Cusco 6C1 61P CN Street Zero Coilover Kit Twin-Tube Full-Length Adjustable

The Cusco 6C1 61P CN Street Zero Coilover Kit is a premium twin-tube coilover suspension system engineered for street-focused performance. Designed with a full-length ride height adjustment system, these coilovers allow you to dial in your ideal stance without compromising shock stroke or spring preload, delivering consistent handling characteristics at any ride height.

The Street Zero series uses a newly developed twin-tube shock absorber with an internal low-compression gas charge, producing a quiet, compliant ride quality well-suited to daily driving. An innovative base valve design allows the damping to adapt across a wide range of road surfaces, providing confident control from urban streets to spirited canyon runs.

Key Features:

• Twin-tube shock absorber with internal low-compression gas for a smooth, quiet ride
• Full-length ride height adjustment — lower the vehicle without affecting shock stroke or spring preload
• Fixed damper rate tuned specifically for street use
• Rigid (hard) rear upper mount for improved steering response and suspension precision
• Nickel-chrome plated adjustment screws for long-term corrosion resistance against rust, sand, and dust
• Polymer thrust sheet on lock nuts to prevent loosening and reduce noise
• Designed with sufficient bump stroke even at lowered ride heights
• Domestic Japanese production for consistent quality and fitment accuracy

The Cusco Street Zero 6C1 61P CN is purpose-built for the Toyota GR86 (ZN8) and Subaru BRZ (ZD8) platform, offering a well-balanced suspension upgrade that improves handling dynamics and stance while remaining comfortable for everyday street use.
