What specific car are you trying to tune?

It would be a lot easier to start with a baseline setup for your given track condition and then make minor tuning changes from there. To get rid of "traction roll" there is a really nice chart provided by Hudy which shows you the priority of changes you should make... once you've maxed out a given option for your car, then go down to the next item in the list until you get the car working as desired.

Keep in mind that there is always a give and take.... for example tuning out traction roll tends to take away steering so you might discover that the car can't make as tight as turns as it used to, but with the benefit of not traction rolling.
