SEAT MOUNT RH 93-07 SUBARU WRX/STI

The SEAT MOUNT RH 93-07 SUBARU WRX/STI by SPARCO is purpose-built for enthusiasts upgrading to performance bucket seats on second and third-generation WRX and STI platforms. This right-hand mount serves as the critical interface between a race-spec or sport bucket seat and your vehicle's factory floor pan, enabling the transition from OEM seating to lightweight, high-bolster designs that prioritize driver retention during aggressive driving. Whether you're building a track-focused machine or upgrading your daily driver's cockpit, this mount eliminates the compromise between comfort and performance.

SPARCO engineering ensures this seat mount maintains precise fitment geometry to the 93–07 WRX/STI platform while distributing driver load efficiently across the floor structure. The design accommodates the lateral G-forces and vibration loads common in both road course and rally environments without flex or rattle, a critical consideration when integrating aftermarket seating into Subaru's unibody architecture. At 8.5 lbs, the mount contributes minimal weight penalty compared to factory hardware, and its compact footprint (18 x 4 x 18.5 inches) integrates seamlessly without interfering with other underbody modifications like exhaust tuning or transmission upgrades.

Buyers installing aftermarket bucket seats on 1993–2007 WRX and STI models will find this right-side mount essential for completing a professional interior transformation. Mechanics and shop technicians value SPARCO mounts for their consistent bore spacing and mounting-point alignment, which ensure repeatable installation across multiple builds and minimize custom fabrication time. Proper installation requires removing factory seat hardware and floor brackets; verify compatibility with your specific seat model before ordering, as mount configuration varies between left and right sides.
