The Swift Springs Z65-178-100 is a high-performance metric coilover spring engineered to enhance your vehicle's handling and traction. With a 65mm inner diameter, a 7-inch length, and a precise 10 kgf/mm (560 lbs/inch) spring rate, this component is designed to offer a noticeable improvement in driving dynamics. Swift Springs utilizes over 90 years of industrial spring manufacturing experience to develop their products. The Z65-178-100 is constructed from Swift's proprietary (HS5.TW) material, which is significantly superior to silicone chrome steel. This advanced material allows for a more efficient spring design with fewer coils, leading to reduced unsprung weight and an increased stroke without compromising durability or linear spring rates. These advantages contribute to a more confidence-inspiring driving experience, whether on the street or the track. Swift's metric coilover springs are available in a wide range of inner diameters (60mm-70mm), lengths (102mm-254mm), and rates (3kg-50kg) to cater to diverse application needs, from comfortable daily driving to aggressive race setups.
