Description

The K-Tuned Z65-203-120 is a metric coilover spring designed to offer improved performance and feel for both daily drivers and race cars. Manufactured by Swift Springs USA using their proprietary HS5.TW material, this spring boasts a superior quality and performance compared to standard silicone chrome steel. This specific coilover spring features an 8-inch length, a 65mm (2.56-inch) inner diameter, and a spring rate of 12.0kgf/mm (672lbs/inch). It provides a usable stroke of 92mm (3.6 inches) and a maximum stroke of 125mm (4.9 inches). The material, HS5.TW, is noted for its advanced properties, contributing to increased traction, seamless weight transfer, better ride quality, and more predictable handling. Swift metric coilover springs are color-coordinated based on their inner diameter, offering a wide variety of lengths and rates to suit different applications. This particular spring is sold only in pairs.
