XYZ Racing Pro Rally Coilovers — Infiniti Q45 (G50) Front top mount: 116mm / Front lower mount: φ20 1989-1997

Nobody builds a full-size G50 Q45 for a rally stage by accident. At 1,700kg-plus with a longitudinal V8 and rear-wheel drive, the platform was never conceived for gravel or snow special stages, and Nissan’s original air-over-hydraulic Full-Active Suspension on this chassis is the first thing that comes off a car destined for that kind of abuse. The XYZ Racing Pro Rally coilover replaces that complexity with something a mechanic can actually service between stages.

This is a competition part, not a fast-road upgrade. It’s built for the specific front top mount (116mm) and front lower mount (φ20) geometry of the G50 Q45, and it’s aimed squarely at crews running this car in top-flight rally competition rather than road use.

What this coilover does for your 1989-1997 Infiniti Q45

Swapping out the factory active suspension for a mechanical coilover removes the failure points that end rally cars early: hydraulic lines, accumulator spheres, and control units that don’t take kindly to repeated compression cycles over rough terrain. In their place you get a suspension system whose ride height and damping characteristics are set by hand and stay set, stage after stage, in conditions where an electronic system would be fighting itself. On a chassis this heavy, controlling body movement over crests and through compressions matters more than outright stiffness, and a coilover built for rally use is tuned to keep the front tyres loaded rather than skipping across the surface. The correct front top mount and lower mount dimensions for the G50 mean the geometry the car left the factory with is preserved, so the rest of the front end – steering, driveshaft angles – isn’t fighting an incorrect ride height.

About the Pro Rally coilover

XYZ Racing splits its rally-specification suspension into two distinct build paths, because gravel and snow competition asks different questions of a chassis than a tarmac road car does. One path is designed to bolt in against the original chassis mounting points with no bodywork changes, aimed at amateur and clubman-level entries where the car still needs to be practical outside the stage. The other – the path this Q45 kit follows – is built for cars where the body has already been modified for competition, and the suspension is engineered to work with that modified structure rather than around it. That distinction matters for how the kit is specified and installed, and it’s why a Pro Rally coilover isn’t simply a stiffer version of a road kit; it’s built assuming the car around it has already been prepared to a professional competition standard.

Fitment for the Infiniti Q45 (1989-1997)

Specified for the G50-chassis Infiniti Q45, this kit is built to the front top mount (116mm) and front lower mount (φ20) dimensions unique to this generation. Confirm your car sits within the 1989-1997 production run before ordering, as G50 mounting points changed across the Q45’s model history.
