You are much more limited for aftermarket rotors and such with a 4.6/4.8, which seems strange.
If I were you I would go OEM as well, especially with your discount. I sometimes shop around my BMWCCA discount if I can find a dealer in my area willing to participate.
Found this on Dave Z's site;
Centric Premium rotors are identical in dimensions and internal vane design to the factory originals. During assembly, rotors are straddle cut for the most accurate machining, then double disc ground for optimum parallelism, minimal runout, and near zero thickness variation. A non-directional finish is applied for better initial pad bedding. All surfaces, including the hat, are machined and non-swept surfaces are electrostatically coated with a durable, black finish (unless noted otherwise below) for corrosion protection and good looks. Finally, all rotors are computer mill balanced to incredibly tight tolerances. You won't find a better replacement rotor anywhere
