XYZ Racing Racing Spec Coilovers — Infiniti FX35/37 S51 4WD (Modified Rear Integrated) 2008-2013

The S51-generation FX35/37 carries close to two tonnes of VQ35/VQ37 V6 and ATTESA 4WD hardware low in the chassis, and the factory suspension was tuned for a comfortable crossover, not a car that gets pointed at an apex repeatedly. That mismatch is exactly what a Racing Spec kit is built to correct: damping calibrated for circuit loads rather than motorway compliance, matched to a rear-integrated mounting solution engineered around the S51’s multi-link rear end rather than bolted on as an afterthought.

XYZ Racing’s Racing Spec range sits at the top of the coilover line-up for a reason – it’s the spec built for time-attack and serious track sessions, where the car needs to hold a consistent line through a full session rather than just ride well on the school run. On the FX35/37, that means a damper that can actually manage the crossover’s mass transfer under braking and direction changes instead of being overwhelmed by it.

What these coilovers bring to your 2008-2013 Infiniti FX35/37

Fit this kit to a 2008-2013 FX35 or FX37 and the most immediate change is body control: the FX’s tall stance and soft factory springs give up a lot of contact patch to roll mid-corner, and a Racing Spec setup pulls that roll back in so the tyres stay loaded evenly through a fast direction change. Because the rear integrates directly with the S51’s multi-link geometry rather than relying on the softer factory bushings and mounts, rear-end response to steering and throttle inputs sharpens up noticeably compared with the standard damper. Braking stability improves too – with less nose-dive under heavy braking into a corner, the front tyres keep more usable grip right when you need it. The result on track is a car that changes direction with intent instead of settling into a lean and staying there, which matters more on a 1.9-tonne AWD platform than on almost anything lighter.

About the Racing Spec coilover

Racing Spec is XYZ Racing’s dedicated circuit-use damper, and its baseline settings weren’t arrived at on a test bench alone – they come out of the company’s direct involvement in circuit racing, including WTCC competition, where damper behaviour gets validated under conditions a road car never sees. That racing-programme lineage is the point of difference between this and a fast-road spec: it’s tuned for repeated hard laps rather than a single spirited drive. For FX35/37 owners running more aggressive builds – cars closer to a genuine track weapon than a stock crossover, with factory-racing-style modifications already fitted – XYZ Racing also offers a bespoke path: supply full detail on what’s already been changed on the car and which circuit it’ll be run on, and the shock absorbers can be custom-specified around that exact build rather than sold off the shelf. It’s the same approach XYZ applies across its racing-derived range, treating each aggressively-modified car as its own engineering brief rather than a generic fitment.

Fitment for the Infiniti FX35/37 S51 4WD (Modified Rr Integrated) (2008-2013)

This kit is built specifically for the S51-chassis FX35/37, 4WD, across the 2008 to 2013 model years, using the modified rear-integrated mounting approach noted in the product name – confirm your FX is the 4WD S51 variant within that year span before ordering, as coverage does not extend to other FX chassis generations or drivetrain configurations.
