Sparco 600 Series Seat Bases utilize the factory seat mounts on your car or trucks floor to provide a flat surface for mounting your Sparco racing seat. These racing seat bases are vehicle specific for an easy, bolt-in installation. The 600 Series Sparco racing seat bases are constructed with 3/16" thick steel to provide a strong flex-free mount. These racing seat bases are powder coated in a black wrinkle finish for a cleaner look. In addition to the mounting 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.
