I don't know this for sure but back when teams raced the z32's I think most went with the 2+2 due to it being more stable. Personally I like the look of the 2 seater version but the 2+2 isn't a bad looking car. I had a 87 300zx as my first car & I thought the 2+2 in that version was butt ugly. I have a 94 2seater tt beater that has had a tt swap & it is plenty stable. I'm not racing so take that for what it's worth.
