Any improvement in MPG since you installed it?

Unfortunately I'm unable to know for sure. I've made a few changes to my car since installed (SD, FIC 2150, stripped rear interior) so I don't have a base to compare to. I can say I am getting better mileage since I've done the diffuser, but it may be a combination of things. My main goal for this was the stiffen up the rear bumper so it doesn't flap around like it did before, and it did its job. The rear bumper is solid now even when exerting force directly where there used to be flimsy spots.

Guys this looks great. Well done! Kind of makes me want another 2g. Although I think shipping costs would kill it.
You want a cheaper aluminum, get it in a 5052 and get a 4x8 sheet. How big is the largest piece?
If you guys need anything more complex cut or not I can cut it on the plasma cnc table.

Looks amazing and I'm glad it's finally been done. Start selling them cause you have a customer here as soon as I could get my hands on one!

Looks good man. I agree with attempting to mount it a cleaner way but does look pretty damn nice. If you do go into production with it, would there be any choice on how large the strakes are per order?
