Product Description

The Sparco 600SB206L Left Seat Base is a performance-oriented seat mounting solution engineered specifically for Subaru WRX and WRX STI models from 2015 through 2021. Built from thick, durable steel and finished in a corrosion-resistant black powder coat, this seat base provides a strong, flat platform to mount most Sparco seats directly to the vehicle's factory floor mounts. This base maintains structural rigidity and provides a secure foundation for both fixed back and reclining racing seats, making it ideal for motorsport or spirited street driving.

Installation is straightforward with bolt-in compatibility to Subaru's original seat mount locations. For seat sliders or custom side mount setups, additional hardware (track sets and mount kits) are required but sold separately. Whether you're upgrading to a lightweight racing seat for track days or simply improving driver support on the street, this Sparco seat base delivers precision fitment and reliability.
