Lower CG is not necessarily better - look at the BD7'16
You need to balance the CG with the RC and then also consider the roll sensitivity given damping and spring rates on top of the CG and RC.
It's all a bit complicated for me, so only thing I do is go by that golden rule of change one thing at a time and try it out on track.
I for sure run higher rear roll centre by using 2mm rc shims all around and run mid-high pills on the rear and stay with mid-low on the front.
