Less you have a really hopped up car and are doing donuts down the highway. I wouldn't worry about doing a 1" or 2" shackle drop on the rear, it is really less of an issue for 90% of cars. I never noticed anything, felt more so with taking a couple leaves out. Just remember if you feel the shackles are not what you want, just change them out. It's about a 2hr job once the bushings and pins are solid. It's really been done forever. I've seen them made as long as 5" dropped in the rear.

I use the 2" drop shackles on my 36. I drive it hard for a 36 with a healthy stockish 37 flathead block and stock drivetrain.

De-arching is an option.
