Sparco 600SB313L 600 Series Left Side Seat Base

The Sparco 600SB313L is a vehicle-specific seat mounting base designed to provide a secure, professional installation platform for aftermarket Sparco racing seats. This left-side (driver side) seat base utilizes your vehicle's factory floor mounting points and provides a flat, stable surface for mounting bottom-mount or side-mount performance seats.

Key Features:

• Constructed from heavy-duty 3/16-inch thick steel for a rigid, flex-free mount
• 100% bolt-in installation using factory seat mounting holes
• Durable black wrinkle powder coat finish for corrosion resistance
• Wide metal platform allows custom side-mount installation (drilling required)
• Pre-drilled mounting holes for standard bottom-mount seat installation
• Vehicle-specific design ensures proper fit and positioning
• Sold individually - one base required per seat

Installation Requirements:

To complete a full seat installation, you will need this seat base plus additional components sold separately: a track set (Sparco #00493) for fore/aft adjustment, appropriate mounting hardware kit (#50001 for bottom-mount seats or #50002 for side-mount seats), and side mounts if installing a competition-style seat. The wide mounting surface allows direct mounting of side mounts for dedicated race vehicles where the lowest possible seat position is desired.

This is a left-hand (LH) seat base, meaning it is designed for the driver's side position when sitting in the vehicle. Sparco seat bases are engineered to work seamlessly with Sparco racing seats and provide the foundation for a safe, secure aftermarket seat installation.
