Infiniti QX70 (S51) 4WD 2013-2017 — Coilovers

The Infiniti QX70’s two-tonne kerb weight and tall, cab-rearward stance are the two things any suspension change has to answer for. Built on the front-midship architecture that underpins Nissan’s Z cars but wrapped in a luxury-crossover body, the S51 wants far more body control than its soft factory damping ever offers. The XYZ Racing coilover range for the 2013-2017 QX70 4WD exists to put that mass back under control.

This is a family of seven setups rather than a single kit, spanning fast-road comfort through to dedicated circuit and rally specs. Every option shares ride-height and damping adjustment, so you can drop the QX70’s ride height to sharpen its look and lower its centre of gravity, then set the damper firmness to match how you actually use the car.

What this coilover range does for your 2013-2017 Infiniti QX70

Lowering a heavy crossover like the QX70 pays back twice: the centre of gravity drops and the body stops leaning so hard mid-corner, which is exactly what a near-2,100kg SUV needs. Adjustable damping lets you firm up the soft initial body movement the factory dampers allow, so the nose settles faster under braking and the rear stops wallowing over crests. Height adjustment closes the large factory arch gap and tightens the stance without spacers or guesswork. On the 4WD drivetrain, better-controlled weight transfer helps the front axle find grip earlier on turn-in, taking the edge off the understeer a nose-heavy V6 or V8 layout builds in. The net effect is a QX70 that changes direction like it carries less weight than it does.

About the coilover range

XYZ Racing builds this range as seven distinct specifications for the same S51 chassis, each tuned around a different way of driving the car. Super Sport sits at the fast-road end, keeping daily usability while adding a real step in body control. Top Sport and Circuit Master move towards track work, with firmer rates aimed at sustained cornering loads, and Racing Spec is the hardest circuit option in the family. Tarmac Rally and Pro Rally are set up for the higher-amplitude, rougher-surface work that stage and tarmac events demand, while Drift Spec is geared towards angle, steering response and lock. All seven are coilover kits with adjustable ride height and damping, so the broad character is chosen by spec and the fine detail is set by you on the car. Picking the right one comes down to how often the QX70 sees a circuit, a stage or just a quick B-road.

Fitment for the Infiniti QX70 (S51) 4WD (2013-2017)

Every kit in this range is built for the Infiniti QX70 on the S51 chassis with four-wheel drive, covering the 2013 to 2017 model years. Confirm your car carries the S51 chassis code and the 4WD drivetrain before ordering, as fitment is specific to that combination. The differences between specs sit in the damping and spring tune, not the mounting hardware.
