I was looking around and was looking for an inexpensive adjustable rear camber arm kit for my Model S. I came across a company called JeePerf. They make a kit that is reasonably priced. Has anybody ever heard of them? They give a Lifetime warranty on their machined metal parts. 1 year on the PU bushings. 6 months warranty on the Heim joints which they supply. Feedback would be greatly appreciated. Website is JeePerf.com
