Well...just sold my RS6...but I do have a few spares that the buyer didn't want. This includes both aux radiators and all plumbing, ultimate 01e transmission that I got from DelStator (comes with new Stern motor mounts), 2 auto transmissions with torque converters, auto starter, stock TCU, and Miltek mufflers.
Let me know if you need the aux radiators or the knowledge how to bypass...it's pretty easy!
