Cool, nice writeup...damn thorough haha.

So did you just leave them the stock control arm length? Are you going to just have it adjusted when you get an alignment, or mess with it to check tire clearance, etc before your alignment? I'd mainly be interested in finding out if you have more tire clearance at the same camber setting with the Ingalls vs SPC. In theory I would think you would, because instead of the SPC pushing the top out, the Ingalls pulls the bottom in.

What was your camber setting at your last alignment? With my rear camber right on the spec limit, I have minor rubbing, but no biggie.
