'90 chevy want to lower it 2" all the way around?
what is the best method of doing this?
springs in the front?
or spindles?
if I go with springs...do I need to get new shocks?

if I go with spindles do I need to remove some of the lower control arm?

I have the "Sport"..or "Super sport"wheeels on here.

and in the back it just seems I need a new shackel kit to lower it.
do I need new shocks in the rear?

do I need to do anything to the rear about the change of the pinion angle?
or it's not enough to matter?
