Believe it or not - the open space between the wing and the base of the tailgate/hatch is exactly the same viewing space you have out of the rear anyway. Amuse have done a great job keeeping it in line with the original rear view.... So there is no blind spot or hinderance with the rear view at all....
I can't see why people complain about the rear view from the Zee.. It's a sports car with a sleek sports car look - how good do you expect the view to be and how can you expect to make it any bigger, taking into account the shape of the rear end.... Once you get used to the overall size of the car you should be able to tell where all four corners are anyway.... All the Zee's from the 240z up have very similar rear views...!!
Sure! He's out in Long Island. I don't plan that many performance mods. Just exhaust, test pipes, reflash and some cosmetic stuff. Not going to crazy with it. Where are you located?
