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

The Infiniti Q45 F50 is a long-wheelbase, V8-engined saloon built to ride flat and quiet, not to hook up hard off a line. XYZ Racing’s Drag Racing coilover exists to undo that factory bias for the quarter-mile, shifting weight onto the rear tyres in the instant the car launches instead of letting the nose rise and the back end spin.

This is the type built for 0-400m straight-line work rather than circuit lapping, and it suits an F50 owner chasing consistent 60-foot times rather than lateral grip. Where a circuit-biased coilover is set up to fight body roll through a corner, this kit is set up purely for launch and weight transfer down a straight strip.

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

Fitted to the Q45 F50, this coilover changes how load moves between the front and rear axles the moment you release the clutch or brake-torque off the line. Instead of the standard suspension letting the nose rise and unload the rear tyres, the kit’s setup lets you bias ride height and damping so the back end squats and the rear contact patches load up under acceleration. That translates directly into shorter 60-foot times and fewer wheel-spin launches, because the tyre is compressed into the tarmac rather than skipping across it. On a heavy rear-wheel-drive saloon like the F50, where unloaded rear tyres are the single biggest limiter off the line, that extra compression is the difference between a clean launch and a bogged one.

About the Drag Racing coilover

XYZ Racing’s Drag Racing coilover is built specifically for 0-400m straight-line runs, and it’s engineered to work across FWD, RWD and 4WD platforms rather than one drivetrain layout. The core idea is instant weight transfer: as the car launches, the setup redistributes load between front and rear so the driven wheels, the ones actually putting power down through the transmission, get compressed harder into the road surface. That extra compression cuts the moment where a tyre is under-loaded and prone to spin, which is where quarter-mile runs are won or lost in the first few car-lengths. Because the geometry change happens the instant the car moves, not gradually as speed builds, the benefit shows up right where a drag run is decided, at the hit, rather than further down the strip. It’s a setup built around one manoeuvre, not an everyday ride-comfort compromise or a corner-carving remit.

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

This kit is specified for the Infiniti Q45, chassis code F50, across the 2001 to 2008 production run. It’s built to the F50’s own suspension geometry and mounting points, so confirm your car falls within that year span before ordering, as earlier and later Q45 generations use different chassis codes and hardware.
