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

The G37’s kerb weight is the first thing that shows up in the data once you start lapping it properly – this is a near-1,700kg 2+2 GT car carrying a VQ37VHR V6 over the front axle, and the factory strut and shock package was tuned to manage that mass gently, not to control it under trail-braking into an apex. XYZ Racing’s Racing Spec coilover replaces that compromise with a damper built specifically around circuit-speed loads, engineered for the IN07-1 chassis code covering the Coupe and Convertible built with the modified rear integrated link setup.

Racing Spec sits at the sharp end of the XYZ Racing range, aimed at owners running serious track and time-attack sessions rather than the occasional trackday blast. On a car this heavy, that means damping that can arrest weight transfer under hard braking and hold the line mid-corner without the float the standard G37 setup allows once lap times start dropping.

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

Fitted to a G37 with the modified rear integrated link already in place, this kit lets you correct the nose-heavy balance the VQ37VHR imposes – stiffer, better-controlled front damping cuts the dive under braking that otherwise loads the outside front tyre too early. At the rear, the coilover is matched to the integrated link geometry rather than fighting it, so the axle stays settled through direction changes instead of stepping out unpredictably on corner exit. Ride height adjustment lets you set corner weights properly for a Coupe or Convertible running on slicks or semi-slicks, and the reduced body roll means less of the G37’s mass shifting around mid-corner, which is where this car loses time against lighter FM-platform rivals. The net effect on a heavy GT car like this is a chassis that turns in on command instead of resisting it.

About the Racing Spec coilover

Racing Spec is XYZ Racing’s dedicated circuit-racing damper, and its baseline valving isn’t a desk exercise – the settings come out of real racing programmes, including WTCC-level competition, where the same damper family has been run under race conditions. That background is why the unit is built to hold a consistent damping curve under sustained track abuse rather than fading as oil temperatures climb. For cars carrying heavier modification – factory racing builds or A-class competition cars with significant upgrades elsewhere in the drivetrain and aerodynamics – XYZ Racing also offers a bespoke shock absorber service: send over the spec of what else has been changed on the car and which circuit it’s built for, and the damper can be built around that specific combination rather than a generic track setting. For a G37 already running the modified rear integrated link, that custom-build route is worth considering once the rest of the car moves further from stock.

Fitment for the Infiniti G37 Coupe Convertible USA (Modified Rr Integrated) (2009-2013)

This kit is built to chassis code IN07-1, covering the Infiniti G37 Coupe and Convertible sold in the USA market across the 2009-2013 model years. It’s specced for cars that have already had the rear suspension modified with the integrated link setup referenced in the fitment name – check your car’s rear end matches that configuration before ordering, since the geometry this coilover is tuned around depends on it.
