ’s Top Sport line runs a spring rate roughly 2kg/mm firmer, and damping increased 30-50%, over what the equivalent street-spec kit ships with. The extra resistance is there to absorb the jolt of a sharp compression – a kerb strike, a mid-corner ridge, a botched apex – without the body of the shock kicking back into the chassis, which is what causes a car to skip sideways over broken surfaces. Controlling that body movement keeps the tyre’s contact patch loaded evenly, which is where the traction actually comes from mid-corner. The valving in this range was set using XYZ’s own track-day and race programme, tuned to hold the car flat and predictable rather than to chase outright lap time. That’s what makes Top Sport the spec for aggressive driving and the odd track day, rather than a car that lives permanently on a trailer.

Fitment for the Mitsubishi Eclipse Turbo 4WD (1989-1995)

This kit is built to the MT13 chassis code, covering the Mitsubishi Eclipse Turbo 4WD across its full 1989 to 1995 production run. It’s specific to the AWD, turbocharged variant of the first-generation Eclipse – confirm your car carries the viscous-coupling 4WD drivetrain and turbo 4G63 engine before ordering, as the front-drive and naturally aspirated versions of this generation use a different spec.
