if i do lowering springs are camber bolts needed that way the wheels don't pitch in?

 

YES!!!

my eibach's settled and my camber angle went out the window and had to get the camber bolts after about 6k milesafter install and about ruined my brand new BFG's. go ahead and get them. then get it re-aligned after about 2-3k miles.

better to have it and not need it than to need it and not have it.

and if you have expensive tires its better to spend 100 bucks to save them then to spend 800 on two new tires after 8 or 10k miles when they should last atleast 30.
