I remember seeing something about Dinan parts being sold through some BMW dealers in CA and I know that they offer a warranty to match the factory warranty, so Dinan is generally considered the factory-friendly option.
I would expect most of the mods for the N54 to be applicable to the Sdrive35i as well. Obviously thinks like suspension and brakes may be different, but I think the 335i gives a good indication of what can be directly used or what could be available shortly for the new Z4.
E90Post is a good place to look for mod information. Apparently the dealers are not liking SW mods, but many of the piggy-back systems are working hard to make them undetectable to the OBD.
