It's happening. We are just under way with what we believe to be the build of 2013. We are going to be converting a 2013 B8.5 S4 to a RS4. We will only be using OEM parts on this build and remain as true as to what reality would look like if Audi were to ever grace us with a RS4 sedan for the B8 Chassis. We will be documenting the build on our blog as well as Audizine so make sure to subscribe over there and stay tuned for the progress photos. It will be epic.
