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

The Y50 Fuga’s ATTESA-based 4WD driveline and its near-two-tonne executive-saloon mass make it an unlikely rally car, and that’s precisely why this kit exists as a modified-rear-integrated build rather than a straight bolt-in. A lighter, front-drive hatch can often take a rally coilover onto its factory mounting points; the Fuga’s rear-biased weight transfer and the packaging squeeze around its 4WD hardware mean the rear subframe and mounts have to be reworked before a damper of this length and travel can do useful work on loose surfaces.

Pro Rally sits at the top of the XYZ Racing rally line-up, built for gravel and snow stages rather than fast-road driving. On a car this heavy, that means damping calibrated to keep the tyre loaded through compressions and crests instead of skipping across them, with the rear geometry set up specifically for the modified chassis this kit is designed to run on.

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

On a car carrying this much weight over a 4WD driveline, the rear axle is doing more work than the spec sheet suggests, and unmodified rear geometry runs out of usable travel fast once you’re off tarmac. Because this kit assumes the rear has already been integrated into a modified body structure, the damper and spring can sit at ratios that keep the rear wheels tracking the surface through compression rather than deflecting off it, which is what actually controls a heavy saloon on a rutted stage. The front end benefits from the same logic: with the 4WD system’s extra driveline mass up front, spring rates that account for that load stop the nose diving into compressions and losing steering response mid-corner. Ride height adjustment lets you set stance and geometry to match the stage – or the class regs you’re building the car to.

About the Pro Rally coilover

XYZ Racing splits its gravel and snow suspension into two distinct builds, and it’s worth knowing which one you’re buying. The first is an amateur-grade setup that bolts straight onto the stock chassis and mounting points, aimed at cars that haven’t been structurally modified. The second, and the one specified here, is the professional route: a kit designed to be fitted only after the car’s body and rear end have already been modified to accept it, which is what "Modified Rr Integrated" refers to in this listing. That distinction matters because a professional-spec rally suspension can use geometry and mounting points a stock chassis simply can’t offer, which is how competition teams actually run these cars rather than adapting rally hardware to an unmodified shell. For the Fuga specifically, that rear integration work is what makes a genuine rally-spec damper viable on a chassis never designed for one.

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

This kit is built for the Y50-generation Infiniti M35 / M45 (JDM-market Fuga), chassis code IN09, across the 2006-2010 production run, and specifically for 4WD cars with a modified rear end. Because it’s the professional-integration spec, it’s not intended for a stock, unmodified Y50 4WD shell – confirm your rear subframe and mounting points have already been reworked to rally spec before ordering.
