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

The R34 Skyline arrived in 1999 carrying genuine circuit capability alongside the GT-R mythology – the BNR34’s multi-link rear suspension was among the most sophisticated production layouts of its era, and that sophistication only translates on track if the dampers can keep pace with the geometry’s full range of motion. The fork-type rear lower mount, which this kit addresses specifically, is the pivot point around which the R34’s rear axle loads and unloads under braking and through high-speed direction changes.

The XYZ Racing Racing Spec coilovers for the Nissan Skyline R34 (Rr Fork, 1999-2002) are not a road suspension dressed for occasional circuit use. Settings have been developed through direct participation in racing events – the spec reflects what demanding competition chassis actually do under load, not what they do on a test loop.

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

The factory R34 dampers were calibrated for a blend of GT road refinement and periodic circuit work – not the sustained, high-load damper cycles that time-attack or sprint events generate. The multi-link rear geometry, the same layout that gave the GT-R its progressive on-limit character, is sensitive to damper quality in both directions: rates too soft under heavy braking into slow corners allow the rear to pitch forward unpredictably, while rates set for track work feed through into front-axle behaviour under trail braking. For GT-R (BNR34) variants running ATTESA E-TS, rear damper consistency is part of the AWD system’s ability to function as designed. The Racing Spec is calibrated for class-level track use, not merely to lower ride height.

About the Racing Spec coilover

The Racing Spec is XYZ Racing’s competition-grade coilover, and what distinguishes it from their road-oriented ranges is where its settings come from: development has taken place through direct participation in events including WTCC, not road-car compromise calibration. The damper targets track and time-attack use across the full spectrum – from a modified road car running sprint days through to A-class competition vehicles. Where the Racing Spec separates itself from most off-the-shelf competition coilovers is through a custom-specification programme: if your R34 carries substantial mechanical changes – forced induction upgrades, significant weight reduction, aero – you supply details of the build and the circuit you intend to run, and XYZ Racing will engineer a custom damper calibration for that specific car. For the R34, where the gap between a lightly modified 25GT-t and a fully built BNR34 running north of 500bhp is enormous, this is a meaningful option rather than a marketing footnote.

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

This kit is built for the Nissan Skyline R34 with the rear fork lower mount configuration, chassis code NI43, covering the 1999 to 2002 production run. The Rr Fork designation refers specifically to the rear lower shock mount type – confirm your car’s rear mounting arrangement before ordering, as the R34 range includes variants with differing rear mount configurations. Full fitment confirmation is in the vehicle configurator below.
