Upgrade the passenger-side of your 1989-2005 NA/NB Mazda MX‑5 (Miata) with the precision-engineered PCI One-Piece Seat Mount SM-90MX5-S5R from PCI Pro Car Innovations. Crafted from a single piece of 3.4 mm (~0.135″) carbon steel using CNC laser-cut and bent technology, this design delivers outstanding structural strength and weight savings by eliminating welds and leveraging smart geometry.
This one-piece mount bolts directly into your Miata’s factory seat-mount locations, eliminating the need for self-fabrication and maintaining clean, precise fitment. With multiple seat-mounting holes and integrated sub-belt mounting for both 5-point and 6-point harness systems, this unit supports serious track-day builds as well as performance street setups.
Finished in a black wrinkle powder coat with stainless steel laser-etched logo plates, the mount not only functions like a racer’s component but looks the part too. Whether you’re installing a lightweight racing bucket, harness system, or simply optimizing your interior for aggressive driving, the SM-90MX5-S5R offers simplicity, strength and direct fitment. Install with confidence and drive centered on performance.
