XYZ Racing Super Sport Coilovers — Infiniti QX70 (S51) 4WD 2013-2017

The S51 QX70 carries serious mass over its front axle – a 3.7-litre VQ37VHR sat ahead of a permanent 4WD driveline, wrapped in a body that was always more grand tourer than crossover. The factory dampers were tuned for refinement first, which is why these cars roll progressively through quick direction changes and squat noticeably under throttle out of slower corners. The XYZ Racing Super Sport coilover for the Infiniti QX70 (S51) 4WD addresses that directly.

This is the right coilover for an owner who wants the QX70 to feel like the sporting SUV its styling promised – sharper turn-in, controlled body movement, adjustable ride height to clean up the arch gaps – without giving up daily usability. Fast-road biased, with enough range to handle the occasional weekend track outing.

What this coilover does for your 2013-2017 Infiniti QX70

Drop the ride height to taste and the QX70’s stance tightens up immediately – the gap above each 20-inch wheel closes, and the centre of gravity drops with it. On the move, body roll is reined in through faster sweepers, and the nose stops pitching under hard braking into roundabouts and slip roads. The 36-way damping adjustment is the practical bit: wind the dampers softer for motorway runs and broken urban tarmac, then firm them up for a B-road blast or a track day at Donington. Turn-in becomes more deliberate, and the rear axle stays planted when you ask the 4WD system to put power down out of a corner. Even ride compliance over expansion joints and patched surfaces is preserved at sensible settings – the Super Sport is not a stiff-for-stiff’s-sake setup.

About the Super Sport coilover

The Super Sport is engineered to eliminate the harshness that usually arrives when you lower a heavy 4WD platform. Ride-height adjustment is independent of damper preload, so you can sit the QX70 where you want it without compromising travel. The 36-way damping adjustment is accessed via a knob on each strut, giving genuinely usable compression and rebound control across the full range – one setting for the daily commute, a second for a Sunday morning, a third for a circuit session. Construction is built around fast-road durability, with the breadth to absorb broken UK tarmac while still tightening up when called on. It is positioned squarely as a high-performance damper that suits weekend race work and daily use in equal measure – the right brief for a QX70 that needs to behave on a wet M25 commute and a dry Cadwell trackday in the same week.

Fitment for the Infiniti QX70 (2013-2017)

Built specifically for the S51 chassis QX70 in 4WD specification, covering the 2013 to 2017 model years. This is the post-FX facelift QX70 wearing Infiniti badging, with the permanent all-wheel-drive driveline rather than any rear-wheel-drive variant.
