XYZ Racing Racing Spec Coilovers — Nissan 370 Z Z34 Rear FORK (Modified Rear Integrated) 2009-2022

The 370Z’s VQ37VHR sits behind the front axle but still loads a fair chunk of weight onto the nose under trail-braking, and on the standard dampers that shows up as a soft, delayed transition into corner exit. Racing Spec coilovers replace that with a set-up derived directly from XYZ Racing’s WTCC touring car programme, where the damping curves were shaped for repeated hot laps rather than a single fast one.

On a Z34 built for serious track and time-attack days, that means the rear FORK-modified, RR-integrated set-up keeps the rear axle locating points consistent as load transfers under braking and power-down, instead of letting geometry drift lap after five. This is a circuit-first spec, not a fast-road compromise.

What this coilover does for your 2009-2022 Nissan 370 Z

Fitted to the 370Z, the Racing Spec kit tightens body control through direction changes without adding the harshness that generic stiff springs bring to a road car – because the damping was tuned to match the spring rate, not bolted on afterwards. Corner-entry response sharpens noticeably: the nose stops diving into slow corners, so trail-braking becomes a tool rather than a guess. Under power out of hairpins, the rear FORK/RR-integrated hardware controls squat so the VQ37’s torque goes into forward drive rather than axle movement. Ride height is adjustable independently of spring preload, so you can set the Z34’s stance and corner weights without touching the damping you’ve settled on for a given circuit.

About the Racing Spec coilover

XYZ Racing built the Racing Spec range specifically for track racing, with its damping curves pulled from real WTCC entries rather than generic bench testing. Where a car has already picked up aggressive supporting modifications – wider tyres, aero, a built engine – XYZ can produce a custom-valved shock absorber rather than a shelf spec, using details the owner supplies about the rest of the build and the circuit they intend to run. For most 370Z owners the standard Racing Spec calibration covers it: a monotube-style track damper matched to a spring rate chosen for sustained circuit loads rather than a single session. It’s built for cars that go back out for another run, not just a track-day photo.

Fitment for the Nissan 370 Z (2009-2022)

Racing Spec coilovers under SKU XYZ-COIL-NI04-RS are built for the Nissan 370Z Z34, covering the 2009-2022 production run, with rear-fork modification and RR-integrated rear damper mounting specific to this chassis. Confirm your Z34’s rear suspension carries the FORK/RR-integrated hardware referenced here before ordering, as this variant is distinct from a standard rear set-up.
