Turns out 150+ miles in a kirkey with no bottom pad and setup for a HANS that you are not wearing in 85 degree weather while roasting like a chicken in a oven is fun. Like I have not had that much fun in a long while. But my butt is shot. Like where there was a butt there is no more. Like some sort of SyFy energy being has removed its feelings. I have no feeling in my posterior. I am out of butt innuendo. My butt hurts guys. IT also might have something to do with the fact that when I set down its on my tailbone and not any other part of me.
Is there some sort of magic memory foam seat bottom insert for a Kirkey that I don't know about to make them comfortable because right now is a little bit of fire resistant fabric and a big plate of steel. The foam that separates your legs is fine at the front of the seat but its more a wedge and it does not run all the way to the back of the seat its just metal the last 8 inches or so to the joint. I have one of the lumbar foam inserts which in retrospect would have been a good thing to take on the trip.
Or am I going down to UFO foam and buying some scraps to sew into the seat.
Confor blue memory foam. It's the bomb. Don't go for "mattress topper", I've tried both and it's 30 minutes vs 13 hours comfort.
Let us know what works. I will need to do something similar for my kirky seats whenever I get my car running.

I can get a blue memory foam pillow locally and just hack it up right. All I need is a maybe 10 x 8 x 4 inch pad of the stuff to get this to work.
If your blue memory foam is the Confor stuff, sure. It's pretty dense. I use a 1" thick pad.
Don't people stroke out on long airline flights because of this?

This. Mattress topper isn't close to dense enough for a seat pad. Most of them aren't dense enough to use as a mattress topper.
I use a hunting tree stand pad, I found in Wally's World, in my kayak. I hacked it up to be form fitting to my posterior and it's good for all day. It's all about spreading the load evenly.

They seem to be the only other place I have found that sells the stuff other than mcmaster.
You can get it from medical supply stores and Pegasus Racing - they call it Backsaver foam.
Would this stuff work under a vynilcover? Ive got redo the seat inmy truck and I want a 10 hour seat.
Its a bench that fits me great, but current materials are shot.
Pulled seat apart and there are absolutely no padding underneath the butt. They did a miata foam excotomy on the seat and there are a few screws that had worded there way down there. Used the pressure washer to clean the covers and strip off the little foam that remains. Going to UFO to get some good foam and pickup some good glossy black for the wheels. Need to order brake pads as well.
Also look at how the seat is mounted. When I put the Kirkey in the Locost I kept the bottom level and had that issue. When I did the Sprite I angled the seat back a little to put my legs at less of an angle with my torso. This definitely helped some.
In reply to wearymicrobe:
Build thread?
Just a thought - is there a safety concern, regarding fireproofness, with the foam?
Or am I just overthinking?
It's urethane, it will burn rather well.
The Kirkey cover is fireproof though right?
Kirkey sells the covers for not a great deal of money. I've got a good Kirkey roadrace seat, and have never had any butt troubles with it. Its amazing what an inch of good foam will do.
Their (or anybodys) cheap flat panel seats suck in many ways, but the contoured ones I've found to quite decent.
For me, with long legs, support under the thigh is critical. If I don't have that, I'm suffering in 10 minutes.
That blue memory foam was the ticket. Trimmed some up to fit in the gap from the foam that was left then added another inch across the whole seat pan. Leaned the seat back maybe another 5 degrees and presto its comfortable for the 45 minute shakedown that I did.
Cobra's are fun, properly setup cobras are even more fun, good seats even better. Add in scrubbed RA-1 holy E36 M3 snacks. Above 80mph though the thing is a brick due to the aero. Going to have to get comfortable street tires if such a thing exists. The RA's are stiff.
Blue foam worked great for my Kirkeys...
Where/what was the proper blue foam?

Google "confor blue" and you'll find a bunch of suppliers.
Here's the stuff at Pegasus with a rubber backing attached.

I've never had any problem with my butt and my Kirkey while on track, or at an autocross … but the 2 + hr drive to and from is a PITA ( 
)
I just use a variety of different pads to make it livable … take them out when I get to the site
