Sparco 400-Series Seatbase Adapters for all Porsche 996, 997, Boxster and Cayman Sportscars.


Sparco seat adapter bases are custom designed to allow for easy installation of Sparco seats to many popular makes and models of vehicles. The design adapts the factory mounting locations of the vehicle to fit Sparco aftermarket seats and include seat belt mounting locations where possible.

All seat adapter brackets are primarily intended for bottom mount style seats. Although they can be used with most side-mount style competition seats, varying seat widths and other design factors may limit installation possibilities. Please check measurements of your seat to determine final fitment in your vehicle, or contact us with any specific concerns.

Warning: Adapter kits and most aftermarket seats do not facilitate the transfer of many modern vehicle electronics, such as airbags and/or seat harness circuitry. Please consult your factory service manual before installing any after-market merchandise and INSTALL AT YOUR OWN RISK.
