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

The Y50 FUGA’s four-wheel-drive layout puts extra hardware and mass over the rear axle, and on the standard dampers that translates into a car that never quite settles through a compression-and-release sequence the way a rear-drive M-series does. XYZ Racing’s Street Advanced coilovers are built to correct that without turning the car into something you dread commuting in.

This is the mid-tier Street Advanced spec, which XYZ positions between comfort-first and full track kit: enough adjustment range to sharpen the FUGA’s front-to-rear balance on a Sunday blast, without giving up the compliance you need for the school run in a big 4WD saloon.

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

With 720 damping increments to work through, you can walk the front and rear circuits independently until the nose-heavy 4WD platform stops pushing wide on turn-in and instead loads progressively through the outside front tyre. Firming the rear a few clicks helps settle the extra unsprung weight the AWD hardware adds, cutting the float you’d otherwise feel over motorway expansion joints and mid-corner ridges. Ride height is adjustable independently of that damping curve, so you can drop the FUGA’s stance without pre-loading the springs into a harsher static setting than you actually want. Because the kit is built around this specific Modified Rr Integrated fitment, the rear geometry stays correct through its travel instead of fighting the AWD subframe mounting points the way a generic universal kit would.

About the Street Advanced coilover

XYZ Racing developed the Street Advanced line over several seasons of its factory motorsport programme, running prototypes through international racing before signing off the production spec – the same 720-way damping architecture seen in this kit traces back to that testing. It sits deliberately between the brand’s comfort-biased road kits and its dedicated track ranges: XYZ built it for drivers who split their time between everyday roads and the occasional track day rather than committing fully to one or the other. Construction follows XYZ’s monotube-based platform, which resists the fade you get from oil aeration on longer, harder drives better than a twin-tube design. The 720-way adjuster lets you bias the setup toward either use case on demand rather than locking you into a single compromise. For a Y50 FUGA owner, that range matters more than on a lighter, rear-drive-only chassis, since the AWD driveline mass shifts where the damping work actually needs to happen.

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

This kit is engineered specifically for the Y50-chassis Infiniti M35 and M45 (badged FUGA in its home market) built between 2006 and 2010 in four-wheel-drive form, using the modified rear-integrated mounting configuration rather than the standard rear-drive geometry. Confirm your car is the AWD variant before ordering, as the rear damper and spring mounting differs from the rear-drive Y50.
