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

The Y50-generation M35/M45 (badged FUGA in its home market) carries a lot of saloon into a stage: a big VQ-series V6 up front, 4WD hardware underneath, and a kerb weight that punishes anything soft in the dampers the moment the road surface turns to broken chip-seal or wet gravel-edged tarmac. XYZ Racing’s Tarmac Rally coilover is built for exactly that mismatch – a heavy, powerful 4WD saloon asked to change direction fast on a surface that’s never quite flat.

This is the sealed-stage tarmac rally spec, not a fast-road or track-day compromise. Where a road coilover is tuned to iron out small imperfections, this kit is tuned to keep the M35/M45’s rear-integrated 4WD platform composed when a mid-corner bump, camber change or pothole tries to unsettle it at speed.

What this coilover does for your 2006-2010 Infiniti M35 / M45

On a car this size and weight, body control under compression is the whole game. The damping settings XYZ Racing carries over from its own tarmac rally programme are built to catch a big hit – a crest, a lip, a rut cut by the car in front – without the body pitching or the rear axle skipping sideways. That matters more on the Y50’s modified rear-integrated 4WD layout than on a lighter FWD chassis, because there’s more mass for the dampers to control through each compression-rebound cycle. The result on your car is a rear axle that stays loaded and tracking rather than hopping, and a front end that keeps its line into off-camber corners instead of pushing wide. You also get the stance and ride-height adjustment to correct the nose-down or squat that stock springs develop once a heavy V6 saloon starts absorbing repeated stage-speed impacts.

About the Tarmac Rally coilover

XYZ Racing developed this damper specifically to absorb the impact of broken and uneven pavement rather than to filter out small, smooth-road inputs. The valving is set to soak up a hard hit across a big bump without letting that energy bounce straight back into the body – suppressing the shock that would otherwise unsettle the chassis and, just as importantly, keeping the tyre loaded against the road so it can keep generating grip through the impact rather than skipping across it. That combination – controlled body movement plus a tyre that stays planted – is what gives the car predictable handling when the surface stops cooperating. Every setting in this spec comes directly from XYZ Racing’s own tarmac rally programme, carried over rather than reworked for showroom comfort, so the character of the damper on your M35/M45 is the same character it has on a stage car.

Fitment for the Infiniti M35 / M45 (2006-2010)

This kit is built for the Y50-chassis M35/M45 (JDM FUGA) across the 2006-2010 build years, specifically for the 4WD variant with modified rear-integrated suspension – chassis code IN09. Confirm your car matches this 4WD, rear-integrated configuration before ordering, as the Y50 range spans multiple drivetrain layouts.
