alright, im sure this has been covered a million times but, im getting a 6inch lift. Im going to get 6inch BDS springs in the front, and i was going to get 6inch springs in the back to but, i was thinking maybe i should get the shackle reverse from offroad design and then 2inch BDS springs. My question is that i dont think that the 2 inch springs would come with shims, how would i go about the angle with 6inchs of lift in back?
