Wow that looks amazing. If you know what you're looking at, and I think I do, its even more impressive.

I can remember thinking a nice Art Morrison subframe looked pretty hot with the Corvette parts on it many years ago. Compared to this frame those seem more like a Street Rod IFS Mustang II crossmember setup you still see advertised.

Wow, definitely some rugged looking parts right there! Nice!

That's quite the jungle gym you have back there! Awesome work, and extra props for TIGing everything! We're tuned in to see whats next.

Thanks. I'll do mile runs with the car and the flats, so car can run upwards of 270 mph...wanted a little extra cage!

I'm going to say it takes 3 to 4 times as long to TIG it than MIG it. Still wondering why I'm doing it that way...

How are the seats mounted to the floor?

I have DOM bars that connects to the cage and runs along the floor. From this, Butler sent me tabs to weld on and then a 1" .063 square tube bar is attached to the seat. Like this (not my car, but snapped these at Butler when I was there):

That front end is a thing of serious thought and planning. I don't even know how to cut the slots for all of those adjustment slugs, but wow, the level of precise adjustability on all of the parts is just nuts. I'm also impressed with the diversity of tubing (no bendy round tube!) used on the subframe; I've been trying to use more 1x when it's possible, along with thinner-wall tubing. Clearly, Ron Sutton knows how to calculate where you need what for certain load paths, which also helps in weight management.

If you haven't yet, you might want to compare the brackets used on Kirkey seats. While the sliding adjustments on the Butlers shown may seem convenient . . .

Keep up the killer build!

Do the Butler seats not have integral places to run bolts through on the sides like the Kirkey seats ? Been thinking about getting a Butler seat but looking at that picture I'm not sure I see any way to use my current brackets.

Do you have other pictures of Butler seat mounts ?

You drill the holes for the bolts on Butlers. They double up the aluminum in the area where you would attach them. Butler provides a sheet to tell you where they recommend you drill them.

Seriously am I the only one that is going comment on this.

270 mph is scary fast !!!

Kudo's to you for building a cart that can safely do it.
