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

The Y32 Q45’s strut towers were never drilled for an aftermarket adjustable perch, which is why this kit is a welding-type fitment rather than a bolt-in swap: the top mount gets fabricated onto the chassis rather than clamped to an existing hole pattern. It’s a fair reflection of what this car is – Infiniti’s V8 flagship saloon, repurposed by owners who want it to actually turn in and stop rather than just cruise.

XYZ Racing’s Racing Spec coilover is the range built for that repurposing: serious track and time-attack use, not a comfort-first fast-road setup. On a car carrying real weight over the front axle, that means damping and spring rates chosen to keep the nose settled under braking and the rear axle controlled through direction changes, rather than softened off for a smooth commute.

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

Fitted to a 1991-1996 Q45, this coilover kit gives you a fixed point to work from every session: independent ride height adjustment lets you set the front low enough to load the tyres properly without running out of suspension travel over kerbs, and the damper settings hold that geometry steady instead of letting the nose dive and wallow under braking. Because the top mount is welded rather than bolted, the whole assembly sits rigidly in the chassis – no compliance in the mounting itself to eat into the damping you’ve paid for. Spring rates matched to a heavier rear-wheel-drive saloon mean body roll through direction changes is controlled rather than masked, which matters more on a car this size than on a lightweight hot hatch. On track or a fast road session, the result is a Q45 that changes direction and slows down in a way its V8 chassis was never originally set up to do.

About the Racing Spec coilover

Racing Spec is XYZ Racing’s dedicated circuit-racing damper, and the tuning behind it comes from actual competition rather than a bench test: the damping curves were developed through direct involvement in touring car racing, including WTCC-level events, and carried across into the road-going range. For cars running genuinely aggressive modifications – full aero, weight reduction, forced-induction upgrades – XYZ Racing also offers a bespoke build path. Send over the detail of what’s been changed on the car and which circuit it’ll be run on, and the factory will produce a custom-valved shock absorber around that specific setup rather than a generic off-the-shelf unit. For the Y32 Q45, that matters because the welded fitment already puts this car outside the standard bolt-in catalogue – buyers building toward serious time-attack pace have the option to go further than the standard Racing Spec valving if the rest of the car warrants it.

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

This kit is built for the Y32-chassis Infiniti Q45 across its 1991 to 1996 production run. Fitment is welding-type rather than bolt-in – the top mount is fabricated onto the factory strut tower during installation, so this is a workshop job rather than a driveway swap. Confirm your car is the Y32 generation before ordering, as later Q45 chassis use different mounting hardware.
