I have stock dimension non adjustable tubular upper control arms on a 72 GM a body. I want to run tall upper ball joints. Can I run .9 or will I run into geometry issues? Should I just stick with .5 on stock geometry arms? I don't want to run the tall lowers because I don't want the car any lower to the ground. This is a street driven car I am looking to improve the handling characteristics on.
They only had a .5 when I bought mine a few years ago. I'm using the Proforged like this one from Jegs: http://www.jegs.com/i/Proforged/469/101-10016/10002/-1?parentProductId=2001760#moreDetails They work exceptionally well and I have no issues with my non-adjustable tubular control arms. What part number are you looking at for your .9 long studs?
Both proforged at summit...they now make a .5 and a .9. The .9 are pn 10017 at summit Also knuckle busted, did I understand correctly from another post on this subject that you tried the straight upper arms like these from sc&c and did not like them? http://scandc.com/new/node/57 If true, what did you not like about them? I am also considering going with these arms and the .9 ball joints. Ok....never mind.......I found your post on the straight uppers.....so you are now running stock dimension tubular a with .5 tall ball joints? If so, how do you like the set up? .5 is enough to get a noticable improvement? That is exactly what I am considering as 1 option.
