XYZ Racing Drag Racing Coilovers — Infiniti Q45 (G50) Front top mount: 116mm / Front lower mount: φ20 1989-1997

The Q45’s VH45DE V8 sits in a heavy, full-size RWD saloon body, and getting that mass off the line without lighting up the rear tyres is the whole problem drag racing poses on this car. XYZ Racing’s Drag Racing coilover for the G50 is set up specifically for that moment – the 0 to 400 metre run – rather than for cornering load or ride comfort.

Where a road or track coilover spreads its damping curve across corner entry, mid-corner grip and exit, this kit concentrates on controlling weight transfer front to rear as the Q45 leaves the line. It’s the spec to run if your G50’s job on a given day is a straight line, not a circuit.

What this coilover does for your 1989-1997 Infiniti Q45

Because the kit lets you set front and rear ride height independently, you can shift static weight bias toward the rear axle before you even stage the car, loading the drive tyres ahead of the launch itself. That extra preload means less of the run is spent spinning; the compression at the rear contact patch comes on faster, cutting the idle time between the wheels turning and the Q45 actually moving. Once the car is rolling, the same height and damping settings that helped the getaway keep the body settled at speed rather than pitching onto the rear springs and unloading the nose. On a saloon this heavy, that composure at the top end matters as much as how it leaves the line.

About the Drag Racing coilover

XYZ Racing built this line specifically around the 0 to 400 metre run, and made it work across front-, rear- and four-wheel-drive platforms rather than tuning it for one drivetrain layout. The core idea is ride-height and damping settings that let the car redistribute weight between front and rear the instant the throttle goes down, instead of holding a fixed, corner-balanced setup the way a circuit coilover would. Pushing more load onto the driven axle at launch increases tyre compression at the contact patch, which is what actually puts power down instead of into wheelspin, and it shortens the dead time where the wheel is turning but the Q45 isn’t yet moving. That same weight management is what keeps the chassis settled once you’re up to speed, rather than letting the body’s mass keep working independently of the suspension after the initial hit. On the G50 specifically, that behaviour is set around the front top mount 116mm and front lower mount φ20 hardware this fitment uses.

Fitment for the Infiniti Q45 (1989-1997)

This kit fits the Infiniti Q45 built on the G50 chassis from 1989 to 1997, specified for a front top mount at 116mm and a front lower mount of φ20. Confirm those two front mounting dimensions against your car before ordering, since the G50 generation ran more than one mounting configuration across its production years.
