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

The RZ34 Fairlady Z carries a torquey twin-turbo VR30 up front and a rear subframe geometry that Nissan revised specifically to handle that power on the way out of a corner. Stock dampers are tuned for a broad customer base, not for someone loading the rear axle hard on a second-gear exit. Circuit Master exists for that exact scenario: repeated, sustained laps where the chassis needs to stay settled corner after corner rather than just surviving one hot session.

This is the range built for drivers who actually book track days in their RZ34, not the ones who want a lower stance for the car park. With the rear integrated per the modified Rr Integrated fitment, the kit works with the Z’s specific rear geometry rather than fighting it, keeping the back axle planted through direction changes instead of skating wide.

What this coilover does for your 2022-2026 Nissan FAIRLADY Z RZ34 (modified Rr Integrated)

Circuit Master’s 3-way adjustment lets you separate low-speed compression, high-speed compression and rebound instead of chasing one dial for every condition – useful on a car that swings between a bumpy access road and a smooth circuit surface in the same day. Because the rear damper is matched to the RZ34’s modified Rr Integrated mounting point, load transfer under trail-braking goes through a rear axle that’s actually set up for it, rather than through a generic bracket adaptation. Firming the front end reduces the nose-dive that the VR30’s weight otherwise induces under braking, sharpening turn-in without the car pitching forward first. On a car this quick out of a corner, matched damping front to rear keeps the rear tyres loaded evenly as power comes down, which is what actually lets you get on the throttle earlier rather than waiting for the chassis to settle.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s range, built for circuit driving where the same corner gets hit dozens of times in a session rather than once. XYZ says the damper has been run and validated by its own racing teams on circuits internationally, and the headline figure is 9,720 individual damping combinations across the 3 adjustment knobs – enough range to move from a soft trailing-throttle setup to a stiff, flat circuit tune on the same shock body. The knobs use a small-orifice oil-passage design to deliver that granularity; XYZ notes this can produce a minor oil-flow noise over sharp bumps, which is a normal characteristic of the fine-adjustment design rather than a fault, and one that matters less on a smooth circuit surface than it would on a broken B-road. The construction and adjustment range are aimed squarely at repeat-lap consistency rather than a single quick blast.

Fitment for the Nissan FAIRLADY Z RZ34 (modified Rr Integrated) (2022-2026)

Built specifically for the RZ34-generation Fairlady Z, chassis code NI72, covering the 2022 to 2026 model years. This kit uses the modified Rr Integrated rear configuration, so confirm your car matches that rear-end spec before ordering rather than assuming a standard rear mounting will apply.
