Happy Easter all. Sorry for ignoring this thread for a while, weeks been a bit crazy.
I had specified that only the welds on the side of the arm near and parallel to the bearing were to be ground, and that was to make sure that they cleared the subframe without binding, the production version will not have the mitered welds or any of the knuckle side welds ground.
As to price, I can say that they will be less than $600, which was my price per set at 3 sets. Until I get confirmation from the parts testers that everything works and that nothing has gone terribly wrong, ie car falls apart, I won't be bothering the machinist with premature quotes.
As to bushings, no, these won't come with bushings for the knuckle. A solution to these would be either burning out and pouring poly bushings, or you could burn out the old bushings, tear out the old liners, and use a set of trailing arm bushings cut down. I forget who did it, but someone did, probably on NECO.
And no, the end link mounting point is not reinforced beyond being thicker, I've never seen a bushing pull through the stock arm, let alone damage the steel of the it, so I don't think reinforcing it was necessary, did I miss a thread here?
