The Sparco 600 series seat base is a direct fit mounting bracket that adapts a Sparco or compatible racing seat to the factory floor mounting points of the Nissan GT-R. It is formed from 3/16 inch steel for a strong, flex free platform and bolts to the OEM seat mounts with no floor modification. A wide flat top surface also lets side mounts be fixed directly to the base for the lowest seating position. This is the passenger (right) side base.
