I have ordered (but couldn't get yet) the rear M emblem in black gloss + VO painted from IND as well, since you will be ordering the side gills, you may think about that too. You can check how it looks from the thread about the 1M that they prepared on a customer's order.
My mods (I call them minor corrections) are: Michelin Pilot Super Sports (arriving next week), gloss black BMW Performance front grill, BMW steel (not alu) pedals, IND gloss black + super light tint side gills (may change to clear originals like you) and the IND gloss black+VO hand painted M emblem (will arrive soon).
That's it. I could also have the 1M mats if I could have them here but not that important really to order internationally, maybe after the originals get old/dirty enough. The wheel paint I won't even consider unless I am totally confident with the person/company who will do this because like Aussie all I want is a slightly darker/shadow tone.
