Car Bounces after 60 ft. What is causing this??

I don't think the front end needs to be loosened. I think when he is coming up on the foot break the front end has already lost its travel because he has extended to much. I bet if he took his brake distribution valve off and put a proportioning valve on, moved his brake bias to the bigger rear tires say 70 /30 to keep the front settled more off the foot break he could rotate his weight better. At the end of the day until the car can keep the rear tire loaded it will keep doing what its doing. In my novice opinion the shock and leafs in the rear are the issue not the front.
