ISC Suspension S001-S N1 Street Sport Coilover Kit

The ISC Suspension N1 Street Sport Coilover is a fully featured, self-manufactured coilover system engineered for enthusiasts who demand improved handling on the street or weekend track. Backed by over a decade of development and real-world feedback from drift, road course, and street driving applications across Asia and Australia, the N1 represents ISC's commitment to performance, quality, and value.

All N1 coilovers are hand assembled and warranted out of ISC's New Hampshire, USA facility, and are backed by a 5-year warranty with full rebuild and service support handled domestically. The N1 is SO9001:2000R and ARTC Certified.

Key Features:

• 32-Step Damper Adjustment: Rebound and compression are adjusted simultaneously via a single 32-step knob for easy, precise tuning
• Pillowball Upper Mounts: Included standard on all N1 kits for optimal handling response and performance
• Thrust Bearing Kit: Included at no extra charge — eliminates spring bind, a common issue with aftermarket coilovers
• Adjustable Front Camber Plates: Included where vehicle suspension geometry allows (application-specific)
• Ride Height Adjustable: Full-length adjustment of 3 inches or more on most applications; preload is independent of ride height so ride quality remains consistent even at lower settings
• Monotube Single Cylinder Design: Larger cylinder and piston for improved driving stability; high-pressure nitrogen charged for consistent damping performance
• High Rigidity Steel Piston Rods: Valved to match your chosen spring rate; each unit is Shock Dyno tested for quality and consistency
• SAE9254 Sports Springs: High-quality steel springs dyno tested over 500,000 compression cycles with less than 5% deformation
• T6061 Aluminum Construction: Lightweight anodized aluminum alloy used for adjustment locks and brackets — available in ISC Gold or Black anodized finish to resist corrosion and surface rust
• StreetSeal Corrosion Protection: Powder-coated and salt-spray-coated threaded shaft sections for enhanced durability in harsh weather conditions
• OEM-Style Bottom Mounts: Brake lines and mounting brackets are welded onto bottom mounts on most applications for clean, factory-style fitment
• Fully Custom Spring Rates & Valving Available: Choose from Street Comfort, Street/Sport, or Track/Race configurations; fully custom spring rates available upon request

The ISC N1 coilover kit delivers a rare combination of professional-grade engineering, in-house quality control, and enthusiast-level customization — all backed by domestic warranty support and one of the most comprehensive standard feature sets in its class.
