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

The BNR34 is one of the few cars from its era that genuinely warranted its own chassis designation – the multi-link rear suspension with its fork-type lower arm geometry is specific to the GT-R, separate from the standard ER34 and NR34 Skyline variants, and the ATTESA E-TS all-wheel-drive system running through it still holds up against far newer hardware. Factory dampers, however, were specced to 1999 tolerances; twenty-five years of road use, variable-quality replacement parts, and perhaps the occasional circuit session have typically left the BNR34’s suspension a long way below its original capability.

The XYZ Racing Street Advanced coilover kit addresses that directly, built for the fork-mount rear geometry of the BNR34 and offering 720 ways of damping adjustment. The Street Advanced targets road use and track-day sessions in equal measure, which on a car like the BNR34 – often driven to a circuit rather than trailered – is a practical engineering decision as much as anything else.

What this coilover does for your 1999-2002 Nissan Skyline R34 BNR34 4WD

The 720-step damping range means the gap between motorway comfort and circuit stiffness is resolved at the adjuster, not by swapping components. On the BNR34 this matters specifically because the ATTESA E-TS system distributes torque partly based on what the rear axle is doing; coilovers that let you tune rear damping with genuine resolution give you meaningful influence over the car’s traction behaviour in a way that worn or generic units simply cannot. Thread-adjustable ride height lets you correct stance without sacrificing coilover travel, relevant on a car that was already sitting relatively low from the factory. Spring rates are matched to the BNR34’s platform rather than a lighter front-wheel-drive application, preserving the suspension geometry the multi-link setup was engineered around.

About the Street Advanced coilover

Developed over years by XYZ Racing’s professional engineering team and validated through competition at circuits worldwide, the Street Advanced is the brand’s most widely chosen coilover product. That racing programme history informs the specification: the 720-way damping adjustment range represents genuine valve-resolution across those positions, not a headline number that collapses in practice to three or four usable settings. It is built specifically to cover normal road driving and track-day use within the same product, acknowledging that most BNR34 owners want a coilover that performs on public roads as readily as on circuit – rather than a setup that excels at one and punishes every speed bump on the road home. The depth of development behind it – years of professional engineering tested in competition worldwide – is what separates this from a generic replacement damper that simply restores stock behaviour.

Fitment for the Nissan Skyline R34 BNR34 (1999-2002)

This kit is listed under chassis code NI41 and covers the BNR34 GT-R produced from 1999 to 2002. The rear coilover mount is configured specifically for the fork-type lower arm geometry unique to the BNR34, making it incompatible with non-GT-R R34 variants – the ER34 and NR34 use a different rear suspension architecture entirely. Confirm your BNR34 chassis plate before ordering if there is any doubt about which R34 variant you have.
