XYZ Racing Top Sport Coilovers — Nissan FAIRLADY Z RZ34 (Modified Rear Integrated) 2022-2026

For a driver splitting daily commutes with the occasional track-day entry in the twin-turbo RZ34, ride quality and body control usually pull in opposite directions. Stiffen the rear too far and the multi-link geometry starts fighting mid-corner bumps instead of absorbing them. The Fairlady Z carries real weight over the front axle once the VR30DDTT and its intercooling are accounted for, and that mass has to be managed through trail-braking without turning every expansion joint into a jolt through the cabin.

XYZ Racing’s Top Sport coilover is built for exactly that split use: enough damping range and spring rate to keep the RZ34 flat under load on a track day, without the ride collapsing into harshness on the drive home.

What this coilover does for your 2022-2026 Nissan Fairlady Z RZ34

Set up correctly, the Top Sport kit raises damping by roughly 30-50% over a street-tuned coilover, or adds around 2kg/mm to the spring rate depending on which axis you prioritise – either route cuts the body roll and squat a factory-spec RZ34 shows once cornering loads climb. That extra control matters most under braking into a corner, where the front end’s mass wants to keep travelling after the wheel has turned in; a firmer front rate holds the contact patch flat and lets the tyre do the work instead of the sidewall. Over broken tarmac and expansion joints, the kit is tuned to absorb the initial impact rather than pass it straight through, which keeps the rear axle loaded and traction consistent instead of skipping over bumps mid-corner.

About the Top Sport coilover

The Top Sport sits above XYZ Racing’s street-focused ranges because it trades some everyday plushness for control: damping is raised by 30-50% and spring rates by around 2kg/mm compared with a street setting, absorbing the shock of rough pavement and larger compressions before it reaches the chassis rather than letting the body kick back afterwards. That construction is aimed at suppressing body movement under load and keeping the tyre’s contact patch working, which is where the stability comes from rather than spring rate alone. XYZ Racing carries these settings over directly from its own Top Sport programme rather than deriving them on a rig, and the result is a kit built for track-day sessions and aggressive road driving rather than comfort-first commuting. On the RZ34’s chassis specifically, that means a setup that can be pushed hard on a circuit outing without needing a full respring for the road journey there and back.

Fitment for the Nissan Fairlady Z RZ34 (Modified Rr Integrated) (2022-2026)

This kit is specced for the Nissan Fairlady Z RZ34 across the 2022-2026 model years, built around the modified rear-integrated suspension mounting used on this chassis (chassis code NI72). Confirm your build year falls inside that range before ordering, since running changes across the RZ34’s production can affect rear mount compatibility.
