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

The G35 and G37 coupe’s FM-platform rear end carries a multi-link setup shared with the 350Z and 370Z it was built alongside, but the coupe’s extra kerb weight means the factory dampers give up sooner under repeated hard cornering – you feel it as rear-end float on corner exit and a softness through direction changes that gets worse as tyre temperature builds. This Top Sport kit is built specifically for the Rr FORK, Modified Rr Integrated rear mount used across the 2006-2014 G35/G37 coupe range, so the fork-type lower shock eye locates against the car’s own geometry rather than an aftermarket bracket doing the work.

Top Sport is XYZ Racing’s spec for owners who book the odd track day but still drive the car every week. It raises spring rate and damping over a standard road setup without turning the ride into something you dread on a motorway run home.

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

Fit this kit and the first thing you notice is how much less the rear squats under load – the G35/G37’s multi-link axle stops wandering through mid-corner direction changes because the increased damping controls body movement rather than reacting to it a beat late. Braking into a corner, the front end settles faster after the initial dive, which buys you a more predictable turn-in point lap after each session. The stiffer spring rate also cuts the roll that shows up on the VQ-engined coupe’s higher-speed sweepers, so the outside tyre keeps a more consistent contact patch instead of loading and unloading as the body rocks. Ride height is adjustable, which lets you correct the slight rake these cars pick up once the rear springs settle, and dial the stance back to something level for a road-legal MOT check.

About the Top Sport coilover

Top Sport steps damping force up by roughly 30 to 50 percent over XYZ Racing’s street-tuned setting, or alternatively runs a spring rate around 2kg/mm firmer, depending on which side of that balance suits the way you drive. That extra control is there to deal with poor surfaces as much as track kerbs – it absorbs the hit from a rough patch of tarmac or a sharper edge without kicking the body sideways, and it keeps the tyre loaded on the road rather than letting it skip. The valving comes directly from XYZ Racing’s own Top Sport programme, tuned around cars that get driven hard on both track and public road rather than one or the other. It’s built for owners who want a car that holds its line under aggressive inputs on a circuit day and still rides acceptably on the commute in between.

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

This kit is engineered for the Infiniti G35 and G37 coupe built between 2006 and 2014, specifically the Rr FORK, Modified Rr Integrated rear-mount configuration (chassis reference IN07). Confirm your car uses this rear mount type before ordering, as the fork-type lower eye is not interchangeable with other G35/G37 rear-suspension variants.
