Sparco 600SB059L Series Racing Seat Base - 600 Left Side

The Sparco 600SB059L is a vehicle-specific, left-side seat mounting base from Sparco's 600 Series lineup. Engineered to bolt directly into your vehicle's factory seat mount locations, this seat base provides a solid, flat platform for properly installing a Sparco racing seat without permanent modification to your floorpan.

Constructed from 3/16" thick steel, the 600 Series base delivers a rigid, flex-free mount that holds up under demanding street and track conditions. The wide metal platform also allows for direct side mount installation for competition applications where the lowest possible seat position is required—though this method requires drilling. The base arrives finished in a durable black wrinkle powder coat for corrosion resistance and a clean appearance.

Key Features:

• 3/16" thick steel construction for maximum rigidity
• Vehicle-specific design — 100% bolt-in installation using factory floor mount points
• Wide platform accommodates both standard bolt-on and direct side-mount configurations
• Direct side-mount option lowers seat position for race use (drilling required)
• Black wrinkle powder coat finish
• Left-hand (driver) side position
