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

The Y50-generation M35 / M45 carries its V6 and drivetrain over a rear axle that was tuned for motorway comfort, not for putting power down in the first sixty feet. Under hard launch, that stock rear geometry lets weight roll away from the driven wheels at exactly the moment you need it planted there. The XYZ Racing Drag Racing coilover for this 2WD, Modified Rr Integrated FUGA is built around a single job: 0-400m runs, repeated, without the rear end going light.

Where a road or track coilover splits its attention between corner entry and mid-corner balance, this kit is set up purely for straight-line launch and weight management. It lets you shift the car’s front-to-rear balance towards the driven axle in the instant of launch, rather than fighting the FUGA’s factory ride height and spring rate all the way down the strip.

What this coilover does for your 2004-2009 Infiniti M35 / M45

Fitted to the 2WD FUGA platform, the kit’s height and preload adjustment let you load the rear axle before you leave the line, so the driven tyres compress harder into the tarmac instead of unloading under torque. That extra compression on the rear contact patch cuts the amount of time the tyre spends spinning free at launch, which is the difference between a clean 60-foot time and a smoky, wheel-spinning start. Because the geometry change works with the M35 / M45’s factory rear multi-link rather than against it, the car settles into a more stable line at speed instead of wandering as power comes on. The adjustable ride height also lets you drop the nose slightly to manage front-end lift under acceleration, keeping the steering axle in more consistent contact through the run.

About the Drag Racing coilover

XYZ Racing’s Drag Racing range is built specifically for 0-400m competition across FWD, RWD and 4WD platforms, and the kit for this FUGA follows the same brief. The core idea is weight transfer control: the coilover’s adjustment lets you deliberately shift the car’s front-rear balance towards whichever axle is doing the driving, so the driven tyres see more instantaneous compression the moment power goes down. On a 2WD FUGA that means loading the rear during launch prep rather than waiting for the factory spring rate to settle naturally under torque. Less time with a tyre spinning free means a more stable, more repeatable run, which is the whole point of a setup tuned specifically for the strip rather than a general lowering kit. Construction follows XYZ Racing’s coilover format of separate spring and damper assemblies with external ride height adjustment, so the car can be reset between passes without stripping the suspension down.

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

This kit is built for the Y50-chassis Infiniti M35 and M45 – sold in Japan as the Nissan Fuga – across the 2004 to 2009 model years. It’s specific to the 2WD driveline with the modified rear integrated-link mount, so confirm your FUGA runs that exact rear configuration before ordering. Chassis code IN08 covers this fitment in our system; cross-check it against your V5C or Infiniti build sheet if you’re unsure which Y50 variant you have.
