I had some made very similar to that for an Evo 2. To get the seat low enough for a 6' driver to stay below the roll bar (MiataCage.com cage, no roof) to pass tech, we had to mount the seats on the floor, and had to clearance out the tunnel where it bulges inward for the catalytic converter.

I never got back to you guys on the Kirkeys. They were the 16" wide ones and they fit with room to spare. 17" wide would be no problem as well. I am 6'1" 180lbs and they are super comfortable. I know you wouldn't believe it just looking at them because they are flat, hard metal but the contoured padding is really supportive and comfy. It is like they know my ass by heart. It's almost like sitting on a bag full of butterflies...yeah, maybe that's not a good description. Lateral support is really good and the wings of the seat back cradle my torso at the ribcage even with the bottoms of my proud pectorals. They do not interfere with arm movement and I can still raise the top while seated if I am unbelted, though it takes a little contorting. The flat rear portion of the seat bottom is bolted directly to the floor to allow broomstick compliance. This creates a small natural rake to the seatback that feels perfect. It sits just as it is pictured here:

The front mount is set up with a pair of one inch wide flat straps that have been hammered over a wood block to bend them to the appropriate angle. They run from the stock front mounting holes back toward the rear of the seat. Intersecting those bars at a 90* angle is a one inch piece of box tubing that is simply used as a spacer between the front of the seat bottom and the flat bar. Bolts run through the seat bottom, the square tubing, and the flat bar and there are nuts and washers on the bottom. It is so secure I cant even wiggle it.

And for you sweaty guys the cover/padding unsnaps and is gently washable in case it starts to get the funk.

Crappy cell phone pic!

Someone needs to get fabbing and create a group buy for seat mounts. I'd pay $150-$200 for a pair of mounts. The pitgarage people aren't answering their phone at the moment so Ihaven't ordered my side mounts yet.

Those seats look good!

I got the same kirkeys as sixshooter. They suck for DD, but once you're in them, they are great.

actually, I have some already made. I'll post pics once i get some. These aren't your normal seat mounts though, this is a full base with side mounts, completely adjustable.

How are they to get out of with the non tilt stock steering wheel?

Sparco Corsa on custom rails/pit crew brackets, as low and far back as possible.

Get posting pics!

The steering wheel is never a conflict. You won't ever find it in your way because the seats sit nice and low. The issue he is referring to is that you don't swing your legs out the door and stand up like you do with low sided seats. You have to use your arms to lift yourself up before swinging a leg out and putting a foot on the ground. I end up with one hand on the door sill and one on the center console to lift myself enough to swing a leg out. All racing seats with high sides are similar in this regard. It is the same in my buddy's GT-R with his fiberglass Cross, Bride, Momo or whatever brand they are. It is supposed to make it hard to fly out of them by accident. :) They are plenty comfy when you are in them. Like Bond says, "...once you are in them they are great."

Custom made. His name is Adam Griffith. Just moved to NC and does alot of custom rx7/m3 work (cages, aero, tow hooks, pedal boxes, alum. door cards etc) He should be easy to find on rx7 forums.

these were made by my good friend at Pro-Car Innovations. Kinda on the expensive side though, but its great quality.

How much are they?

PMed

did you get them.

Any updates on the 949 brackets.

There is a little extra R&D going on for the passenger bracket. As soon as those pretty ones above are ready, I'm getting a set. Shouldn't be too much longer.

nice, priced similar to their brackets for other cars?

It looks like you might have found someone making these, but I could definitely get a seat mount group buy going if there's enough interest.

you need to get started as
I is ready now

Sparco Circuit FIA seat.

Got it for $350 with sidemounts from a wheel to wheel racer right when it went out of date.

I removed the bottom pad so that I sit even lower in it. Yes, that means I'm sitting on fiberglass covered in fabric.

Impressions: Love it on the track. A total pain driving to/from the track. The sides are super high and narrow which means you're not going anywhere when you're flying through a corner, but you're also not going to be moving even half an inch once you're in the seat, and you better not have anything in your pockets. Because it has a halo, you can't check your blind spot when changing lanes - so I got some convex mirrors. To me, it's worth the compromises.

Mounting can be done DIY but it's a huge pain, for a while I had the sidemounts bolted to a corbeau bracket, but it was never quite right or centered. Now I have had custom mounts done with modification to the transmission tunnel to get the seat down on the floor and perfectly centered. Much better.

I just ordered a set of these.
