Pro Car Innovations Racing Spec Seat Mounts takes the guessing game out of this install. Finding the correct seat brackets can be almost impossible where most end up with a self-fabricated mount. The PCI S1 sliders are one of the strongest sliders available. Each slider bolts to the base with 4 bolts making them twice as strong as 2 bolt mounting. PCI has invested the research in order to create an ingeniously crafted safe design that’s easily adjustable to accommodate multiple applications.
