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

The F50-generation Q45’s problem was never grip, it was ride quality – Nissan’s original air suspension and later steel-sprung setups were tuned soft for a Japanese luxury saloon, not for a driver who wants to load the front end on a B-road and trust it stays flat. Swap that stock geometry for XYZ Racing Super Sport coilovers and the car keeps its long-wheelbase composure but stops wallowing through direction changes.

This kit targets fast-road use with enough range to work a weekend track day too, without turning the Q45 into something that beats up your spine on the commute.

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

Ride height is fully adjustable front and rear, so you can drop the F50’s factory stance to clean up the wheel-to-arch gap or correct the nose-up rake some cars settle into as the original springs age. The 36-way damping adjustment is the bigger deal on a car this size: soften it off and the big saloon rides civilly over UK B-road surfaces, firm it up and body roll through a fast sweeper drops noticeably compared with the factory dampers. Because you’re setting both ride height and damping independently, you can correct the CIMA’s tendency to sit nose-heavy under braking without turning the rear into a pogo stick. For a car that’s rarely been given aftermarket suspension attention, this is the first real chance to make the chassis match the VH45DE’s shove.

About the Super Sport coilover

XYZ’s Super Sport damper is built to take the harshness out of bumps and rough surfaces that a stock damper simply transmits straight into the cabin. It carries 36-way dampening adjustment, letting you retune compression and rebound as conditions change rather than living with one compromise setting, and ride height adjustment is built into the same unit so stance and function are set together, not separately. XYZ pitches this damper for both weekend racing and daily use, which is exactly the split-purpose brief the F50 Q45 needs – a car heavy enough to need real damping control, but one most owners will still drive to work on Monday. The adjustment range is wide enough to go from a comfortable daily setting to a firmer track-day tune without swapping hardware.

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

This kit is built specifically for the F50-chassis Q45, including the CIMA Welding variant, across the 2001-2008 production run. Confirm your car sits within that chassis code and year span before ordering, as F50 geometry differs from earlier Q45 generations.
