GT4 Performance Springs All aluminum mounting brackets forGT4 Swift Spring upgrade kit: Upgrade your stock springs to 448lb in front and 560lbs in the rear! These spring rates have shown to reduce camber loss during cornering and can improve tire wear while on track. Fortunately the factory OEM shocks are capable of handling these stiffer springs without the need to revalve. Stiffer spring rates are also needed to handle higher aerodynamic loads. These springs will help compensate for the increased loads.
