XYZ Racing Super Sport Coilovers — Daihatsu SIRION Rear: Non-ride height adjustable 1998-2005

The first-generation Daihatsu Sirion is a featherweight on stilts from the factory – tall springs, soft dampers, and a ride height tuned for Japanese B-road compliance rather than UK corner-entry confidence. Drop the unsprung mass into a properly damped coilover and the M100’s natural agility wakes up; the short wheelbase stops feeling nervous and starts feeling pointable.

The XYZ Racing Super Sport for the DI04 Sirion is built around that reality. It is the fast-road-leaning kit in the XYZ range, with the damper authority to handle a weekend track day without turning the daily commute into a chore.

What this coilover does for your 1998-2005 Daihatsu Sirion

Switching to the Super Sport gives the Sirion a flatter mid-corner attitude and tighter body control over crested A-roads, where the standard car’s tall stance lets it heave between transitions. The 36-way damping adjustment is the headline benefit on a car this light – small clicks make a felt difference, because there is not much mass for the damper to fight. You get sharper turn-in, less roll on motorway slip roads, and a brake-zone platform that settles quickly enough to load the fronts cleanly. The construction copes with British road surface mid-week and a Cadwell trackday at the weekend without needing two sets of settings.

About the Super Sport coilover

The Super Sport is XYZ Racing’s dual-purpose damper aimed at owners who want a single setup for road and occasional track use rather than a dedicated competition kit. Damping is adjustable across 36 detented positions on a single knob per corner, letting you bias the car softer for broken surfaces or stiffer for sustained cornering loads. Ride-height adjustment is built into the kit so corner weights and rake can be set up properly rather than left to spring perch position alone. XYZ engineered the valving to absorb sharp bump inputs – potholes, expansion joints, rough back roads – without losing the high-frequency control needed when the surface smooths out on a circuit. The result is a kit that does not punish you for daily-driving it.

Fitment for the Daihatsu Sirion (1998-2005)

This kit fits the DI04 chassis Sirion produced from 1998 to 2005, in the Rr non-ride-height-adjustable application as listed. Confirm your model year and trim before ordering; the early Sirion shared platform underpinnings across markets, so the chassis code is the safer reference than the badge year.
