Description:

Tarett Engineering has put this kit together to upgrade the springs on your 991 GT3. Choose between our Sport kit with 560 front and 672 rear spring rates, our Track kit with 672 front and 840 rear spring rates. Both kits will 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 springs for this kit because they are the lightest, strongest, highest quality springs on the market today. Together with the needed helper springs and spacers, this is a complete drop in spring upgrade kit.
