XYZ Racing Top Sport Coilovers — Nissan SKYLINE R34 BNR34 4WD (Rear EYE) 1999-2002

The ATTESA E-TS Pro system fitted to the BNR34 is biased towards rear-wheel drive under normal conditions, distributing torque forwards only when the rear axle loses grip – a characteristic that rewards a chassis calibrated for consistent rear-axle traction above all else. XYZ Racing’s Top Sport coilover for the 1999-2002 Skyline R34 BNR34 4WD is set up around exactly that demand, with spring and damping rates drawn from track day development rather than comfort-biased road testing.

The Top Sport occupies the crossover point between daily usability and circuit intent. For the BNR34 owner running the car on road and circuit in the same week, it avoids the ride-quality penalty of full race damping while still delivering the body control the chassis needs to stay balanced through the kind of sustained corner loads the RB26 makes possible.

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

Running damping 30-50% above the street baseline keeps pitch and body roll contained through the BNR34’s multilink rear suspension, reducing the wheel-load variation that can unsettle the ATTESA torque-split under mid-corner trail braking. Stepping up the spring rate by 2kg/mm cuts dive under hard braking and squat on corner exit, giving the AWD platform a more stable base to work from. The result is more consistent tyre contact through bump events – the tread stays loaded across surface irregularities rather than skimming under compression. On the patchy, often-cambered surfaces of UK club circuits, that contact consistency matters most in the moments when the ATTESA system is working hardest.

About the Top Sport coilover

XYZ Racing’s Top Sport sits at the circuit-oriented end of the street-capable range, with calibration drawn from XYZ Racing’s own track day development work rather than extrapolated from comfort-biased road data. The specification allows a damping increase of 30-50% above street setting, or a spring rate stepped up by 2kg/mm – or a combination of both – to match track surface character and driver preference. Chassis shock suppression is a core part of the design brief: the construction is engineered to absorb the impact of large surface irregularities and keep the body platform stable rather than allowing the shell to follow every bump. A stable body keeps more of the tyre contact patch loaded, which is where the traction benefit comes from. The overall aim, drawn from XYZ Racing’s race programme, is vehicle stability that supports aggressive driving without removing the compliance the car needs for road use.
