ISC Suspension S001-T N1 Coilover Kit Street and Track

The ISC Suspension N1 Coilover Kit is a full-featured, performance-oriented suspension system engineered for both street driving and weekend track use. Built entirely in-house by ISC — a company with over 12 years of motorsport heritage across Asia and Australia — the N1 delivers race-proven engineering with premium quality control and continuous R&D refinement.

Construction & Materials:

• Lightweight T6061 aluminum alloy body and adjustment locks for reduced unsprung weight
• ISC Gold or Black anodized finish resists corrosion and surface rust
• StreetSeal corrosion protectant technology for long-term durability
• Top-grade hardware throughout, including pillowball upper mounts for optimal handling precision
• Brake line and mounting brackets welded to bottom mounts for OEM-style fitment on most applications

Damper & Shock Design:

• Mono-tube single-cylinder design with high-pressure nitrogen gas for advanced driving stability
• 32-step damper adjustment — rebound and compression adjusted simultaneously via a single knob
• High-rigidity steel piston rods meeting race and sport standards
• Shafts valved according to selected spring rate; each unit shock-dyno tested for consistent, quality results
• Powder-coated and salt-spray-coated threaded shaft section for maximum street durability

Spring System:

• High-quality SAE9254 steel sports springs
• Compression-tested over 500,000 cycles with less than 5% deformation
• Available in Street Comfort, Street/Sport, or Track/Race spring rate configurations; fully custom rates available
• Bound-adjustable with separate spring locks — preload is independent from ride height so lowering does not compromise ride quality

Ride Height & Geometry:

• Full-length ride height adjustment — 3 inches or more of range on most applications
• Adjustable front camber plates included as standard on applicable vehicles
• Thrust bearing kit included at no extra charge — eliminates spring bind commonly associated with aftermarket coilovers

Certifications & Warranty:

• SO9001:2000R Certified manufacturing process
• ARTC Certified
• 5-Year Warranty — all service, rebuilds, and warranty support handled at ISC's USA facility in New Hampshire; custom orders are hand-assembled on-site

The ISC N1 coilover kit is a comprehensive suspension upgrade offering professional-grade adjustability, durable construction, and factory-backed support — making it an exceptional value for performance enthusiasts and track-day drivers alike.
