XYZ Racing Street Advanced Coilovers — Infiniti G37 COUPE CONVERTIBLE USA (Modified Rear Integrated) 2009-2013

The G37’s independent rear end was never designed with a fixed damper rate in mind, and on the Street Advanced kit’s modified integrated rear mounting, that geometry gets a coilover that can actually track the car’s mood – commuting one day, a B-road blast the next. This is the platform’s most-fitted spec in the range for a reason: it covers daily comfort and a spirited back road without asking the owner to pick a lane.

For the G37 Coupe, Convertible or the USA-spec variants covered by this modified Rr-integrated fitment, ride height and damping stay adjustable rather than locked to a single compromise, which matters on a chassis that carries real weight over the front axle and needs the rear settled to put that VQ-series power down cleanly out of a corner.

What this coilover does for your 2009-2013 Infiniti G37 COUPE CONVERTIBLE USA (Modified Rr Integrated)

Ride height drops through threaded body adjustment, tightening the G37’s stance and lowering its centre of gravity without touching the spring’s working range. Damping is independently adjustable across 720 distinct positions, giving enough resolution to soften the front for a motorway commute and firm the rear for a track day without swapping parts. Owners running these fitments typically report reduced body roll through direction changes and better weight transfer control under braking, where the G37’s nose-heavy front end tends to push if the suspension is left soft. Because the rear mounting is factory-integrated rather than retrofitted, the geometry stays true to the car’s original pickup points, so alignment settings hold rather than drifting after the first hard drive.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s core product, refined over several years of development and proven across the brand’s international racing programme before being brought to road-going kits. It’s built specifically to bridge everyday road use and occasional track days rather than specialise in one or the other. The defining feature is 720-way damping adjustment, giving a far finer resolution than basic single- or multi-stage coilovers, so the rebound and compression characteristics can be tuned incrementally rather than in coarse steps. That range is what lets one kit serve a driver who wants a comfortable commute in the week and a firmer, flatter setup for a weekend track outing, instead of forcing a single fixed compromise. XYZ position it as the kit for anyone chasing genuine speed and control from their road car, and the adjustment count is the mechanism that makes both ends of that brief achievable from the same hardware.
