XYZ Racing Super Sport Coilovers — Infiniti Q45 (Y33) welding 1997-2001

The Y33-generation Q45 was engineered as a comfortable, quiet, two-tonne RWD flagship, and its factory dampers reflect that brief: soft enough to smooth out a motorway expansion joint, soft enough that the VH45DE V8’s weight rolls the nose under hard braking and pushes wide mid-corner. The XYZ Racing Super Sport coilover kit for the Infiniti Q45 (Y33) WELDING, built for the 1997-2001 model years, replaces that factory setup with a damper designed to hold the car’s line without turning the ride brittle on the road home.

Height is adjustable independently of spring preload, so you can correct the Q45’s stance and corner weighting without sacrificing the compliance a car this size still needs on UK roads. Thirty-six clicks of damping adjustment move the car between a settled daily setting and a firmer one for a fast road session or a weekend track outing, all from the one kit.

What this coilover does for your 1997-2001 Infiniti Q45 (Y33) WELDING

A big RWD saloon like the Y33 lives or dies on how well it controls weight transfer, and that’s exactly where this kit earns its keep. The 36-way damping adjustment lets you firm up compression under braking so the nose stays level instead of diving into the front tyres, then back it off again for a smoother ride once you’re off the circuit. Independent ride height adjustment means you can drop the Q45’s centre of gravity and correct any nose-heavy stance from the V8 up front, improving turn-in without resorting to stiffer springs alone. Because the kit is specified in the welded top-mount (WELDING) configuration for this chassis, installation follows the fitment this generation of Q45 actually needs, rather than a generic pillow-ball adaptation. The net result on the 1997-2001 Q45 is a car that changes direction with less roll and less nose-dive, while still being usable for the drive to and from the track.

About the Super Sport coilover

The Super Sport damper was built to solve a specific problem: factory ride quality that falls apart the moment the road gets rough or the pace picks up. It carries independently adjustable ride height, so lowering the car doesn’t force a compromise on preload, and 36-way damping adjustment covers everything from a comfortable commute to a stiffer, track-day-ready setting. XYZ Racing positions this range for weekend race use as well as daily driving, which is why the adjustment range is set wide rather than aimed purely at one end of the performance scale. For a heavy platform like the Q45, that breadth matters: the same kit can be softened for a long motorway run or firmed up for a session where body control counts more than comfort.

Fitment for the Infiniti Q45 (Y33) WELDING (1997-2001)

This kit is specified for the Y33-chassis Infiniti Q45 built between 1997 and 2001, in the WELDING top-mount fitment for this platform. Confirm your Q45 is a Y33-generation car within that build window before ordering, as coilover kits are chassis-specific and not shared across Q45 generations.
