The RS lowering spring set in the car catalogue (ie Microcat) has some plates included. These are not available now, from what I can see. I think these were to pos the camber back a bit when the car was lowered. It may be possible to make something.
I havent seen them, but adjustable TCA arms can be obtained, far as I understand.
You either have to move the top of the strut out, or shorten the TCA.
