They are a piece of cake to adjust (Great Design). You will only need a set Allen wrenched and some standard wrenches. I did have to adjust my camber; not sure if my spindle is a little bent or my frame. The quicksand a-arms allowed me to adjust until the camber was set. (I will be looking into the problem with the bend later).
Problems: Because I did adjust my camber out a little on the left side (About a half inch) I ended up bending the hemi joint threads a little (By the way, anyone know where I can get a new one?).
Also, Gary is a busy guy; he only does this in his spare time (I believe). He told me he would have the part to me in two weeks and it took over 60 days. I can certainly understand the delay, but the part I had a problem with is his communication, he would not return my phone or e-mail messages. He did get back to me via PM 2 times during that 2 month, but only to tell me that I would see them on a certain day, which would come and go without delivery.
Bottom line for me; I think he makes a great product, but the customer service (communication) was lacking.
