doesn't look terribly comfortable, but it does seem reasonable and effective.

Dangerous? -at least get a seat that is FIA or approved by some safety board. That's like trying to make your own helmet!

Dont skimp on safety equipment like helmet, seat, harness, etc... in a track car.

show me a safety aproved seat other than a FIA approved seat...

As long as your welds are good that seat is safe.

Hell... in the SCCA you can use those plastic dune buggy seats if you wanted. Those are authorized as well.

By all means go for it then.

I value myself a little more than that. Although: if I did haveto run a metal seat (let alone a seat that I made like that), then I would use 2-part foam or beads to make a foam or bead seat that is moulded to my body. I think it's $40 for the 2-part foam or $1,100 for the bead seat. -I would highly reccomend the foam, it's cheap and it will greatly reduce injury in a crash, plus it's much more comfortable.

if you have the aluminum. a sheet will run you almost as much as a seat. I have found them for $230 or so for a road race seat.

did alu prices go up like steel has? alu has always been kinda spendy anyway, moreso than steel.

its neat.. but i dont know if you'd be saving any money at all.

Yeah see that is without the cover. I would hope this rorty seat would accept an available seat cover.

It's no different than a Kirkey or similar aluminum seat. With proper mounting, they are as safe as any other seat. The FIA seats are definitely nice but they are the shape that they come. With the metal seats they can be tweaked to fit perfect.

A mig, properly outfitted, would work. The Kirkey seats are mig'd. Tig would be nice though.

I purchased a Kirkey seat. one mean piece of kit. 100% MIG'ed. I am actually going to add the head containment stuff to mine, and that will be MIG'ed as well.

Yeah I have a Kirkey intermediate road race seat. It is pretty nice. One beef though. The cover ripped WAY too easy when I was putting it on the seat. Right in the corner under your arm. You have to sort of pull it over the bolsters and it just ripped with very little effort applied. Another good part about the metal seats is that you can bend them to fit your body better than a composite seat would fit.

How about some threadcromancy....

What kind of realistic weight are we looking at for aluminum seats from say "Ultrashield"?

Anyone have a take on aluminum or composite being better for seats?
