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

The F50-generation Q45 carries real weight – a naturally aspirated V8 in a full-size, rear-wheel-drive luxury saloon shell – which is exactly why standard dampers give up first when the road turns to broken tarmac. XYZ Racing’s Tarmac Rally coilover for the Infiniti Q45 (F50) CIMA Welding, covering 2001-2008 cars, is set up to control that mass through the compressions, ruts and blind crests a closed-road stage throws at it, not to shave tenths on a smooth circuit.

This is a sealed-stage tool first. The damping is calibrated to absorb the hit from a big bump without kicking the body sideways, so the tyre stays loaded into the next braking zone instead of skipping across the surface. On a car this heavy, that control is what turns an unpredictable stage car into one you can actually place on the road.

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

Fit this coilover and the Q45’s biggest handicap on a stage – its mass working against the suspension over rough, uneven tarmac – stops dictating your pace notes. The damper absorbs the shock of a big compression rather than transmitting it straight into the chassis, which keeps the body settled through a sequence of crests instead of pattering and unloading the outside tyre. That translates directly into traction: more of the contact patch stays pressed into the road surface through direction changes, which matters more on a car carrying this much weight than it does on a lighter hatch. The result is a Q45 that holds its line through mid-corner bumps rather than getting deflected off it, and a driver who can trust the car’s stability enough to keep committing to the next braking point.

About the Tarmac Rally coilover

XYZ Racing built the Tarmac Rally line specifically for sealed-stage work on broken, uneven surfaces rather than for smooth-circuit lapping. The valving is set to absorb the impact of rough pavement and big compressions without letting that energy translate straight into body shock, so the suspension is doing the work the chassis would otherwise have to absorb itself. That same absorption is what keeps the tyre’s contact patch loaded and traction consistent, which is the difference between a car that stays composed over a crest and one that skips wide off it. The overall aim is stability – a platform that behaves the same way stage after stage, so the driver isn’t relearning the car’s balance every time the surface changes underneath it. The settings supplied with this coilover come directly from XYZ Racing’s own Tarmac Rally programme, carried over from stage experience rather than derived on a bench.

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

This coilover is built for the F50-chassis Q45, badged CIMA Welding, across the full 2001-2008 production run. Confirm your car sits within that chassis code and year span before ordering, as F50 running gear was not shared with earlier or later Q45 generations.
