David... One thing to consider when choosing your camber plate is the compatability with the shocks you will be using. I origionally had Carrerra shocks and camber plates. When I switched to Bilstiens I found that the end of the strut that goes through the camber plate bearing was a smaller diameter. I had to have some spacers made.

Of the choices you listed I like the Ground Control. It looks like a very good piece from a well known company.
