XYZ Racing Top Sport Coilovers — Infiniti G35 2D (Modified Rear Integrated) 2002-2006

The G35 2D’s rear-biased weight distribution and the VQ35DE’s torque delivery put real load through the rear subframe the moment you get back on the throttle mid-corner, and the factory dampers were tuned for a comfortable daily rather than for holding that rear end flat. XYZ Racing’s Top Sport coilover kit for this Modified Rr Integrated fitment is built around that problem: a shock and spring package stiffened specifically for cars that see a track day now and then but still need to be liveable on the drive home.

For an owner running the G35 coupe on track days and fast B-roads alike, this is the middle ground between the soft factory setup and a full race spec – enough damping and spring rate to keep the chassis composed under load, without turning the ride into something you dread on a motorway commute.

What this coilover does for your 2002-2006 Infiniti G35 2D

Stepping up damping by roughly 30-50% over the standard setting – or fitting springs around 2kg/mm firmer than the street baseline – keeps the G35’s body flatter under trail-braking and mid-corner load, which matters on a chassis that will happily roll onto its outside rear tyre if you let it. That extra control reduces the shock body movement that eats into tyre contact patch on uneven surfaces, so the rear end stays planted through compressions and over kerbs instead of skipping. You get more usable grip out of the VQ35’s power on corner exit because the tyre is loaded consistently rather than hunting for traction as the suspension recovers from the last bump. On the road, the same settings tighten up body control under hard braking into a roundabout or a quick direction change, so the coupe feels like one connected unit rather than a nose and tail working against each other.

About the Top Sport coilover

Top Sport sits above XYZ Racing’s street-oriented ranges by taking damping up roughly 30 to 50 percent over a standard road setting, or alternatively firming the springs by around 2kg/mm, depending on which combination suits the car. That extra resistance is there to control the shock body through big hits – potholes, compressions, kerb strikes – rather than letting the suspension bottom out or bounce back unsettled. Keeping the shock body under control is what keeps the tyre pressed into the road surface, and that is where the traction gain actually comes from rather than any change to the tyre itself. The valving and spring combinations in this range are carried over from XYZ Racing’s own track-day and race programme, not a street kit simply turned up a notch. That gives the kit a bias toward stability under load – less float, less unwanted movement through the chassis – which is what makes it suited to drivers who want to run a track day and then drive home on the same set of coilovers, plus anyone who just drives their G35 hard on the road.

Fitment for the Infiniti G35 2D (2002-2006)

This kit is built specifically for the two-door G35 coupe, chassis code IN05, across the 2002 to 2006 model years, in the Modified Rr Integrated configuration. If your car falls within that build window and matches this rear-end spec, the kit is a direct fit without further adaptation.
