I think the 12mm spacers will look perfect. I have m3 reps and Im using 10mm spacers with no problems at all. Ive had the 10mm on my oem wheels for a while too. no problems at all and they sit perfectly.the m3 reps are et35 in the rear yielding an et of 25 with the spacers. no rubbing, no vibrations.
