Product Details

Convert your 1989-2005 NA/NB Mazda MX‑5 (Miata) into a driver-centric machine with the PCI Pro Car Innovations One-Piece Seat Mount SM-90MX5-S5L (left side). This mount is engineered from a single piece of 3.4 mm (≈ 1/8″) carbon steel, laser-cut and CNC-formed with no welds for exceptional strength and precision. According to the manufacturer, this design achieves equal or superior rigidity compared to traditional 3/16″ welded mounts. 

Designed to bolt directly into the Miata’s factory seat‐mount points, installation is straightforward—no major fabrication or guesswork required. With multiple seat mounting holes and integrated sub-belt mounting locations for 5-point and 6-point harness systems, this mount is built to support serious track setups or high-performance street configurations.

Finished in a black wrinkle powder coat with stainless laser-etched logo plates, this mount not only delivers motorsport reliability but also cleans up your cockpit. Whether you're installing a lightweight race bucket for autocross, a harness-equipped seat for track days, or simply upgrading your driver’s ergonomics for spirited street driving, the SM-90MX5-S5L gives you peace of mind, adjustability and proper fitment from day one.
