XRAY - Model racing cars

Just wondering if anyone can give me an idea of why you would lower role centres all round.

Just seen Hagbergs setup and was wondering what generally this would achieve?

Generally speaking, lower roll centers will generate more traction; conversely, higher roll centers will reduce traction... There are many other factors that can influence roll center other than the lower arm mounts themselves... I'm sure the others can offer more concise input... Hope it helps..

It will give the car more overall traction as it would want to roll more. More weight transfer, both sideways and front to back. You will loose some reaction however, as the car will change direction slower.
