I limited the front end travel on my 71 Dart bracket car to 1" which helped stop a lot of lost motion, It would 60' 1.30-34 ran 6.30-6.40. I did this by using 3/4" all thread thru the bracket where the upper A arm rubber snubber mounted with nuts above and below the mount. This way it is adjustable and you can play with the amount of travel. This helped me be more consistent with my RT's On a.400 tree I think the worst habit people have is wanting to look back down the track before they leave instead of reacting to what they see on the tree.
