Not the bottom ball joint. It really depends how old your suspension is, but my G27 S4 and G20 bottom ball joints were the same. Top ball joint is different on the G27 (or it was until very late on in the S4 run when it also changed to top adjustable wishbones)
G27 racecars with the Sierra hub/upright and G20's use a balljoint from a Saab 900 , doesn't last too long as on a Saab it just locates the bottom of the strut and doesn't have to take the spring loading , cheap enough from GSF.
I didn't know they were the same as the G20, you learn something new every day. I did think they were from a Saab, just didn't know which one. Thanks for the help.
