The Mitsubishi Diamante’s long-wheelbase, front-heavy platform was calibrated at the factory for quiet motorway miles rather than committed driving. On a real road, the result is pronounced body roll and vague steering feedback through the front axle – not because the Diamante is a bad car, but because Mitsubishi optimised it for very different priorities than most current owners actually want.
The Super Sport coilover addresses exactly that. XYZ Racing’s mid-range street-and-track kit brings 36-way damping adjustment and full ride-height control to the MT11-1 chassis, allowing owners to reset the suspension balance toward something the original engineers left firmly on the table.
What this coilover does for your 1997-2002 Mitsubishi DIAMANTE
The immediate effect on the Diamante is a sharper handling balance: body roll pulls in, steering response quickens, and the tendency for the front end to push wide under load becomes manageable rather than a constant negotiation. Ride height adjustment lets owners drop the centre of gravity without sacrificing ground clearance on a car that covers real road mileage between circuit appearances. The 36-way damping range delivers genuine separation between a comfortable daily setting and a firmer weekend calibration – a spread that matters on a heavy FWD saloon where carrying a full load or driving at pace changes the dynamics considerably.
About the Super Sport coilover
The Super Sport sits in the mid-tier of the XYZ Racing coilover range, positioned for the driver who wants road composure alongside the option of circuit use without running separate setups. The kit was developed specifically to absorb the discomfort of rough and irregular roads – a practically relevant design brief on a platform the size and weight of the Diamante, where Mitsubishi’s original calibration erred heavily toward softness. Ride height is fully adjustable, and the 36-way damping system allows the driver to set the car for any condition from a single pair of adjusters. XYZ Racing rate the Super Sport for both weekend circuit use and regular daily driving, which reflects how most Diamante owners actually use these cars in 2026.
