Which variants this covers
The S13 and S14 are both listed, and several S15 Silvia parts are cross-compatible where the mounting and stroke match — the listings note this individually rather than as a blanket rule. All are rear-wheel-drive coupés with independent suspension at both ends. Many surviving cars have been modified already, so what is bolted to yours matters as much as which model it is.
Choosing between the ranges
This is a coilover page first and foremost, and the reason is drift and track use rather than ordinary motoring. Flex Z is the most stocked and the best-balanced choice for a car that still sees the road, offering full-length height adjustment alongside sixteen damping settings. Street Basis Z is the cheapest way into adjustable height and Street Advance Z sits between the two. Mono Sport is the one to choose for competition use, where its stiffness is the point rather than a drawback. S.Tech springs suit a largely original car being gently lowered, and the single Bilstein B6 listing covers standard-height damping for an unmodified example.
What to check before ordering
Replace per axle and have the alignment and corner weights set together afterwards; on a car used sideways the settings matter more than the parts. The specific issue with these is history: three decades of modification mean the subframes, arms and mounts are frequently non-standard, so confirm what is actually fitted before ordering anything that bolts to it.
Common questions for this chassis
Do S15 parts fit an S14? Sometimes. The listings flag compatibility case by case rather than generally.
Which coilover for a drift build? Mono Sport. Flex Z if the car is still driven on the road.
Is there much Bilstein for these? One B6 listing — the coverage here is overwhelmingly Tein.
