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

The Y50-generation Infiniti M35 / M45, sold at home as the Nissan/Infiniti FUGA, is a large, heavy executive saloon, and running it in 4WD "Modified Rr Integrated" specification means the rear subframe geometry has already been reworked away from the standard rear-wheel-drive layout. Carrying that mass across a gravel stage’s constant surface changes is exactly what the XYZ Racing Gravel Rally coilover is built to control. Where a road coilover is tuned to filter out bumps, this kit is set up to keep the wheel in contact with a surface that is never flat for more than a second.

For gravel-stage rally use in a car this size, wheel travel and shaft speed matter more than outright spring rate on paper. The Gravel Rally coilover gives the M35 / M45 the stroke and damping range to absorb compressions at speed without bottoming out, while keeping the nose settled through fast, loose corners.

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

Fitted to the Y50 platform, this coilover changes how the car behaves the moment the tarmac ends. The long-stroke damper and matched long spring keep the wheel tracking through compressions that would send the standard M35 / M45 suspension into its bump stops, meaning less energy transferred into the chassis and more of it absorbed at the corner. Inverted-tube construction keeps the working shaft shielded from the sand, grit and stone-chip a gravel stage throws up, which matters on a saloon that was never designed with rally use in mind. The result is a chassis that stays composed under the cornering G-force of fast direction changes, rather than one fighting its own suspension travel. Ride height and damping are both adjustable, so the setup can be leaned toward flat-out, high-speed stages or tighter, technical gravel depending on the event.

About the Gravel Rally coilover

XYZ Racing’s Gravel Rally coilover is built specifically for rally and rallycross use, where the surface underneath the car changes constantly and aggressively within a single stage. Sandstone, packed snow and loose silt each load a damper differently, so the unit uses an inverted-tube layout designed to keep working consistently as those conditions shift. Stroke length and spring length are both extended well beyond a road-going coilover, giving the damper the travel to soak up chassis vibration and the high-frequency hits of a bouncy, high-speed gravel road without losing control of the wheel. Spring rates come from data gathered with an active rally racing team rather than picked on paper, so the base tune reflects what holds up across a full stage, not just a single hot lap.

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

This kit is built for the Y50-chassis Infiniti M35 / M45, sold in Japan as the FUGA, across the 2006 to 2010 production run in 4WD guise with the Modified Rr Integrated rear-end specification. Confirm your car matches this chassis and drivetrain before ordering, as the standard rear-wheel-drive Y50 uses a different rear setup.
