Mdoc - just because a car doesnt push and isnt loose doesnt mean it has alot of corner speed. A car can have too much grip, and bog itself down in a corner.More power wont solve that, you have to get the car free through the corners.
RockDog with the arms and camberlinks parrallel the roll center would be roughly chassis level between the arms.
Lower roll center doesnt necessarily mean freeer, it can be but isnt always.
On a carpet oval, if its possible try to raise the right side roll center and lower the left side. You can do this with a slight mod to the car ( depending on the car ). Email me at email@example.com
with thetype of car and ill figure a way to do it for you.
A simplified way of getting a similar effect is to lower the camber link on the shock tower for the left side and raise it for the right side. Both front and rear.
