16+ ND Mazda MX-5 Slider Seat Mounts (Left)

Upgrade your 2016+ ND Mazda MX‑5 (Miata) with a race-quality, highly adjustable mounting solution: the PCI Pro Car Innovations Slider Seat Mount SM-16MX5-L-S2 (left side). Built from a single piece of 3 mm (1/8″) carbon steel, laser-cut and CNC-formed for superior strength, stiffness and weight savings. Unlike conventional rigid 3/16″ mounts, this design uses smart bending and reinforcement to achieve equal or better structural integrity while being lighter and cleaner in look.

The S1 high-strength sliders included mount to the base with four bolts each—double the strength of typical two-bolt slider setups. The mount boasts wide adjustability including width, fore-aft sliding (9 5/8″ travel) and accommodates 5-point or 6-point sub-belt/harness mounting, making it ideal for both street enthusiast Miata builds and full track-day setups.

Finished in a gloss black metallic powder-coat on both the base and side-mounts, equipped with Grade 10.9 / 8 mm hardware and black nylon spacers, the SM-16MX5-L-S2 marries premium aesthetics with motorsport functionality. With width adjustability from 14 ¾″ (375 mm) to 17 ½″ (445 mm) for standard side mounts (and wider options available) it’s tailored for fitment flexibility.

Whether you’re installing a lightweight race bucket for autocross, a harness-mounted track seat or a finely tuned street setup, this mount gives you the control, the fitment precision and the adjustability to dial in your position and bolster your performance. Bolt-in, tune fast and keep your driver setup locked down for real performance.
