Lowering a vehicle affects many aspects related to suspension geometry and aerodynamics. I am trying to understand these phenomena better. Note that although my question sounds like an opinion, it's not really my intent. I just wanted to describe how I understand things so that people can point me to the flaws in my understanding and wrong assumptions. We read in many places on the internet that one of the main reasons for lowering a car is to reduce its center of gravity with respect to the ground, thereby reducing the body roll. This sounds like a myth to me, because as you lower your vehicl

I think the easiest way to realize your initial argument of why lower the center of gravity , can easily be shown as misguided by this one simple statement. If what you are suggesting is accurate, why not create race vehicles with the Center of Gravity (CG) 10 feet in the air? The simple reason is, your side to side stability would be gone. As you lower the CG, stability is improved. Something to realize is, the CG and Roll Center (RC), while having a relationship, are two different things. By changing one, you do not necessarily change the other. Two quotes found in the book, Tune to Win by Carroll Smith (pgs 29-30): Center of Gravity: THE CENTER OF GRAVITY of any body is defined as that point about which, if the body were suspended from it, all parts of the body would be in equilibrium - i.e. without tendency to rotate. It is the three dimensional balance point of the race car. All accelerative forces acting on a body can be considered to act through the center of gravity of that bod
