Just buy the Z3 fender inserts for around $30 and take it to a body shop. Several of my friends bought them and they look exactly the same.
Just trying to save the members a few$$ if they're going to buy the fenders.

 

And you might as well pick up a hood scoop and put it on the left side of the hood. OR if you don't have a sunroof, you could put it up there

 

yeah,, it's definetely RICEY for the maximas but i've seen numerous posts where members want Z3 fenders. So i figured i'd help with their budget.

i'm all about stock~

 

Hmmm... NACA duct emblazoned on the hood...

 

Um, it's going to end up costing the same. $250 for a whole fender that the shop only has to prep and paint or $30 for fiberglass inserts that the shop has to mold into the fender. If the shop is even halfway decent, they are going to charge a lot more than the $220 difference to cut the fender and then mold fiberglass pieces and smooth it out. Plus if they don't do it right, you get that really sweet looking seam around the insert.
