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

The F50-generation Q45 carries its kerb weight north of 1.8 tonnes through a double-wishbone front end and multi-link rear that was tuned for a quiet boulevard ride, not for holding a line at nine-tenths into a hairpin. XYZ Racing’s Racing Spec coilover exists to close that gap, giving a big V8 saloon the body control it needs when the road opens into a circuit.

For owners running a modified Q45 F50 – CIMA Welding included – on serious track and time-attack days, this sits at the top of XYZ’s coilover range: settings built around circuit use rather than a fast-road compromise.

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

Fitted to the F50, the Racing Spec kit tightens up the wallow that comes with a heavy, long-wheelbase saloon carrying a big V8 up front. Dive under braking is reined in, squat off the throttle is reduced, and the multi-link rear stays planted through direction changes instead of following the body’s momentum a beat late. Ride height drops to a track-appropriate stance, which lowers the centre of gravity and cuts the roll this chassis is naturally prone to. The result is a Q45 that turns in with more precision than its factory geometry was ever set up to deliver, and holds that composure lap after lap of hard use rather than fading as the session goes on.

About the Racing Spec coilover

XYZ’s Racing Spec damper is the circuit-focused end of the range, with its baseline settings drawn from direct involvement in touring car racing, including WTCC competition. That pedigree shapes how the damper responds under the kind of repeated, high-load inputs a track day throws at a car this heavy – hard braking zones, fast direction changes, sustained cornering loads. For cars pushed further still, XYZ can build genuinely bespoke shock absorbers for heavily modified examples running factory-level or A-class racing specification. Owners in that position are asked to supply details of their car’s upgraded parts and the circuit they intend to run, so the damper can be built around that specific combination rather than a generic setting. It is a route built for the F50 owner who has already moved past bolt-on modifications and wants a chassis engineered to match.

This kit is built for the F50-chassis Infiniti Q45, sold in Japan as the Cima, across the full 2001 to 2008 production run. Confirm your car matches the F50 chassis code before ordering, as suspension geometry and mounting points changed between Q45 generations.
