Vaugh Machine did it in LA. Kinda pricey. Weldcraft was 20 a rim, this was 300. But This company doesn't do a band like weldcraft. Never heard of a band failing, but aluminum is so weak when it's welded, we figured with the HP safer to have only one bead. Not sure on the material, but if I had to guess, it's cast or billet. But I would lean towards billet. Where he machined, it doesn't look cast. I also looked at the weights, and one of the them ONLY has two small weights. Very little needed. Never seen anything only need that amount.
