SPC Upper Contorl Arms Setup
I purchased a set of SPC adjustable control arms, but I'm having some difficulty setting them up. They come with spacers to help maintain proper axis of rotation, but I can't figure out if they're supposed to be used in conjunction with the spacers/washers used on the stock upper control arms. If I leave the original ones off, the new arms bind on the knuckle, but, if I put them on, the arm sits way to far outboard and the nuts barely fit on the bolts. If you try to adjust the arm geometry when leaving the original spacers off, you run out of extension before the arm sits right. Is there something I'm missing here?
