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

The S51-generation FX35/37 carries close to two tonnes of 4WD crossover through corners on a factory suspension tuned for isolation rather than composure, and that mass shows up first as body roll in direction changes and dive under hard braking. The XYZ Racing Super Sport coilover, built for this Modified Rr Integrated rear set-up, gives the FX a damper you can wind stiffer for a track afternoon and back off again for the commute.

Super Sport sits below XYZ’s dedicated circuit ranges but above a simple lowering kit, aimed at FX35/37 owners who want genuine fast-road control and the occasional track day without turning a heavy 4WD platform into something that rattles your fillings on a UK B-road.

What this coilover does for your 2008-2013 Infiniti FX35/37

Fitted correctly, the 36-way damping adjustment lets you set compression and rebound with enough range to calm the FX’s pitch under hard braking, where the factory dampers let the nose dive and unsettle the rear axle. Because ride height is independently adjustable, you can drop the centre of gravity without relying on spring rate alone, which cuts body roll through direction changes more effectively on a vehicle carrying this much weight up high. The Modified Rr Integrated rear end means the rear damper reworks the factory multi-link geometry rather than fighting it, so lateral grip through the rear axle improves without the vague, wandering feel some spring-only lowering kits introduce on 4WD FX35/37s. Day to day, the softer end of the adjustment range still leaves enough compliance to keep the ride usable over speed humps and poor surfaces, rather than forcing a track-only setting on a car you also have to commute in.

About the Super Sport coilover

Super Sport is XYZ Racing’s mid-tier damper, built to take the harshness out of rough road surfaces without giving up the adjustability a heavier platform like the FX35/37 needs. The damper offers 36 clicks of adjustment, enough range to move from a comfort-biased setting for daily driving to a firmer track setting without swapping parts. Ride height adjusts independently of damping, so stance and corner weight can be set without changing how the damper responds to inputs. XYZ designed the range around cars that see both weekday driving and weekend circuit or fast-road use, rather than a dedicated race damper that would be unusable on the road. On a car the size and weight of the FX35/37, that wide adjustment window and comfort-capable base tune matter more than they would on a lighter coupe, because the damper is doing more work to control mass in every direction.

Fitment for the Infiniti FX35/37 (2008-2013)

This kit is built for the S51-generation FX35 and FX37, chassis code IN01, across the 2008 to 2013 model years in 4WD guise. It is specced for the Modified Rr Integrated rear set-up, meaning the rear damper and mounting are matched to this platform’s factory multi-link rather than a generic bolt-in. Confirm your FX is the 4WD S51 before ordering, since the rear integration is specific to this drivetrain layout.
