XYZ Racing Street Advanced Coilovers — Mitsubishi DIAMANTE 1997-2002

The MT11-1 Diamante sits in an unusual position among late-1990s Japanese cars: a large, V6-powered executive saloon built squarely around Mitsubishi’s comfort brief, not a performance agenda. The factory suspension reflects that – conservative spring rates, long travel, and damping tuned to smooth out road imperfections rather than communicate them. For owners who want a more connected handling balance without abandoning the car’s essential character, the Street Advanced coilover kit provides a complete hardware solution.

This is the Street Advanced series – XYZ Racing’s most widely fitted coilover range, developed for road use and track day crossover. The 720-way damping adjustment positions sit at the core of the spec: a wide enough spread to cover the difference between a relaxed urban tune and a genuinely committed circuit set-up.

What this coilover does for your 1997-2002 Mitsubishi Diamante

The Diamante’s factory body roll is the first thing that changes. Replacing the OEM struts and rear units with the Street Advanced drops the centre of gravity and installs spring rates calibrated to the MT11-1’s weight and geometry, making the car far more responsive under direction changes than the standard setup allows. The 720-position damping adjustment means the same kit covers a motorway run and a track session – stiffen the compression for the circuit, ease off for the commute. Adjustable ride height provides further scope to optimise the car’s stance and handling balance.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s core coilover line – developed over years by the XYZ professional engineering team and refined through testing at major racing events worldwide before the production specification was confirmed. The range is built for the dual brief of road comfort and circuit capability: robust enough to absorb repeated track day use, compliant enough to remain a practical daily driver. 720 distinct damping adjustment positions give the Street Advanced a tuning range that genuinely means something – from the softer end of the spectrum for comfort-oriented road use through to a considerably more connected set-up for faster driving.
