XYZ Racing Circuit Master Coilovers — Nissan SKYLINE R34 BNR34 4WD (Rear FORK) 1999-2002

The BNR34’s fork-type rear lower arm is unique within the R34 Skyline family – and it is the first thing to understand when choosing a coilover for this car. Standard fitments that work on the RB25 straight-six variants won’t seat correctly on the GT-R’s rear suspension geometry, which is why the XYZ Racing Circuit Master for the Nissan Skyline R34 BNR34 is built to a specific bracket specification for that fork configuration.

Circuit Master is XYZ Racing’s competition coilover line, positioned explicitly for sustained lap-time work rather than road use. The ATTESA E-TS Pro AWD system continuously redistributes torque against grip levels, which means the suspension loads on a BNR34 through a complete circuit lap are rarely static. That dynamic demands a damper with genuine adjustment resolution – not a fixed-rate compromise.

What this coilover does for your 1999-2002 Nissan SKYLINE R34 BNR34 4WD (Rr FORK)

With 9,720 distinct adjustment combinations across three control knobs, the Circuit Master gives BNR34 owners the granularity to work around each end of the car’s behaviour independently. Reducing ride height lowers the GT-R’s centre of gravity, progressively addressing the understeer bias that persists even with 4WD torque distribution – particularly on fast, flowing circuits where corner entry speed exposes chassis balance rather than masking it. The three-knob architecture means damping characteristics can be calibrated to a specific circuit profile without returning to a fixed baseline.

About the Circuit Master

XYZ Racing positions the Circuit Master at the top of their competition damper range, validated through their own racing teams on circuits worldwide. The three-knob adjustment system generates 9,720 possible setup combinations, placing it in the same specification tier as the brand’s Racing Spec, Drift Spec, and Tarmac Rally variants – all of which share the same competition-grade development pedigree. Construction incorporates a small-port oil passage that governs damper response through abrupt, large-amplitude bump inputs. A consequence of this design is a faint hydraulic noise when the coilover encounters a sudden sharp compression – oil moving through the restricted passage under rapid loading. On smooth race circuit surfaces this is functionally irrelevant; the design prioritises circuit consistency over kerb-stone comfort. The 1999-2002 Nissan Skyline R34 BNR34 Circuit Master coilover is not a road compromise – it is a dedicated circuit tool.

Fitment for the Nissan SKYLINE R34 BNR34 4WD (Rr FORK) (1999-2002)

This kit is designed for the BNR34 GT-R variant of the R34 Skyline – internal chassis code NI41 – covering the 1999 to 2002 production run. The rear bracket is specific to the fork-type rear lower arm used on the 4WD GT-R and is not interchangeable with standard R34 variants using a different rear lower arm configuration. Confirm your build date and rear suspension specification before ordering.
