Someone's asked if i know who makes this spoiler and i can't say i've seen it before..
there are a few that look like it, but none have those bumps/rivets so i'm not sure

any idea?

 

I have a question about those thing in general. What are those things suposed to do?

 

mostly cosmetic.. although a properly engineered chin spoiler (like what comes on the GT500 and the FR500) is supposed to enhance aerodynamics and downforce

 

Steeda?

 

very close, but not the same
notice how the bottom lip on the steeda is angled downwards while the one i posted is flat
also the rivets along the spoiler aren't on the steeda one

 

Looks to me like those rivets are not part of the original design and more like something that was put on afterward.



Do you have a link to where you got that picture?

EDIT BTW:
Here's a different one

 

This car is local to me and i know the owner who bought it as/is and lost track of the seller

even if the rivets were added on later... this chin is different than all those i've come across.
the one you just posted is similar, but not quite the same, especially around the edges

 

Possibly home made and the rivets where put in to hold it.. btw the one on post #4 does not angle downwards, just looks that way because of the angle the picture was taken in..

 

Yeah it looks like a rip off of the Steeda or a garage racer made spoiler.
