XYZ Racing Super Sport Coilovers — Infiniti Q45 (Y32) welding 1991-1996

The Y32-generation Q45’s factory suspension was tuned in the early 1990s for a soft, wafting ride rather than body control, and on a car this size – a full-size, rear-wheel-drive V8 saloon – that softness shows up first as dive under braking and roll through faster corners. The XYZ Racing Super Sport coilover kit, built for this welded-mount Q45 fitment, replaces that factory geometry with a set-up that puts ride height and damping under the owner’s control instead of leaving them fixed to whatever Nissan specified in 1991.

This is the fast-road and weekend-track spec in the XYZ Racing range: firm enough to keep a heavy saloon settled under load, still liveable enough for the drive home afterwards. For a Y32 that spends more time on spirited road drives than on a race grid, that balance is the one that actually matters.

What this coilover does for your 1991-1996 Infiniti Q45 (Y32)

Ride height adjustment lets you drop the Q45’s tall factory stance and bring the wheels closer to the arches without sacrificing the suspension travel a car this size still needs on UK B-roads. The 36-way damping adjustment lets you set compression and rebound independently of spring rate, so you can firm the car up for a track day and back it off again for the motorway run home. Because the kit corrects the vague, over-soft character of the standard suspension, turn-in feels more direct and the nose stays settled under trail braking instead of diving into the corner. Ride quality on rough tarmac, the exact discomfort XYZ Racing designed the Super Sport damper to remove, improves rather than worsens, because the damping is tuned to the car’s actual weight rather than a thirty-year-old factory valve.

About the Super Sport coilover

XYZ Racing built the Super Sport damper to solve a specific complaint: factory and budget coilover set-ups that transmit every bump and expansion joint straight into the cabin. The damper body adjusts ride height independently of the spring perch, so preload and stance can be set without changing spring rate. Damping runs across 36 discrete settings, giving enough range to move between a comfortable daily set-up and a firmer track-day tune without swapping parts. That range is the point of the Super Sport line – positioned between XYZ Racing’s full competition dampers and its street-only options, built to cover weekend racing and everyday driving from a single kit rather than forcing a choice between the two.

Fitment for the Infiniti Q45 (Y32) (1991-1996)

This kit is specced for the Y32-chassis Q45 built between 1991 and 1996, in a welded-mount configuration rather than a bolt-in top mount. Confirm your car carries the Y32 chassis code before ordering, since Infiniti reused the Q45 name across later generations with different suspension architecture.
