Any special material? I understood just about any steel will do, even mild steel tube or bar. Not so?
Cheers,
I was thinking 4140. Excerpt from here:
viewtopic.php?f=38&t=19628&p=244551&hilit=swaybar#p244551“As far as bar size, the stock miata bar would work well but you need extensions from the frame to reach the bushing locations. Just above and behind the lca shoud fit best. If you want to make your own, that can be locost too. A 4140 rod already hardened is about $50 for 3 feet, shorten to the outside rail width plus 2 inches each side, have a machine shop drill the ends for a 7/16 bolt, fit nylon tube to act as bushings and 1x3x4 aluminum pillow blocks to drill for 3/8 bolts, split in half, then bore to fit the bush od. Fab the ends from tube and 1/8 strip at 45 degrees to the bar.”
Of course, you could anneal the bar by heating to bend it then heat treat but my suggestion is more locost. You could also rework an oem bar though a lot of them these days are hollow and yards won’t resell them since they get tweaked so easy. I said I don’t care if it is bent a little because I will fix it but no dice.
