Flex Z Full Length Adjustable Coil-Over System

It includes pillow ball upper mounts that provide a more direct connection to the road, significantly improving handling feel. The twin-tube shock absorber structure is adopted for its proven reliability, durability, and cost-effectiveness, making high performance accessible. This coilover system features a full-length adjustment function, allowing for independent adjustment of ride height and spring preload via an adjustable lower bracket. Additionally, it offers Tein's signature 16-level damping force adjustment, enabling fine-tuning for various driving conditions. All threading components are treated with a special fluorine coating to prevent rust, and lower brackets receive electroless nickel plating with clear painting for enhanced corrosion resistance. The Super Drift system includes helper springs and linear springs made from high tensile steel with a tensile strength of 200kgf/m m2. A unique conical spring washer is incorporated between the bracket lock and lower bracket to prevent loosening during hard use, a crucial feature for drifting. The setup is optimized for use with commonly fitted larger wheels and tires. Compatibility is specifically for the Nissan Silvia S15 SR20DET model, produced between January 1999 and August 2002 (JDM only). Compatibility information is provided by the manufacturer and may not guarantee fitment for all vehicles; independent research before purchase is recommended. This product is noted by one user as being very stiff and too harsh for a daily drive, but excellent for track and drift applications.
