Heres a picture of my 72, 2.5 drop spindles with 2inch lowering springs in front 4inch lowering springs in back.I know not a good picture. Also a picture of my buddies 71 red and white with the same drop.... I had this same drop on my 71 and rarely had any problems with Speed Bumps and that was with Long tube headers.......It's Not like we plan on speeding through the bumps any how..
