I have a set of new 30 mm front RCA's made in Japan. These are quality RCA's made of steel and will give you from -6 to -9 degrees of camber (with stock adjustment) in the front for that aggressive look. Studio does not make them anymore, so these are your best bet. They are brand new, have not been installed in my car b/c I am going with a different wheel setup. I paid almost $600 for them. Your loss my gain. Shipping in U.S. only.
Asking Price: $450 shipped OBO.
