another thing you will want to consider is that the vents in the z3 Fenders
come so close to the edge, you may have trouble fitting the brs Fender
flares and making it look right.
And as already said, it may not look right without spacers. I don't know if you'll really like it with Fender
flares and no spacers. Maybe try photochopping it and get an idea of what it will turn out like.
