can you post a pic. showing the top view. And congrats on your initiative.

 

it would have looked nicer if you didnt bend teh sides up as much

 

Do you do spoliers for the Z?
That looks ok if it was not bent up so much, it just doesn't look finish, may be if it had a straight line on top of the two wing sticking up.....it might look like the STI spoiler but not as dramatic.

 

I like it because it's different. It's not extreme but it is noticable. Good job!
