XYZ Racing Street Advanced Coilovers — Infiniti QX70 (S51) 4WD 2013-2017

The S51 QX70 carries close to two tonnes high off the deck, and the factory dampers were tuned to disguise that mass rather than master it. Lean on the standard setup through a quick direction change and the body takes a beat to settle, the nose dips under braking, and the 4WD platform feels heavier than its Nissan FM underpinnings suggest. The XYZ Racing Street Advanced coilover for the Infiniti QX70 (S51) 4WD goes at that float directly.

This is the road-biased kit in the XYZ range, built for owners who want a flatter, more deliberate QX70 without giving up the ride quality that makes it a usable daily. It lowers the centre of gravity, tightens body control, and gives you a ride-height and damping window to set the car up the way you actually drive it.

What this coilover does for your 2013-2017 Infiniti QX70 (S51) 4WD

Drop the S51 onto a set of Street Advanced coilovers and the first thing you notice is how much sooner the body settles after a bump or a lane change. The 720-way damping adjustment lets you run the QX70 soft enough for motorway miles, then firm it up when you want the crossover to hold a line on a B-road or a track day. Lowering the ride height shrinks the wheel-arch gap that leaves the standard car looking like it is on stilts, and it pulls the centre of gravity down so the SUV rolls less and turns in with more intent. Braking feels more composed too, with less forward pitch loading the front axle. Because height and damping adjust independently, you can corner-balance the car around the diesel or petrol nose weight instead of accepting a single factory setting.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most popular damper and the one its engineers have spent years refining through competitive use worldwide. The headline figure is 720 ways of damping adjustment, a combined bump-and-rebound circuit that moves the car from compliant cruiser to tied-down corner tool through one easily reached knob per strut. XYZ pitches it squarely between everyday road use and the occasional track day, which is exactly the brief for a fast-road SUV like the QX70. The valving is developed and tested on track before it reaches the street, so it is built to take repeated hard inputs rather than fade after a handful of hot laps. For an S51 owner, this is the kit that prioritises liveable comfort and adjustability over the harder, track-first focus of the firmer XYZ ranges.
