Cusco 564 64S CN Sport S Coilover Kit

The Cusco 564 64S CN Sport S Coilover Kit is a premium suspension system engineered for enthusiasts who demand track-ready performance without sacrificing street comfort. Developed by Cusco Japan, a division of Carrosser Co. Ltd., this coilover system brings decades of motorsports expertise from rallying, track racing, and gymkhana directly to your build.

Advanced Monotube Construction:

The Sport S features monotube shock absorber design with a larger diameter piston for enhanced rigidity and increased fluid chamber volume. This configuration allows for a higher range of piston speeds and delivers finer damper control at all stroke speeds, resulting in superior handling response and consistency.

Key Features:

• 24-step adjustable damping for precise tuning on both front and rear
• Full-length height adjustment without affecting spring preload or damper stroke
• Front spring rates: 8kg/mm standard (optional 6, 7, 9, 10, 11, or 12 kg/mm available)
• Rear spring rates: 5kg/mm standard (optional 6, 7, 8, 9, or 10 kg/mm available)
• Reinforced rubber rear upper mounts for increased ride comfort and reduced noise
• Height adjustment range: Front -60 to 0mm / Rear -70 to 0mm
• Precision-wound blue springs using advanced anti-sagging metallurgy with shot-peening treatment

Street-Tuned Performance:

The Sport S was developed following Cusco's Sport R racing specifications but with damping force, spring rates, and stroke specifically calibrated for street use. This makes it the ideal choice for drivers who enjoy spirited canyon runs or occasional track days while maintaining a comfortable daily driving experience. The reinforced rubber rear upper mounts enhance compliance over rough surfaces while minimizing cabin noise compared to full pillowball mount systems.

Backed by Cusco's reputation for quality manufacturing and rigorous testing in professional motorsports, the 564 64S CN delivers the perfect balance of adjustability, performance, and comfort for the demanding automotive enthusiast.
