Ummm.... yeah. Unless they are significantly thick (like more than 2") or offset the camber change is going to be extremely small. I belive I only gained about a 1/10 of a degree or less from changing the control arm height about an inch and a half. RCAs are for moving the control arm back to stock to put the tie rod links in the factory position to reduce bumpsteer not for camber adjustment. If you want to play with camber buy camber plates. And moving the suspension arm position (with RCA or normal travel) will change the toe.
