Description:
This is the base that gets your Sparco seat sitting right — a genuine Sparco 600 Series seat base, built specifically for the 1990-1996 Nissan 300ZX. Sparco seat bases use your factory seat mounts on the vehicle floor, giving you a flat, level surface for mounting your Sparco seat — no floor pan modification needed.
Constructed from 3/16" thick steel for a strong, flex-free mount, this base is a 100% bolt-in installation using your factory floor mounting points. Beyond the standard bolt-on mounting holes, the base includes a wide metal platform that allows custom side mount installation directly to the base (drilling required) — an option for race builds chasing the lowest possible seat position. Finished in a black wrinkle powder coat that matches the rest of Sparco's lineup.
Choose your side — driver, passenger, or grab the pair to do both seats at once — and pick standard or low mount height depending on how aggressive you want your seating position.
But this isn't just about bolting a seat in. It's about a mounting point that actually fits your car's floor — no shimming, no fighting bad geometry, just a clean, solid platform for your Sparco seat. Whether you're building a track car or just upgrading your 300ZX's seating, this base does exactly that.
