Swift Metric Coilover Springs are made from a proprietary (H5S.TW.) Material.
This allows Swift Springs to manufacture a spring that is has more stroke, increased traction and handling as well as a spring with less coils, resulting in a lighter spring with less unsprung weight.
The same springs are used in Super GT, Formula Nippon, F3, F3000, Super Taikyu, IMSA, Pirelli World Challenge, Rally America, VLN, Le Mans Series, Formula Drift, and many other professional racing avenues.
Since the metric system is used widely in the sport compact and road race market, we have introduced the metric line of coilover springs to reduce confusion and to better cater to our customer's needs.
Our metric coilover springs come in various sizes with inner diameters ranging from 60mm (2.25in) to 70mm (2.75in), spring lengths from 127mm (5in) to 280mm (11in), and spring rates from 3kg (168lbs) all the way up to 34kg (1900lbs). Whether you are looking for a comfortable ride for your commuter or a more aggressive setup for your race car, we have the right spring for your application!
