I'm looking to do an Upright Swap on my A6 for the B5S4, and the B5A4 use the same as the C5A6 on the 2.8s so ill ask the question here also. What else do i need besides the uprights? Lower control arms, axles?

Whats the reason for the swap? Early model 2000 S4's came with aluminum uprights. You'll need the matching lower rear control arm to go with the aluminum upright. Everything else is pretty much all the same. The S4 control arms have a little denser and beefier bushings to handle better.
