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

For a big, nose-heavy F50 running on a factory setup that was tuned decades ago for comfort over control, body roll and vague turn-in are the two things owners notice first once the car has covered real mileage. The XYZ Racing Street Advanced coilover kit for the Q45 (F50) CIMA Welding addresses both, giving the driver a full-height and damping-adjustable platform without pushing the car into track-only stiffness.

Street Advanced sits between XYZ’s entry-level and full-race ranges, built for enthusiast road use and the occasional track day rather than a dedicated circuit weapon. On a car the size and weight of the F50, that middle ground matters: enough control to shore up the standard car’s soft, wallowy responses, without turning the daily commute into a chore.

What this coilover does for your 2001-2008 Infiniti Q45 (f50) CIMA Welding

Ride height is fully adjustable front and rear, so the Q45’s stance can be brought down to suit the owner’s preference without resorting to cut springs or spacers. Damping is adjustable through 720 increments, which on a car this size gives real range: firmer settings tighten up body control under load and reduce the front-end dive this generation Q45 is known for under braking, while softer settings keep the ride liveable for daily use. Because the kit is height- and damping-adjustable independently, corner weighting and stance can be dialled to match the F50’s factory weight bias rather than fighting it. The result on-road is a car that turns in with less lean and settles faster after a mid-corner bump, instead of continuing to float on the stock dampers.

About the Street Advanced coilover

Street Advanced is XYZ’s most widely fitted product, developed and refined over years of production and put through testing in international motorsport before being carried across to road-going applications. It’s built for exactly this kind of use case: a car that sees normal road driving most of the time with the occasional track day thrown in, rather than a car living permanently on a circuit. The 720-way damping adjustment is the headline spec – a granular enough range that an owner can find a setting for a comfortable commute and a separate setting for a spirited back-road run, then switch between them without re-setting the whole kit. XYZ position this as essential equipment for drivers who want more control and more speed than the standard suspension can offer, and the spec numbers back that up: this isn’t a fixed-rate budget kit, it’s a genuinely tunable platform.

Fitment for the Infiniti Q45 (f50) CIMA Welding (2001-2008)

This kit is engineered specifically for the F50-chassis Q45, sold in some markets as the CIMA Welding, covering model years 2001 to 2008. Confirm your car sits within that build range before ordering, since Nissan/Infiniti revised suspension geometry across F50 production runs.
