Good morning all. I have tried reading a bunch of threads but got my self more that confused and frustrated as there are so many different styles of setups and products. So I am hoping to get some real world experience of just making my car a little more up to date with technology and drive ability. I have bought Blazer spindles to do the brake upgrade and I am wondering how far to take the suspension refresh. 1980 Grand Prix with a swapped 5.3 NA 4L60. The car came factory with both front and rear sway bars but still has all the original rubbers. The car handles reasonably considering the age of everything. It does follow grooves in the road more than I like. This car is a summer DD and cruiser. I like the stance it has right now. So here are my questions. Firstly taller ball joints, I understand if I go with a taller lower then the car drops down a bit so I believe that I want to stay with only a taller upper. Doing taller ball joints causes the upper control arm to lay more flat so then you have to shim the lower out to get the proper camber. So secondly would it be better to change out the upper control arm and if so to what style. Because all of the rubbers are old obviously I want to replace all of them front and rear. So then the question becomes rubber or urethane or what other material. Moving to the rear as I am replacing the rubbers do I box the control arms. And anything that I missed please let me know. I won't be doing this until next winter but want to have a good handle on what I'm doing and buy parts as I go along
