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

Rally-prepping a G37 doesn’t stop at the suspension mounts. The Coupe and Convertible’s rear end has to be cut and reworked before a proper stage-spec kit will sit correctly, which is exactly the build this Pro Rally coilover is designed around: a rear-integrated, modified-chassis fitment rather than a bolt-in swap onto the standard subframe.

That distinction matters because rally suspension only works if it’s mounted the way the stage demands. A kit built for an unmodified shell will flex and bind the moment the car sees a rutted gravel section or a snow-packed hairpin at speed. This Pro Rally spec is built for the G37 that’s already had that bodywork done, so the geometry stays correct when the car is loaded sideways over broken surfaces.

What this coilover does for your 2009-2013 Infiniti G37

On a rear-integrated G37, the rear axle is carrying loads the factory subframe was never asked to handle, so the kit’s construction has to keep the wheel doing its job instead of transmitting every impact straight into the chassis. Ride height and damping are set up around the reality of loose, uneven surfaces rather than smooth tarmac, giving the car predictable weight transfer when you’re working the throttle out of a hairpin rather than trailing off it. On a car this heavy through the nose, getting the rear end to load consistently over rough ground is what keeps the back axle following the front instead of stepping out unpredictably. Because the kit is matched to the modified rear structure, the geometry holds under the kind of repeated hard landings a stage produces, rather than degrading corner to corner.

About the Pro Rally coilover

XYZ Racing builds its gravel and snow rally suspension in two distinct forms, and this is the professional-specification version. Rather than bolting into the car’s original mounting points, it’s built for a G37 that has already had its rear end modified to accept it, which is what "professional type" means in XYZ’s own rally range. That’s a deliberate trade-off: the amateur-spec version keeps the standard chassis untouched for simpler installation, while this integrated version accepts the extra bodywork in exchange for suspension geometry that’s purpose-matched to the modified structure underneath. It’s aimed squarely at drivers running the G37 in top-flight rally competition rather than a fast road or occasional trackday car.

Fitment for the Infiniti G37 COUPE CONVERTIBLE USA (Modified Rr Integrated) (2009-2013)

This kit is specified for the USA-market Infiniti G37 Coupe and Convertible, chassis code IN07-1, built between 2009 and 2013, with the rear-integrated bodywork modification already carried out. Confirm your car matches this modified-chassis specification before ordering, as the standard, unmodified G37 uses a different kit in this range.
