ISC Suspension S006-T N1 Coilover Kit Street and Track

The ISC Suspension N1 Coilover Kit is a fully-featured, performance suspension system engineered for street driving and weekend track use. Built in-house by ISC — a brand with over 12 years of experience serving drift, road course, and street performance communities across Asia, Australia, and the USA — the N1 represents decades of real-world feedback and continuous development. All warranty service, rebuilds, and custom coilover assembly are handled at ISC's New Hampshire, USA facility.

Key Features:

• 32-Step Damper Adjustment: Rebound and compression are adjusted simultaneously via a 32-step single-knob system for easy, precise tuning
• Pillowball Upper Mounts: Included as standard on all N1 kits for optimal suspension geometry and response
• Thrust Bearing Kit Included: Eliminates spring bind — a common issue with aftermarket coilovers — at no additional charge
• Front Camber Plates: Adjustable camber plates included on applicable fitments (vehicle-specific; confirm via application guide)
• Ride Height Adjustment: Full-length threaded body allows 3 or more inches of adjustment on most applications; preload is independent of ride height for consistent ride quality at any height setting
• Mono-Tube Single Cylinder Design: Larger cylinder and piston for enhanced driving stability; high-pressure nitrogen charged
• High Rigidity Steel Piston Rods: Valved to match your chosen spring rate; each unit is dyno-tested for quality and consistency
• Sports Springs — SAE9254 Steel: Dyno-tested over 500,000 compression cycles with less than 5% deformation
• T6061 Aluminum Construction: Used throughout adjustment locks and brackets for lightweight strength; ISC Gold or Black anodized finish resists corrosion and surface rust
• StreetSeal Corrosion Protection: Threaded shaft sections are powder-coated and salt-spray coated for maximum durability in harsh weather conditions
• OEM-Style Lower Mounts: Brake lines and mounting brackets are welded onto bottom mounts on most applications for clean, factory-style installation
