OEM CR Bumper ...they did afterall say it was wind tunnel tested

 

And I said in the first post, available to the public!!

And FWIW, the CR bumper is hideous, a stock AP2 bumper with OEM lip and a large canard would essentially be the exact same, except probably lighter and obviously look better.

 

I must say, the Amuse R1 doesn't feel like it generates nearly as much downforce as it should. I would even venture to say an OEM bumper with a good splitter would work better. It sure does look cool though.

 

I would venture to say the spoon front is the most functional in many aspects.

Besides that, I think the Mugen SS is next.

 

How about C-west?

I saw on there website that they are tested in a wind tunnel like mugen...

 

Just because its wind tunnel tested doesn't mean its functional, but C-West doesn make some very functional parts.

What version bumper are you talking about?
