SEAT MOUNT LH 2019+ TOYOTA SUPRA

The SEAT MOUNT LH 2019+ TOYOTA SUPRA from SPARCO is a precision-engineered seat adapter bracket designed for drivers who upgrade to performance racing seats in modern A90 Supra models. This left-hand (driver-side) mount bridges the gap between OEM seat attachment points and aftermarket racing seats, enabling serious enthusiasts to install competition-grade seating without extensive chassis modification. Whether you're building a track car, autocross competitor, or street performance machine, this adapter ensures secure, bolt-in compatibility with Supra 2019–2022 chassis.

Constructed from high-strength steel and finished with durable black powder coat, the SPARCO 600 Series seat mount (MPN 600SB367L) resists corrosion and vibration-induced wear in demanding driving conditions. The bracket's rigid geometry maintains seat position and fore-aft adjustment travel, critical for safety harness fitment and optimal driver ergonomics during high-lateral-load events. At 8.73 lbs, the mount adds minimal unsprung weight while delivering the structural integrity required to handle repeated acceleration cycles and sustained cornering forces typical of road racing and weekend track days.

This adapter is essential for Supra owners installing SPARCO 600 Series or compatible fixed-back racing seats that lack factory-matched mounting tabs. Installation is straightforward for those with basic mechanical skill—the bracket bolts directly to original seat rail mounting locations, preserving seat adjustment range where applicable. A right-hand mate (sold separately) is required for two-seat setups. Verify your specific Supra model year (2019–2022 covered) and seat model before purchase to ensure correct fitment and safety compliance.
