XYZ Racing Pro Rally Coilovers — Infiniti Q45 (F50) CIMA welding 2001-2008

The F50-generation Q45’s weight sits high and far forward for a rear-wheel-drive saloon, and that mass transfer is exactly what a rally-spec big sedan has to manage the moment gravel, snow or loose surface throws load sideways through the chassis. XYZ Racing’s Pro Rally kit for the F50 is built around that reality: a professional, welded mounting solution rather than a bolt-in adapter, because a car this size wasn’t drawn up with rally-spec suspension travel in mind.

That welding-based install is the difference this kit is built for. Rather than clamping onto the factory strut towers and accepting whatever geometry that leaves you with, the Pro Rally kit is fitted after the body is modified to take it properly – the same route serious rally builds use when the base car is a repurposed road saloon rather than a homologated special.

What this coilover does for your 2001-2008 Infiniti Q45 (F50) CIMA Welding

Once the mounts are welded in and the kit is set, the F50 gains the wheel control a car of this weight needs on loose surfaces: a chassis that settles and turns rather than wallowing through direction changes, and a ride height and geometry chosen for the vehicle’s actual mass rather than a generic saloon assumption. On snow and gravel stages the payoff is predictable load transfer under braking and through direction changes, instead of the nose diving and the rear stepping out unpredictably that a heavy RWD saloon on stock suspension is prone to. Because the mounting is welded directly to a modified body rather than bolted through the original strut top, the geometry stays consistent even under the repeated hard hits a rally stage delivers – there’s no factory rubber mount flexing the picture out from under you lap after stage. For a car built for top-flight rally competition, that stability under repeated abuse is the whole point of specifying a professional-fit kit over an amateur bolt-in.

About the Pro Rally coilover

XYZ Racing builds its rally-gravel and snow suspension in two distinct forms, and this is the professional type: installed after the car’s body has been modified to accept it, rather than fitted directly to the original chassis mounting points the way an amateur-spec kit is. That distinction matters because a car built for genuine competition needs suspension geometry chosen for the job, not constrained by wherever the factory happened to put a strut tower. The welded-in mounting lets the kit be set up with the travel, angle and strength a rally stage demands, on a platform – the F50 Cima/Q45 – that was never engineered as a competition car from the factory. It’s the same philosophy XYZ Racing applies across its rally range: build to what the discipline needs first, then fit the car to that spec rather than the other way round.

Fitment for the Infiniti Q45 (F50) CIMA Welding (2001-2008)

This kit is specified for the F50-chassis Q45/Cima built between 2001 and 2008, and is supplied as the welding-fit professional variant rather than a direct bolt-on. Because the installation requires body modification to accept the mounts, fitting should be carried out by a shop experienced in rally-spec conversions on this chassis.
