06-15 NC Mazda MX-5 Slider Seat Mounts (Left)

Upgrade your 2006-2015 NC Mazda MX‑5 (NC) (Miata) with a premium racing-grade left-side seat mount: the PCI Slider Seat Mount SM-06MX5-L-S2. Designed by Pro Car Innovations, this mount uses a one-piece 3 mm (1/8″) carbon steel base and side mounts with precise CNC laser cutting and bending for maximum strength, stiffness and weight savings. Unlike older heavy welded 3/16″ designs, the SM-06MX5-L-S2 harnesses engineered bends and sectional reinforcement to achieve equal or superior performance.

Featuring PCI’s S1 high-strength sliders (each slider bolts with four bolts to the base) for exceptional stability and adjustability, this mount accommodates 5-point and 6-point sub-belt harness setups, and long-travel fore/aft adjustments to dial in your driver position for street or track use.

Finished in a full gloss black metallic powder coat (including all side mounts), with grade 10.9 and grade 8 hardware, this mount looks as sharp as it performs. The wide adjustment range (14.75″ to 17.5″ width for standard side mounts; for MX-5 versions it’s 1″ narrower) and 9.625″ front‐to‐back travel give flexibility for different seat styles and driver ergonomics.

Whether you’re building a dedicated track car, high-performance autocross Miata or simply upgrading your driver cockpit for aggressive driving, the PCI SM-06MX5-L-S2 delivers race-ready mounting, adjustability and peace of mind. No guesswork. No off-the-shelf compromise. Just precision fitment, strength and flexibility.
