Thanks Concealer404...
The cage is a kit from Advanced Autosports. Of all the cage kits out there I just liked some of their features the best... I was very very pleased with the product. The cage is built to maximize room and I need that for a guy my size. The only thing I would change or modify would be the door bars. I would have preferred them to go out to the door skin.
But I would definitely recommend this for the DIY'ers. Just have to take your time and measure 5 times - cut once and take small copes until each bar fits like you want it to....

I'm looking to finally install a seat in my miata. I have been eyeballing the Sparco Circuit and the Sparco Pro ADV TS due to their size. I'm a rather "tall" and "skinny" guy. So at 5' 10" and 150lbs, will I fit snug in either one of these seats? There isn't a dealer within 4hrs of me otherwise I would try them out myself and I have reached out to some local miata guys for help too. Any other measurements I should be taking to figure this out?

The circuit 2 will fit you. It's going to have a bit of room in the Butt area but the height will fit you and a Miata.
the ADV is for bigger drivers. say about a 36 pants size.

Thanks. I need to make the drive up to VA and visit your showroom and test them all out. By chance will you have any demos at Road Atlanta next month?

I'll have a ProADV in my personal Miata kart. but that will be about it. You're more than welcome to pop out and try it. difficult to carry seats.

Default PCI Adjustable Seat Mount

I do not know if this common knowledge to those with PCI Adjustable seat mounts, but I use this little trick to help mount my seat that last smidge bit lower. The side mounts and base are attached together with a welded threaded bolt, backing plate, washer, and then finally a hex nut. I have found if you inverse the hardware, with the welded bolt on top, you can get a bit more clearance and can get your seat a fraction of an inch lower. This allowed me to use the next lower mounting hole on my side mounts.

Pictures.

With backing plates, washer, and hex nut on top the hex nut would foul the bottom of the seat. How I installed the first go around.



But if you flip the hardware....

Rear hardware is now flipped with welded bolt on top.

Front

Rear

Bottom of the mount. One pair of hardware mounted from the bottom, the other from the top, to illustrate difference.




Juuuust barely clears bottom of the seat, but can now use lowest mounting hole.



I hope this helps someone out in mounting their seat a bit lower.

I can get this for $150 is it worth it with the rip in the side? How well does the Champ-r fit in a miata? This would be a passenger seat to compliment a WRC-R that is yet to be mounted

Google the dimensions. To fit OEM door trim it needs to be narrower than about 500mm. Tall drivers need about or less than that same dimension to clear roll bar/cage main hoop. The discontinued OMP Grip fit with a bit of trimming for a tall driver.

I'm going to install a Kirkey 17" Pro Drag (Model 41) with a PCI adjustable base in the next few weeks. Anyone have pictures of their aluminum seat back brace configuration that they would like to share? I recently put an I/O Port brace into a Lemons car; it was easy to install and worked well. However, in reading through the Safety Thread, it was intimated that this brace was not optimal. I've searched extensively on this, and found a few pictures in build threads, but very little description of which brace was chosen or why. Thanks

This is the back brace for the Kirkey 41. They are not badly priced.

This is the link We send to Customers when installing an aluminum seat.

Also a little diagram for how a generic back brace is supported.

That's the seat I use. No pics of brace, though. Those seats are surprisingly comfortable. You can tuck a bit of padding beneath the seatcover for longer trips for seat bottom or lumbar assistance if you need it.

Yup those seats are comfy and the extra padding works well. I put a little extra just below and above the tailbone area to give my butt some cushion and my back a bit of lumbar. I regularly drive 142 miles one way in them and have driven 400 miles one way more than once. The drivers seat is 15 but the passenger seat is 17 to accomodate more robust bodies and back then, a child seat.

The picture is my co-drivers winter project. With all the snowfall we had in Florida this winter he must have gotten bored and decided to prepare for having air conditioned seats when summer arrives.

Thanks everyone. So OG- is that seatback brace preferred over the I/O port? If so, why?

