Here is a 5th gen with a rear diffuser:

 

nice work duesy keep it up

 

Found a pic of this which would work:



Would look better if it was body-colored

Or this one from a 2005 Mustang Shelby Cobra 500


This could be cut and bolted on to our lower bumper. Dealers wants $553. YIKES!!!!

 

yes body color. i want that one too. where can we buy?

 

That top one was on ebay a while ago. Not sure where to get it. I'm looking.

 

Still trying to figure out something that will work that is cheap to make or buy. Any ideas?

 

Here is what I have so far. Just wanted to know what you think. Its upside down and the fins nearest the camera will curve around bottom of rear bumper



The shield will block air from getting behind rear bumper, hopefully reducing drag and increasing gas mileage. The fins guise the air to smooth turbulence, thus increase grip. thats the theory anyway.

 

looks good duesy keep it up and post more pics

 

Here is teaser pic: I got one fin on. I will work it so it fits a bit better.



I have the other 3 fins done. Just need to mount them.

 

awesome job man. where did you get the parts?

 

made them. Ill post details in new thread when its done
