Has anyone done the 1" Upper A-Arm drop modification (Shelby Drop) on their 64-70 Mustangs? While primarily a road racing thing, there are supposed to be some benefits in lessening the positive camber gain on the launch and wheelstand. I have spoken to a few guys and they seem to be split on whether there is a benefit to doing it.. I am trying to keep the wheels straighter on launch, as now the tops of the tires lean in. How did this modification effect your alignment?
Any thoughts?
