XYZ Racing Super Sport Coilovers — Infiniti M35 / M45 Y50 FUGA 4WD (Modified Rear Integrated) 2006-2010

The Y50 FUGA’s 4WD layout puts more hardware between the rear subframe and the body than the rear-drive M-badge cars sold outside Japan ever had to deal with, and the factory ride was tuned around that extra mass rather than around driver feedback. A Super Sport coilover kit swaps the compliant factory damping for a monotube setup with genuine adjustment range, aimed at owners who want the FUGA to respond like the sharper-handling saloon it can be without turning it into a track-only tool.

This is a fast-road-biased kit with weekend track use within reach, not a stripped-out race-only setup. For a 4WD saloon carrying this much drivetrain weight over the front and rear axles, that distinction matters: you want body control that survives a B-road at pace and a track day, without punishing the car (or your passengers) on the drive there.

What this coilover does for your 2006-2010 Infiniti M35 / M45 Y50 FUGA 4WD (Modified Rr Integrated)

Ride height adjustment lets you correct the stance and centre of gravity that the factory setup left needlessly high for a car this size, tightening turn-in without resorting to aggressive spring rates that would beat up the cabin over UK B-roads. The 36-way damping adjustment is the headline spec here – it means the same kit can be softened for a motorway commute and firmed up for a track session without swapping parts, which matters on a 4WD platform where body movement front and rear needs to be balanced rather than just stiffened everywhere. Because the FUGA carries more mechanical weight low in the chassis than a comparable RWD saloon, sharper damping control translates directly into less roll through direction changes and more confidence loading the front axle under trail-braking. Owners running this modified Rr Integrated rear-suspension spec should notice the biggest gains in how settled the rear end stays under load, rather than just a lower stance.

About the Super Sport coilover

Super Sport is XYZ Racing’s fast-road-to-weekend-track damper, built to remove the discomfort that comes from bumps and rough roads on a factory-tuned suspension setup. The monotube damper carries 36 levels of damping adjustment, giving a genuinely wide window between a compliant daily ride and a firmer track setting rather than a token handful of clicks either side of neutral. Ride height is independently adjustable, so lowering the car doesn’t force a single fixed damping rate on you. The design brief is explicit: a system that can be reset to suit different road conditions, rather than committing the car to one ride quality permanently. That flexibility is what separates a Super Sport-spec kit from a fixed fast-road spring-and-shock package – you’re buying adjustability as much as outright stiffness, which is the right trade-off for a car that most owners will still drive on ordinary roads between track outings.

Fitment for the Infiniti M35 / M45 Y50 FUGA 4WD (Modified Rr Integrated) (2006-2010)

This kit is built specifically for the Y50-chassis FUGA in 4WD guise with the modified rear-integrated suspension layout, covering the 2006-2010 production run. Chassis code IN09 identifies the correct fitment – confirm this against your V5C or chassis plate before ordering, since the FUGA was sold in multiple drivetrain and suspension configurations across this generation that this kit does not cover.
