True most of the time. As traction comes up ride height should go down. This is usually to prevent traction roll. Roll is controlled by pivot blocks and camber links. In VTA I run low blocks (this keeps the chassis flatter) and long camber lengths (this makes the camber change slower-rolls move). It might sound counter productive but it works. I look at like this, the block set the starting point and the camber link lengths are the adjustment. I would start with the camber links are parallel to dogbones/universals
