I’m including another article by Huibert Mees. In this article he explains why lowering a car even 1” can have substantially negative effects. All things I have said for decades as well as here recently. The one thing that is not touched upon is lowering the CG without lowering the car!! What happens then? I explain this in my member's post, last Indian, a ground pounder build. The short version is there are ways to move weight & add weight all below CG. When this is done correctly this lowers the CG in a good way without impacting roll centers or suspension travel! And in doing so you may be able to move weight in such a manner like I did to affect weight distribution as well, depending on how you do it.
