XYZ Racing Street Advanced Coilovers — Mazda MILLENIA 1993-2003

The Mazda Millenia sits in an awkward corner of the catalogue – a front-drive executive saloon with the optional Miller-cycle KJ-ZEM V6, soft factory damping, and a kerb weight that pushes 1,500kg before you put fuel in it. Owners running an MA21 in 2026 are doing so by choice, and the choice usually comes with a clear brief: keep the long-distance ride that made the car desirable in period, but stop the body roll and front-end float that the original struts give up after thirty years.

The XYZ Racing Street Advanced coilover is built for exactly that brief. It is the road-biased kit in the XYZ range – a height-adjustable, damper-adjustable replacement for the worn-out OE struts, set up to firm the Millenia without turning it into something you stop wanting to drive to work.

What this coilover does for your 1993-2003 Mazda MILLENIA

Drop a Street Advanced kit onto an MA21 and the first thing you feel is the nose stops diving on trailing-throttle entries – useful on a car this long and this softly sprung from the factory. Ride height comes down to a sensible road drop, which tightens the visual stance without burying the front splitter on speed bumps. The 30-way damping range gives you a quiet, compliant motorway setting and a firmer weekend setting, and the adjustment is at the top of the strut so you are not pulling wheels off to make a change. Springs and dampers are matched as a system, so the front and rear axles work in phase under load rather than the rear running out of travel first – the failure mode every tired Millenia exhibits.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s road-and-occasional-track tier. Construction is monotube with a steel body, with the damper valving tuned softer than the Super Sport and Circuit Master kits further up the range. Spring rates are picked to keep the car driveable on UK B-roads rather than chasing lap times – a deliberate choice for a chassis that was never sold as a sports saloon. Ride height is adjustable independently of spring preload, which matters: you can corner-balance the car and still set the drop you actually want, instead of compromising one for the other. The kit is rebuildable and revalvable at XYZ’s facility, so a Millenia owner planning to keep the car another decade isn’t buying a disposable item.

Fitment for the Mazda MILLENIA (1993-2003)
