I take it the rotor metal type option on your web order page doesn't apply since you are machining the OE rotor. Correct, for both front and back?
Also I read through your FAQ's on drilling and dimpling. Interesting that you say the soft clicking is air related. I got a set of drilled + slotted on D3 W12 from another supplier--also OE blanks underneath. There was no clicking or other obvious sound initially, but it came up over time. I thought it might be a pad issue, but finally traced it to built up dust blocking drilled holes, particularly near center. Cleaned them out with a drill bit by hand, and no more clicking. Then for the question: if you do dimpled, is it on both sides? I expect the drilling would be through/both sides. I'm assuming the slotting is on both sides if a performance element, but as FAQ's say, dimpling is more in cosmetic realm.
Finally, is slotting (or drilling) directional/by side of vehicle? I don't think I saw that mentioned explicitly or in FAQ's, but it seemed to be directional in some pics with what looked like rotors from both sides of vehicle; some other pics showed slots running one way or other/opposite too. Guessing it is directional, but then I owned a Mini R56 JCW where one direction is all they offered.
