Taking a 1997-2002 Diamante to a circuit is a deliberate choice. Mitsubishi designed this executive saloon for motorway comfort – soft damping, generous suspension travel, and spring rates calibrated for ride compliance over cornering precision. The V6 sits well ahead of the front axle, and on track that nose weight manifests as progressive understeer that builds as the factory suspension runs out of control under sustained lateral load.
The XYZ Racing Racing Spec coilover is built for exactly this kind of application: where the gap between factory luxury calibration and circuit use is wide, and where the driver needs a suspension system developed from actual competition data rather than adapted from a road-biased range.
What this coilover does for your 1997-2002 Mitsubishi Diamante
Lowering the Diamante reduces the car’s centre of gravity and removes the factory body roll that bleeds cornering speed before the chassis has reached its limit. With the Racing Spec calibration, damping rates are set for the demands of circuit use rather than kerb absorption, giving the front axle a consistent response through fast direction changes where the standard setup pitches and recovers unpredictably. Reduced dive under hard braking means front geometry stays where it was set rather than compressing into increasingly aggressive understeer at corner entry. Ride height adjustability lets owners optimise stance for their chosen circuit layout rather than living with the comfort-biased sag of the factory setup.
About the Racing Spec coilover
The Racing Spec damper is developed specifically for track racing, with calibration settings derived from XYZ Racing’s direct involvement in circuit competition including events at WTCC level. These are not road coilovers repositioned for occasional circuit use – the settings originate from the paddock. For Diamante builds that go significantly beyond a standard circuit configuration – cars running aggressive drivetrain or chassis upgrades comparable to factory race vehicles or A-class competition machines – a bespoke shock absorber can be manufactured to order. Owners supply details of their upgraded components and target circuit, and XYZ develops a custom specification around those parameters. The Racing Spec range sits at the serious end of what a road-registered car typically runs; the custom route takes it further for those whose car demands it.
Fitment for the Mitsubishi DIAMANTE (1997-2002)
This coilover kit is built to chassis code MT11-1 and covers the Mitsubishi Diamante across the 1997-2002 production years. Confirm your vehicle’s year of manufacture against this range before specifying. No trim-level or subvariant exclusions apply to this fitment – the MT11-1 designation within those years is the qualifying criteria.

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.
