XYZ Racing Circuit Master Coilovers — Mitsubishi ECLIPSE 1989-1995

The first-generation Eclipse MT12 arrived through Mitsubishi’s Diamond Star Motors venture, sharing a platform with the Eagle Talon and Plymouth Laser but carrying its own character – particularly in AWD GSX form, where the 4G63T’s torque met genuine all-wheel-drive traction. Thirty-plus years on, the owners keeping these cars on circuit are working with suspension geometry calibrated for a different era of tyre compounds and lap times.

XYZ Racing’s Circuit Master coilover for the 1989-1995 Eclipse is built around one premise: sustained circuit performance. With 9720 adjustment combinations available across three separate knobs, it gives the DSM owner the resolution to tune around the platform’s specific handling traits – nose-heavy weight distribution, torque steer on front-wheel-drive variants, and the traction balance differences between the FWD and AWD drivetrains.

What this coilover does for your 1989-1995 Mitsubishi Eclipse

Fitted to the Eclipse MT12, the Circuit Master transforms the contact patch conversation. Where factory suspension was calibrated for a broad population of drivers on standard road tyres, the three-knob system provides independent control over spring rate, rebound, and compression – enough resolution to distinguish between different circuit surfaces, tyre compounds, and driving styles. The small oil hole design governs oil flow under high-load inputs at speed; this produces minor noise over sharp-edged road bumps, which is an expected characteristic on a circuit-specification damper and a non-issue on smooth track tarmac. Height adjustment brings the MT12’s stance low enough to shift the centre of gravity meaningfully, sharpening turn-in across the front axle.

About the Circuit Master

Sitting alongside the Racing Spec, Drift Spec, and Tarmac Rally variants at the top of XYZ Racing’s competition line, the Circuit Master has been validated by XYZ Racing teams on tracks worldwide. Its 9720 adjustment combinations come from three dedicated knobs – a figure that reflects the resolution required when the difference between a personal best and a podium comes down to specific damper tuning at a specific circuit. The small oil hole construction is a deliberate design choice: the restricted passage controls oil movement through large-input events, a characteristic of no consequence on the smooth tarmac the damper was designed for. Everything about this build is oriented toward sustained circuit lap performance, not daily road comfort.

Fitment for the Mitsubishi Eclipse (1989-1995)

The XYZ Racing Circuit Master coilover fits the Mitsubishi Eclipse with chassis code MT12, covering the full first-generation model run from 1989 to 1995. This span includes both the front-wheel-drive and all-wheel-drive variants produced under the Diamond Star Motors joint venture.
