The 1997-2002 Diamante carries its executive brief into every suspension setting: soft springs, damping calibrated for four-occupant comfort rather than lateral load management, and a weight distribution dominated by the 3.0-litre V6 sitting well ahead of the front axle. On a circuit, that combination produces excessive body roll into corners followed by chronic understeer as the front tyres work to manage more load than the factory calibration was ever intended to handle.
For Diamante owners chasing lap times, the XYZ Racing Circuit Master coilover kit resets the suspension from the ground up. Built not for occasional spirited road use but for the specific demands of sustained circuit lap-time work, it is the specification that takes this saloon’s unlikely circuit potential seriously.
What this coilover does for your 1997-2002 Mitsubishi DIAMANTE
Replacing the factory suspension on the Diamante’s front axle introduces front-end control the standard components cannot deliver. Body roll drops sharply, allowing the front tyres to work consistently rather than loading unevenly mid-corner – critical on a front-heavy FWD saloon where the axle response dictates the entire handling balance. Three independent adjustment knobs govern damping response and ride height separately, giving you the granularity to tune around the Diamante’s particular weight distribution rather than accept a fixed compromise. The 9,720 available adjustment combinations provide the range to set the chassis for different circuit surfaces and grip levels across a full season rather than locking it to a single static setting.
About the Circuit Master
Sitting at the top of XYZ Racing’s competition range, the Circuit Master shares its development lineage with the Racing Spec, Drift Spec, and Tarmac Rally derivatives – all validated by XYZ’s own racing teams at international circuits through an extended real-conditions testing programme. The headline specification is 9,720 distinct damping settings, reached through three knobs governing independent aspects of the damper response. Construction uses a small oil hole design; when the coilover absorbs a large chassis input, oil passes through this restricted passage and may produce a minor sound at that moment – this is characteristic of the design, not a fault. Because the Circuit Master is calibrated exclusively for circuit tracks, the calibration logic does not carry the ride-compliance compromises found in road-oriented setups; on a smooth racing surface, that focus is an advantage.
Fitment for the Mitsubishi DIAMANTE (1997-2002)
This kit covers the Mitsubishi Diamante across the full 1997 to 2002 model year span, XYZ chassis reference MT11-1. Verify your car’s trim and any factory suspension specification against that code before ordering, particularly if your Diamante carries optional factory suspension upgrades from that production run.

The configurator below carries everything you need to confirm your 1997-2002 Diamante fitment year and build yours.
Because its 3 adjustment knobs with small oil hole design, when driving through big bumps, the coilover oil will go through small passage which might cause some small noise. This is normal situation. This product is made for circuit tracks and there will be no concern for bumps on the tracks.
Top mounts included with your kit
Every XYZ Racing coilover kit ships with the upper mounts listed below for your exact chassis — no extra parts to source.
Pillow ball + rubberP+Pillow-ball upper with a rubber insert — adds steering precision and camber adjustability while keeping some of the factory mount’s harshness damping.
Hardened rubberRHardened rubber upper — firmer than the factory bush for tighter response while retaining road-friendly noise and vibration isolation.
AluminiumAAluminium upper mount — a stiff, lightweight housing that locates the damper precisely and resists flex under load.
