I know Kirkey wants you to hard-mount it to the roll cage, but there is a 9 inch height difference between the people on our team, so we need the slider. I ordered a sliding mechanism from Sparco and the side-mount towers that go with it with the hopes of modifying that to suit my needs.
Thanks
We run a Kirkey on sliders. When Kirkey says they want it mounted to the roll cage, they're talking about mounting in a tube frame car, not one like our MR2 that has a big hump in the middle of the car for the fuel tank. Since I couldn't mount them to the roll cage, here's how I do it. I don't use the side-mounts at all, they just complicate this unnecessarily; also, I sometimes have some very tall drivers and in our MR2 they need all the head clearance they can afford under the roof, so any additional height above the floor is unwelcome.
I am using this OMP slider:

I have it attached directly through the bottom of the Kirkey seat using some round-head allen bolts to the top of the slide. Then the bottom of the slide is bolted to the floor (through the floor, actually) with large spreader plates under the floor. I use a number of large washers as spacers above the floor to keep it flat/planar because the sliders don't like to get out of plane, otherwise they rack and don't work right. The spreader plates on the bottom are to keep the seat from pulling free of the floor sheet metal in the event of a hard collision.
Attaching it through the floor in this manner is made easier if you weld the bolts to the slider tracks (the stationary part) so that they don't want to move around while you're trying to bolt it down from under the car.
If you have the vertical room, you can build a bracket that attaches to/through the floor and to which the sliders mount, but I don't have that luxury.
FWIW, the sliders work great, have a very positive actuation, and everybody I know who's used them has been happy with them.
We use the I/O Port seat back brace to make sure that there's no movement of the seatback in the event of a collision:

Good luck!
