High speed stability issues

I thank you for your input. The front end was given a drag alignment and it was there that I saw that the upper ball joints needed to be moved back. Hence the QA1 uppers. Re aligned and gained the 5 degrees advertised. Havent run it at speed yet as the rear end blew up. Super 60 now. Took a big break as I had to get the clutch,bell and seatbelts recertified over the winter. All back together now. Just trying to avoid the skating at the top end. After the stripe I drifted over the center line.....glad I was way infront of the other guy . Not good
