1 correct 2 correct (will do that during SVA) 3 I doubt that it'll be an issue, Zs are made in the same factory for the whole world 4 again, this was only proved by a very early JDM model over only one dyno session, so imo this is debatable 5 all Z in the world have now the same suspension setup as the European ones (since Nov 2004 IIRC) 6 yes, look for ST models (or why not models or colours only available in japan) 7 true in most cases
more importantly, JDM cars are normally limited to 112mph
