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

The XYZ Racing Gravel Rally coilover for the Infiniti Q45 (F50) CIMA WELDING addresses a problem few F50 owners ever expect to have: keeping a full-size, near two-tonne luxury saloon composed over broken, high-speed gravel instead of smooth tarmac. This is a car built around isolation and long-distance comfort, and the stock damping simply runs out of ideas the moment the surface turns loose and unpredictable underneath it.

Built for gravel-stage rally and rallycross rather than circuit lapping, this kit trades short-travel stiffness for stroke length and control. It gives the Q45’s substantial mass somewhere to go when a compression hits hard, rather than transmitting that hit straight through the chassis and unsettling the car mid-corner.

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

On a car this heavy, wheel control over rough ground is the difference between a clean stage run and a spin. The inverted-tube damper body used in this kit resists the flex a conventional tube struggles with once the F50’s mass loads the suspension hard over crests and compressions, so the piston keeps tracking true instead of binding. Long-stroke travel and long free-length springs give the wheel somewhere to go when the surface drops away beneath it, soaking up the kind of chassis vibration a saloon-tuned factory damper was never asked to handle. Through fast direction changes, that extended stroke also buys the tyre time to find grip again after a compression rather than skipping across the surface unloaded. The result on the Q45 is a car that stays planted and predictable when the road turns to gravel, sand or snow instead of loading up and pushing wide.

About the Gravel Rally coilover

XYZ Racing developed the Gravel Rally line specifically for rally and rallycross use, where surface conditions are about as hostile as motorsport gets and the damper carries more of the workload than in almost any other discipline. The inverted-tube layout was chosen to cope with the range of surfaces a single stage can throw at a car – loose sandstone, packed snow, fine silt – each loading the damper differently. Stroke length and spring free length are both extended well beyond a road or circuit-focused build, giving the suspension the travel to absorb chassis vibration and repeated hard hits from a bumpy, high-speed surface without bottoming out. That extra travel also matters under the sustained lateral loads of a fast gravel corner, where the outside damper has to keep working through the slide rather than topping or bottoming mid-turn. Spring rates across the range were set and proven by an active rally racing team rather than calculated on paper alone, so the starting spec has already done the job it is sold to do.

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

This kit is specced for the F50-chassis Q45, built in Japan as the Nissan Cima and exported under the Infiniti Q45 nameplate, across its full 2001 to 2008 production run. Confirm your car sits within that window before ordering, since the F50 shares its badge with earlier and later Q45 generations that use different suspension hardware. If your CIMA WELDING specification differs from a standard F50, check ride height and corner weight against your own logbook figures before setting initial preload.
