Thanks for replying to that. I have a 1/10 scale buggy im learning to tune on. i have spent some time reading this thread. I have found it informative, but trying to apply it and understand the results is taking time. This subject kinda came up with a friend of mine when i mentioned moving a ballstud. He was very postive that if we moved ball stud up one hole on tower that it would stiffen the suspension in its up and down travel.
