991 GT2/GT3 RS Spring Upgrade KitDescription: Tarett Engineering has put this kit together to upgrade the springs on your 991 GT3 RS and GT2 RS. Choose between our Sport kit with 560 front and 672 rear spring rates, or the Track kit with 672 front and 840 rear. These spring rates will significantly reduce body roll and improve suspension response. The rates are within the range of the OEM GT3 dampers without needing to be revalved. Other rates available on request. We chose Swift
