picked up my wheels from OMF yesterday. they did a very quality job on the install onto my Weld SS II's. wasn't cheap, but it's what i wanted. i went with the black rings, and i still might powder coat the rims black too, undecided still though. OMF knurls both the ring and welded ring for grip on the tire. they also machine clearence for the sharp edge of the bead of the tire. instead of just a square corner where the edge can effect how the tire seats against the ring. they gave me a free shirt and a bunch of stickers(i did ask for them) but they gave them to me no problem. im very happy, cant wait to mount my tires. the "domes" they sell that goes at every other bolt location i decided to machine myself out of Titanium, still need to do that. they gave me one of their domes so i could copy machine it. they use steel inserts on the inside of the welded ring and there is room for a nyloc jam nut for added protection against the bolts coming loose.
