XYZ Racing Street Advanced Coilovers — Nissan SILVIA S13 1989-1994

The S13 Silvia arrived in 1989 with suspension calibrated for the Japanese domestic market – compliant enough for motorway cruising, deliberately soft in a way that felt sophisticated at the time but works against the car’s natural rear-wheel-drive balance on any road with corners. Nissan’s multi-link rear is capable geometry, but the stock spring rates leave it compressing into its travel earlier than it should under load.

The Street Advanced coilover replaces the entire spring-and-damper assembly with a height-adjustable setup, giving S13 owners the ability to run a sensible ride height and adjust the car’s responses to match the way they actually use it.

What this coilover does for your 1989-1994 Nissan SILVIA S13

Lower the S13 on the Street Advanced and the improvement in body control through fast corners is immediate. Soft OEM spring rates allow the outer wheel to compress quickly, loading the multi-link rear unevenly before the car has settled – felt as a slight hesitation or vagueness just after turn-in. Firmer rates, combined with the coilover’s 720-way damping adjustment, reduce that compression without transmitting road noise that makes longer journeys unpleasant. The centre of gravity drop from a more aggressive ride height also reduces lateral weight transfer on the S13’s relatively narrow track, making the car feel more planted mid-corner. At softer damping settings the coilover handles potholed A-roads without the jarring that stiffer track-focused units produce; harder settings are there when the road clears.

About the Street Advanced coilover

The Street Advanced is XYZ’s most widely adopted coilover – a line developed over several years by the company’s engineering team and validated against racing events worldwide before production. It covers the middle ground between a comfort-oriented road suspension and a full track setup, making it the practical choice for S13 owners whose car sees both. The 720-way damping adjustment is the defining feature: 720 discrete positions provide enough range to tune for motorway driving at one end and spirited B-road work at the other, without swapping parts. Construction is aimed at enthusiast road use and occasional circuit work rather than competitive motorsport, which keeps ride quality in a range that daily use doesn’t make punishing.
