Briefly, to "get an edge" you need to accomplish three things: 1) you want to reduce the weight (the lighter the better); because all of the weight transferred is so-called "sprung weight" -- chassis, engine & transmission, driver, etc.), and then balance the total weight of the car among the four corners; 2) you want to get your roll centers low; (yes, it is possible to get roll centers too low) and 3)you want to optimize body roll -- in the sense that you want to deliver force on your tires where it can be translated forward, rather than sideways momentum. It's literally a matter of "getting a grip."
