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

The Y32-generation Q45 carries close to 1,700kg over a double-wishbone front end and multi-link rear that road testers in period rated as genuinely well sorted for a big Nissan-built luxury saloon – right up until the factory dampers start giving up body control under load. XYZ Racing’s Street Advanced coilover kit for the Infiniti Q45 (Y32) WELDING drops into that fixed-mount rear end and gives the car’s underlying chassis talent a damper and spring package that can actually keep pace with it.

Built for owners who want the Q45 sharper on a fast road without turning a comfortable luxury saloon into a stripped-out track special, the Street Advanced spec sits between comfort-led street kits and full competition coilovers. It’s suited to daily use, with enough adjustment range to firm things up for an occasional track day without swapping parts.

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

On a car this heavy, damping control matters more than outright stiffness. The 720-way damping adjustment lets you tune compression and rebound to settle the nose under braking without making the ride harsh over broken B-roads. Lowering the centre of gravity through the height-adjustable perches sharpens turn-in on a chassis that was already inclined to rotate cleanly for its size, and tighter control of body roll keeps the Q45’s considerable mass in check through direction changes. The result is a saloon that changes direction with less lean and settles faster after a mid-corner bump, without the harsh secondary ride you’d get from a fixed-rate aftermarket spring.

About the Street Advanced coilover

XYZ Racing developed the Street Advanced line over several seasons of motorsport feedback, refining it into the most widely fitted coilover in the range. The kit has been run and proven in racing worldwide before being tuned back for road use, which is why the damping characteristics feel controlled rather than raw. Street Advanced is pitched specifically at drivers who split their time between normal road use and the occasional track day, rather than committed racers, and the 720-way damping adjustment reflects that brief – enough range to move from a comfortable daily setting to a firmer track setting without needing a second kit. For a car like the Q45, built for effortless speed rather than outright aggression, that breadth of adjustment is the point: it lets the driver choose how sharp the ride gets rather than having the choice made for them.

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

This kit is built specifically for the Y32-chassis Infiniti Q45 sold from 1991 to 1996, in the WELDING mount configuration – meaning the rear top mount is designed for a fixed, welded-in installation rather than a pillow-ball adjustable plate. Confirm your car carries the Y32 chassis code before ordering, as mount hardware differs between Q45 variants.
