Complete fitting kit: side mounts included. This frame comes with its own side mounts, so any side mount bucket seat bolts straight to it. You only need the seat and the frame, with no separate side mounts to buy. The slider is built in as well, so no separate runner kit is needed.
A PCI Racing sliding sub frame for the Mazda MX-5 Mk4, the ND chassis, 2016 onward. Part number SM-16MX5-S2.
The ND is a different car underneath from the NC before it, so a mount for a Mk3 will not fit. Order on the chassis code rather than on the model name, and send us the registration if you are not certain which you have.
Slider, and why
This is the slider version, so the seat moves fore and aft after installation. In an ND that is worth more than it sounds: these are still largely road cars, and being able to move the seat back to get a bag behind it, or to let somebody else drive, is the difference between a car you use and one you only take to track days.
PCI’s slider bolts to the base with four bolts rather than the usual two, which they rate as twice as strong as two bolt mounting. With a harness pulling on a seat rather than a seatbelt, that is the right side to be on.
Construction
Laser cut and CNC formed from a single piece of 1/8 inch carbon steel, with bends adding stiffness where thicker metal would otherwise be needed. Gloss black powder coat, grade 10.9 8mm hardware, five and six point sub belt mounting locations built into the mount.
Ordering
Side mount only, for a competition bucket, bolting to the factory seat mounting points. Handed, so order twice for a pair.