I've had a 16 Track Dog Pro Race https://trackdogracing.com/ULS-RoadRace.aspx and while it was super comfy on the track with great support, going anywhere over 45 min long was literally a pain in my skinny *** due to pressure points and no lumbar support. It was better than other seats I've tried, but I don't understand how these very similar Kirkey's are so much better. Unless I just need to gain 50lbs so that my bones don't create too many pressure points. I'm kind of similar to Emillio in height/weight and I believe he is using a composite shell seats and not aluminum one.

3/8" or 1/4" sheets of memory foam on Amazon. Works wonders for getting a snug seat fit without pressure points

The seat back braces that we shared is made by Kirkey for your seat. it will bolt right on.
Why you don't want an IO post Style brace on an aluminum seat. The shape of a 'bar' and it's strength is parallel with the direction of the bar. When it comes to a rear impact that bar can remain in place while the seat is pushed back. The bar itself can then be pushed through the 1/16" aluminum sheet metal and into the driver's spine. This can cause severe injury or death. Kirkey's seat back brace is made from the same thickness sheet metal as the seat is made from. So in a rear impact the seat back brace will not punch threw but rather distort with the seat, thus reducing the chances of injury.
IO port braces do have their place and can be used with an expired FIA seat. FIA seats are much stronger than aluminum seats.

I'll ask my question in this thread since it seems to have devolved a bit from the original "catalog" style of thread...

I've done ~7 track days so far in my NB. I'd definitely fail a meaningful tech inspection, as my helmeted head is well above the Blackbird rollbar I have - I can't even have the top up without being majorly slumped down in my seat. As I plan to continue doing 1-2 track days a month with this org, it seems time to get seats and make things a bit safer (and have the ability to drive with NASA/SCCA and other orgs with real tech). I'd also like to stop having to readjust myself on every straight. I have an action cam mounted to my helmet, watching the video back it's crazy how much I end up moving around in the stock setup.

Was originally looking at aluminum seats, but after I buy all the bracing, it seems like I might as well just get a fiberglass seat. Anyone try fitting the OMP First-R into their car? Also, any tips on what to look for in a shop to do the install? I don't have a welder, and have no intention of buying one and learning on my safety equipment. I'm in Phoenix, but it doesn't look like any of the big names/vendors on the forum are from the area.

The choice is tough. You won't sit any lower than you will with an Aluminum seat. FIA seats are simply easy to install. If you're looking for a Safety Shop in AZ We recommend contacting We Don't Lift ( https://www.wdlracing.com/ ) they are OG racing dealers and well-respected racers int he AZ community.

A OMP first, We don't have any pictures of one in a Miata but they should fit based on measurements. naturally, all Fiberglass seats need some hammer time on the trans tunnel. Shoot me over your height, weight and pants size I can send you over what seats fit you and the miata.

Model: Style 47 (intermediate layback)
Brand: Kirkey
Size of seat: 16"
Side or bottom mount: bottom
Adjustable or fixed rails: fixed
Rail model: custom made
Driver height & weight: 6'0, 215 pounds
Fit in car: pounded trans tunnel out and cut off pieces of the seat; after that, very good
Driver fit : excellent
Construction: aluminum

Tall guy with long torso. Deleted rear seat mounting humps, made custom bracket, bolted through floor with load spreaders underneath. Had to cut off part of headrest and shoulder wing to fit with roll bar/ door cards.

I tried to use the Kirkey seat back brace with roll bar clamps, but ultimately the I/O Port brace just worked better for this install.

Brand: Ultrashield

Size of seat: 16"

Side or bottom mount: Bottom

Adjustable or fixed rails: Fixed

Rail model: TDR "Low"

Driver height & weight: 6'-0"; 215 lbs

Fit in car: Removed factory rear mounts, but otherwise no major modification required. Sits nice and low. Custom back brace.

Driver fit : Fits well, maybe a bit too roomy. I may add more padding, so the extra room will be helpful for this. I pass the broomstick test (wearing a helmet) with a Hard Dog Hardcore hardtop roll bar.

Link to seat or source: https://trackdogracing.com/TDR-RallySport.aspx

Link to rail or source: https://trackdogracing.com/Seat_Rails.aspx

Certifications: None

Construction: Aluminum

Weight: ~15 lbs

Custom back brace. It's a bit bulky, but I don't like the in-line harness bar braces. This mounts to the factory child seat bolts.
TDR Low rail (driver's side).
