Your offsets are going to very greatly on how low you are really. As the suspension rises into the fenders it pulls the wheels in. I would recommend just looking at any and all wheel setups to get the sizing you would like. I believe rimtuck.com has quite a few different setups posted for the z. I'm personally not a fan of any of the wheels you chosen because to me they just look to new and somewhat out of place on a Z32 chassis. They are all good wheels of great quality, just my personal opinion. A set of wheels that is similar in design (multi-spoke), that does look good on the Z32 is the AME TM-02. Again, that's personal preference.
