since we are adding to a wishlist:
In the Miata world there is "shorty bumpers" that cut inches off the length of the car. im not sure what kind of room we have, but anything that can slim the look of the Z could be cool ( fenders bumpers hood ect ).
check out what RyanWest did
Got a little creative!
a flat bumper cover could look good
On another note, i am in the group of people who want a non plastic intake manifold and a cost effective solution to the weak oil pump stopping the car from higher revs
