Default Custom rear diffuser/apron





ha some of you will laugh and some might really like it, which will be fun to see some reactions. First we all know that parts are very difficult to find for the F without looking like every F out there so here it is.

I couldn't agree more about your last statement. I personally wouldn't do it, but you did a good job. Did you make the diffuser from scratch or hack up a pre-made one? What about a straight back shot?

looks interesting and cleanly executed. notice any difference at higher speeds? or was it totally for cosmetic reasons only? personally i wouldn't want to drill a hole into my bumper; don't really like mods i can't reverse.

The downforce from the wind isn't going to break it off right?

Also, where are you located? Auto Republic is close by.

its unique but personally I'd go for the look like everyone else route because I didn't have to put 2 holes in my bumper.
