Hi John, so by raising the roll center of a car whether it may be in the front or rear will generally add traction to the side where it is raised? I am quite confused with the roll center thingy. Some say that when you raise the roll center, it will lessen traction on that end, I am I correct? The reason why I am asking is because I tried raising the rear roll center of my car (RDX) to add more steering because I was informed and read in the manual that i will give the car more steering because it will will lessen traction on that end but will feel stable. Is there a difference between stability and plain traction? I hope you can shed some light on the differences, Thank you very much for your time
