The K-Mac adjustable camber plates (front) and the poly eccentric bushings rear are a "son of a bitch"(rear) to put on! For you DIY ers out there I would just assume send it to Australia and have these guys who came up with it do it for me if I had to do it all over again. Fronts are no problem, but 2 full days of cursing, banging, bleeding on the rear and "I can't take no more". Finally finished up though, and need to get it alligned. If anybody needs info on how I solved some of these problems, I'll be happy to let you know.
