XYZ Racing Super Sport Coilovers — Nissan SILVIA S15 1998-2000

The S15 Silvia’s MacPherson strut front and independent multilink rear represented Nissan’s most refined iteration of the S-chassis formula – but the factory damper tune was calibrated for the Japanese domestic market’s variable road surfaces, not the sustained pace that the SR20DET encourages. The Super Sport coilover addresses the gap between what the chassis is capable of and what the standard suspension actually asks of it.

XYZ Racing positions the Super Sport as its fast-road and weekend track specification: a full coilover conversion with 36-way damping adjustment and adjustable ride height, built for S15 owners who want a single setup that covers a Tuesday commute and a club track day without requiring separate hardware for each.

What this coilover does for your 1998-2000 Nissan SILVIA S15

The S15’s rear multilink geometry is notably sensitive to damper calibration – it’s part of what made the S-chassis a staple of UK club circuit work and time attack, because small changes at the rear produce predictable, measurable results. With 36-way adjustment, the Super Sport works across a meaningful spread: firm the rear for a session at Brands Hatch or Cadwell and back it off for the drive home. Adjustable ride height lets you correct the standard stance or lower the centre of gravity for circuit use without stranding the car on UK road camber. The construction eliminates the secondary vibration that the standard Japanese-spec dampers transmit on rough surfaces – useful on UK B-roads, where the S15’s relatively stiff bodyshell transfers surface texture directly into the cabin.

About the Super Sport coilover

XYZ Racing’s Super Sport is built for dual-use ownership – not a stripped race unit, but a damper specification with the road-and-track split clearly in mind. The headline feature is 36-way damping adjustment, which provides a working range wide enough to run a genuinely soft daily setting at one end and a firm weekend setting at the other without running out of travel at either extreme. Ride height is adjustable via the spring perch, allowing a meaningful drop for circuit work or a conservative stance for regular road use. The damper construction targets the discomfort and secondary vibration that stock bumpstops and factory dampers pass through on rough or broken surfaces. XYZ rates the Super Sport for both weekend competition use and regular daily driving.
