XYZ Racing Street Advanced Coilovers — Nissan SKYLINE R34 (Rear FORK) 1999-2002

The R34 Skyline’s rear-fork multi-link suspension is one reason this chassis still attracts serious owners in 2026 – it is a genuinely sophisticated rear end, but the stock damping calibration leaves a significant amount of handling potential untapped. The XYZ Racing Street Advanced coilover for the Nissan Skyline R34 (Rr Fork) addresses that gap directly, pairing an adjustable ride height with 720 damping positions covering everything from a loaded motorway run to a full circuit day.

Running a 24-year-old R34 on modern road surfaces means asking the suspension to cope with bumps and joints the original engineers did not design around, and the Street Advanced’s adjustment range gives you the tools to compensate. This is a road-and-track coilover in the literal sense: the calibration sits in the overlap between both demands rather than compromising hard in one direction.

What this coilover does for your 1999-2002 Nissan SKYLINE R34 (Rr FORK)

The fork-type rear lower arm configuration on these R34 variants responds sharply to increased spring rates – firmer rates reduce the squat under hard acceleration and tighten the car’s responses to trailing throttle at corner entry. With 720 damping adjustment positions available, the transition between road-biased and circuit-biased settings is incremental rather than binary: add rebound stiffness before a track session, reduce it before the drive home. Ride height is adjustable independently from spring preload, so lowering the R34 to reduce centre-of-gravity height does not force a penalty on rear wheel travel over rough surfaces. For a chassis this age that owners are still running seriously, that degree of control over both axles earns its cost.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most popular product – a specification developed over years by their in-house engineering team and validated across professional race events worldwide. The key figure is 720 damping adjustment positions: the steps are fine enough that changes between settings register as real differences in car behaviour rather than theoretical adjustments on paper. XYZ designed the Street Advanced specifically for the overlap between road driving and circuit use, so the internal valving tolerates the varied demands of a car that does motorway miles and track gates in the same week. The result is a coilover that does not force a binary choice between road compliance and circuit capability – both fall within the same hardware and the same setup, without swapping components between uses. For Nissan Skyline owners who drive year-round and occasionally take the car to a circuit, the design intent maps cleanly onto how these cars are actually used.

Fitment for the Nissan SKYLINE R34 (Rr FORK) (1999-2002)

These coilovers are built for the NI43 chassis code, covering Nissan Skyline R34 variants fitted with the rear fork suspension configuration across the 1999-2002 production run. The Rr Fork designation refers to the specific rear lower-arm geometry fitted to applicable R34 models; if your car carries this configuration, these are the correct units. Confirm your variant’s rear suspension type before ordering if there is any uncertainty about which rear setup your R34 has.
