I am trying to change my diffuser. Does anyone know how to do it?
The screw that is on it is different from thr other DIY

 

you mean the two sides? THey are rivet and you have to drill them out.

 

Yep it's rivet. Just drill a little it will get loose. The rest of the diffuser is clipped. Good luck!

 

cant see it too clearly but that is the spot connected to the bracket right? you can actually take the bracket off with the diffuser no need to mess with the rivets

then you can either fabricate brackets (i will show you mine tomorrow at the meet) or you can go get long bolts like some members suggested

 

that looks like the torx screw on the side of the bumper.

hmm, at least on my car it was a torx screw. That does look like a rivet though.

 

That is definitely a torx screw, it should be easy to remove with the right torx screwdriver. I also unbolted the whole bracket attached to the diffuser, i didn't bother drilling the rivets out. I used longer bolts for the new diffuser instead.
