Thanks,
My goal is to have the rear wheels as close as possible the lower wheel opening edge.

The stock hangers would do 1" closer compared the mancini hangers. I think with 2" (115" wheelbase) would have them touch to front edge in the lower wheel opening.

The shackles would follow the hangers and the angel of them would only change, or? I dont want them peaking directly down.

Cheers
