Sparco Seat Bases utilize the factory seat mounts on your vehicle's floor and provide a flat surface for mounting your Sparco seat. All seat bases are vehicle specific and provide a 100% bolt-in installation.

The 600 Series Sparco seat base is constructed with 3/16" thick steel to provide a strong flex-free mount. In addition to the mouting holes provided for standard bolt-on installation, the Sparco base has a wide metal platform to allow custom mounting of side mounts direct to the base (drilling required). This direct installation is an option for race vehicles where the lowest seat position is desired. The base is powder coated in a black wrinkle finish. 

In order to properly install a Sparco seat in your vehicle, you will need one (1) of each of the following, per seat:
