so I picked up some brake componets today from a guy parting out his s4 T2. I wanted to make sure I got everything to run turbo 2 brakes on my car. I bought his rotors/calipers obviously as well as his brake MC, and his front hard lines.

Do I need anything else to do the swap?

 

that should do it, I did the swap and only used the calipers, so you should be fine. I would search the sight a little to see for sure. The only other thing I could tell you is, have a good friend, so you guys can bleed the system for a hot minute to get all the air out when you switch over. Good Luck!
