Picked up the spoiler today and did a quick mockup.

Haven't quite figured out yet what would be the best way to mount it, but the size is very close to the car. Maybe 2-3" too wide at the most outer top edges. But since the material is flexible and can be bend inwards a bit, I don't think this will pose any problems.

Hardest part will probably be how to neatly incorporate the spoiler with the valance and lower fender on the sides.
Perhaps cutting off the upright 'flaps' to the height of the center of the spoiler will give more possibilities.


Here are some pics...
