ok, what are zero rates, and what do they do? I have a 6 inch lift now, with blocks in rear and not sure about front. I wanna lower it to like 3-4 and put like 36/37's on there with my new setup. I have $2000 saved up for axles and an empty credit card with a $2000 limit that i don't wanna use... i already have bills. Anyway, heres my plans and can it be done easily... 14 bolt,4.56 or 4.88, Disc brakes, Posi (or something similar for now) Lower from 6 inch lift to as low as i can easily (no troubles) i read that lower than 4 inches and there's no stearing arm or something like that.... i have a 700r4 and np241 so the OD will help with my freeway speeds... so i think 4.88 will be better, and if i have enough i will get a d60, but what is needed with this?, here is a pic of what i hope it'll look like afterward.
