Alright so I found some Kyb Agx shocks for 347 shipped.If I got those do you think I would need to change my drop springs?I'm not sure how long they have been on there.I know they are the yellow nuespeed sport ones.2.5 front 2.0 back.But right now how it sits the back seems lower do you think the springs could be sagging or would the kyb's fix the rough ride and even out the drop they way it should be?
