No matter if you do this yourself or buy some high-buck aftermarket control arms, you end up at the same place, with altered roll center. Like I said, this may be something you can live with, maybe not. But I certainly would do a little cuttin' and welding for myself before I would shell out bucks for someone else to do it. The aftermarket arms may be a little nicer to look at, but whether you do it or pay someone else to do it, you end up at the same place.

If you pay attention, you can make the arms look good and anyone looking that close is looking for trouble.

If I were to do this, I might even be tempted to make a 1" aluminum spacer to fit between the upper arm and the ball joint to angle the arm up a little for increased camber gain on bump. The whole thing is gonna be screwed up anyway, so you may as well experiment while you're at it. You could take the spacer out if you didn't like it. The whole idea is to keep the tread of the tire flat on the ground in turns and usually a little more camber gain will help.
