Man your mind is like a steel trap! You are correct. Truth be told, I have not driven the car much at all since the TOD trip years ago, and I ran the last DE on a set of 17's given to me that had a decent amount of tread on a set of Kumhos.
BTW, I am still quite envious of you owing that beautiful turbo. I dream of owning one all the time now, although I am dreaming of a 997TT with a PDK
