Product Details
These HKS Hipermax S S13 Silvia coilovers fit the 1988-1993 Nissan Silvia (S13/PS13).
HKS builds these S13 Silvia coilovers with 7 kgf/mm front and 5 kgf/mm rear springs and 30-level damping adjustment. The Silvia is a Japan-market (JDM) car.
This is the redesigned Hipermax S, built around HKS's Flat Ride Concept: the chassis stays level through mid-corner load transfer and stays composed over broken pavement. Every 80330-series kit is built in Japan and stays fully rebuildable through HKS.
