XYZ Racing Street Advanced Coilovers — Infiniti G35/G37/G37 COUPE Rear FORK (Modified Rear Integrated) 2006-2014

The G35 and G37 coupe’s rear end runs a multi-link setup that, once you start pushing the factory dampers, telegraphs every mid-corner bump straight through the seat. On cars running the modified Rr Integrated fork conversion, that rear geometry needs a damper that can actually keep pace with the change, not just bolt up to it. The Street Advanced kit is built for exactly that gap between a daily-driven G-series and one that sees regular track days.

This isn’t a track-only setup. It’s built for the owner who commutes in the G35 or G37 through the week and wants it composed on a Saturday morning B-road or the odd trackday, without living with a harsh ride the other five days.

What this coilover kit does for your 2006-2014 Infiniti G35/G37/G37 COUPE Rr FORK (Modified Rr Integrated)

With 720 damping adjustment positions on board, you get genuinely usable range rather than a handful of clicks either side of "default" – soften it off for the motorway commute, wind it up for a trackday without swapping parts. On the modified Rr Integrated fork rear end specifically, that adjustability matters more than usual: the fork conversion changes how load transfers through the rear during hard cornering, and a damper you can actually tune keeps the rear planted instead of hopping over mid-corner ridges. Ride height is adjustable independently of spring preload, so you can correct the stance changes that often come with a rear-end modification like this without stacking the springs to get there. The result on the G35/G37 coupe is a car that turns in with less of the initial body roll the factory setup allows, and holds its line through a fast direction change instead of wallowing.

About the Street Advanced coilover

XYZ Racing developed the Street Advanced line over several years specifically to sit between a comfort-biased street coilover and a dedicated race unit, and it’s become the brand’s most widely fitted product as a result. The damping valving has been proven across race series worldwide before being carried over into this street-tuned build, so the hardware underneath the adjustability isn’t detuned from what XYZ runs in competition. The 720-way adjustment count comes from a fine-pitch valving mechanism rather than a handful of coarse detents, which is what lets the kit cover both a comfortable commute and a stiffened track setting off the same shock body. XYZ positions this kit for exactly two use cases: regular road driving and occasional track days, rather than trying to be a everyday-comfort product or a dedicated race product stretched to cover both. For a driver who wants to feel the car sharpen up without needing a second set of dampers for trackdays, that’s the brief this kit is built to.

Fitment for the Infiniti G35/G37/G37 COUPE Rr FORK (Modified Rr Integrated) (2006-2014)

This kit is built for the Infiniti G35 and G37, including the G37 coupe body, across the 2006 to 2014 production run, specifically for cars running the modified Rr Integrated rear fork conversion (chassis reference IN07). If your G35 or G37 hasn’t had this rear-end fork modification carried out, check with a fitment specialist before ordering, as this kit is matched to the altered rear geometry rather than the stock rear end.
