981 GT4 Spring Upgrade Kit


Tarett Engineering has put this kit together to upgrade the springs on your GT4 to 448 front and 560 rear. A perfect combination  for hot street and track use, these spring rates will reduce body roll and improve suspension response. The rates are within the range of the OEM  GT4 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.
