Product Details

These APEXi N1 Evolution coilovers fit the 1989-1991 Nissan 180SX (S13). The N1 Evolution Damper uses a dedicated 46mm resin-bonded piston developed for this system, with spring rates and damping tuned for handling and body control on the street.

The N1 Evolution Damper prioritizes damping control over raw stiffness, delivering confident handling on winding roads, stable control during spirited driving, and an excellent balance between comfort and performance. Available in Sports Standard specification for enthusiast street driving, or as a Special Order Setting with fully custom-built damping and spring rates tailored to specific motorsport disciplines, including circuit racing, drift, gymkhana, rally, and drag.

Every N1 Evolution kit features monotube construction for consistent fade-free performance, a threaded-body design for precise ride height adjustment, and high-performance upper mounts for improved steering response. Front camber adjustment plates are included for precise alignment tuning. Bolt-on installation with no modifications required. APEXi's factory overhaul and rebuild services keep your dampers performing at their peak for years to come.
