XYZ Racing Pro Rally Coilovers — Infiniti M35 / M45 Y50 FUGA 2WD (Modified Rear Integrated) 2004-2009

The Y50-generation Infiniti M35 / M45 – sold in its home market as the Nissan Fuga – is a heavy, rear-driven three-box saloon that nobody designed with a gravel stage in mind. That’s precisely the gap this Pro Rally coilover kit is built to close on the modified-rear-integrated version of the car: the rear end has already been reworked to accept non-standard pickup points, and the standard damper simply has nowhere to bolt. This kit is machined to match that altered geometry rather than fight it.

For the Infiniti M35 / M45 running full loose-surface competition, that means suspension hardware sized for real wheel travel over ruts and compressions, not a fast-road compromise wearing a rally badge. It’s built around the reality of a big saloon carrying its weight low and rearward under braking into a hairpin, and it’s set up for crews running top-flight rally competition rather than the odd forest blast.

What this coilover does for your 2004-2009 Infiniti M35 / M45 Y50 FUGA 2WD (Modified Rr Integrated)

Fitted to the modified rear-integrated chassis, this coilover gives the rear axle a mounting interface purpose-matched to the reworked subframe rather than an adapted road part, which keeps camber and toe stable as the suspension cycles through big compressions. Ride height is adjustable independently of spring preload, so you can set the M35 / M45’s stance to clear ruts and crown roads without giving up the geometry the rear-end modification was built around. On a car this heavy, controlling body roll and pitch under trail-braking into a loose corner matters more than outright stiffness, and the kit is calibrated with that mass in mind rather than for a lighter hatchback platform. The result on gravel and snow is a rear end that stays planted and predictable as load transfers, instead of skating once the surface breaks away.

About the Pro Rally coilover

XYZ Racing splits its rally-spec suspension into two distinct builds, and this is the second of them. One version bolts straight to an unmodified chassis for cars still running factory mounting points – an amateur-level fit. The other, which this kit belongs to, is designed specifically for cars whose bodyshell has already been altered to take rally-spec suspension geometry: a professional-level build for a car that’s had genuine structural work done to its rear end. Because the Y50 Fuga isn’t a common rally base, this kit is built around the modified mounting points that conversion requires rather than assuming a stock subframe, with construction aimed at holding up to repeated gravel and snow-stage abuse rather than tarmac use alone.

Fitment for the Infiniti M35 / M45 Y50 FUGA 2WD (Modified Rr Integrated) (2004-2009)

This kit is spec’d for the IN08 chassis code covering Infiniti M35 / M45 (Nissan Fuga Y50) models from 2004 to 2009, in 2WD form with the modified rear-integrated rear end. It is not intended for cars still running the unmodified factory rear subframe – confirm your car has already had that rear-end work carried out before ordering.
