Guy's I already have 30mm RCA's. I am thinking of getting negative RCA's made. Sort of like the pic. I know when you lower the car or have Coilover (check) the mac pherson struts will create neg camber (and toe). Installing RCA will take out camber and if the RCA is the same height as the car is lowered, you will be back to factory camber and factory RC.
I want negative camber RCA as I plan on running 2 deg of negative camber all the time. I know I can do it with my strut tops, but by using neg roll centers it will be easier and the strut tops will not have to be as wildly set to make the camber.
