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

The G50 Q45’s kerb weight and nose-heavy 4.5-litre V8 layout put more load through the front axle under compression than most gravel-stage builds ever have to manage, and that’s the problem the XYZ Racing Gravel Rally coilover for the Q45 is built to solve. Matched to this chassis’ 116mm front top mount and φ20 front lower mount, the kit keeps front geometry correct when the car is loaded sideways into a rutted compression at speed.

This is a Gravel Rally-specification damper, built for stages and rallycross events rather than tarmac driving, where the surface changes metre to metre and the shock has to keep working through repeated hard hits without fading. On a car as heavy as the Q45, that consistency under load matters more than outright spring rate.

What this coilover does for your 1989-1997 Infiniti Q45

Fit this coilover to a 1989-1997 Infiniti Q45 and the biggest change you’ll feel is control through the front end when the surface breaks up. The long stroke and long spring absorb chassis vibration from a high-speed bouncy road instead of transmitting it straight into the chassis, which on a car this heavy stops the nose from crashing into its bump stops over repeated compressions. Cornering load is the other half of the job – gravel and rallycross both put extreme G-force through the outside dampers mid-corner, and the inverted tube construction is there specifically to keep working through that loading rather than losing damping consistency as the shock heats up over a stage. For a G50 running gravel events, that translates into a front end that stays predictable stage after stage, rather than one that gets vague as the dampers work harder.

About the Gravel Rally coilover

XYZ Racing’s Gravel Rally coilover is built specifically for rally and rallycross use, where gravel-stage conditions are about as aggressive as motorsport surfaces get – sandstone, snow and silt all inside the same event, sometimes the same stage. The design uses an inverted damper tube, which keeps the working rod protected from the debris a gravel stage throws up and holds damping performance steady as conditions change underneath the car. Stroke length and spring length are both extended beyond a tarmac-focused kit, giving the damper room to absorb chassis vibration and soak up repeated high-speed compressions without bottoming out. Every spring rate offered in this range has been set by testing with an XYZ Racing-affiliated rally team, rather than derived from road-car data, so the rates reflect what a gravel car actually needs rather than a generalised suspension calculation.

Fitment for the Infiniti Q45 (1989-1997)

This kit is specified for the G50-generation Infiniti Q45 built between 1989 and 1997, matched to a front top mount of 116mm and a front lower mount diameter of φ20. Confirm these two front mounting dimensions against your own car before ordering, as G50 production spanned more than one front suspension specification.
