This adds some fore/aft stiffness to the ZX6 without adding too much to the twisting flex. This helps prevent the center driveshafts from dropping out of the diif or slipper drive cups. The Flex deck is made from glossy 1.6mm glossy carbon fibre, the Flex option being for lower to medium grip surfaces.
This is a replacement should you break one, also available as an overall kit
KY308. Price is for ONE rear deck only.
