While the quality of the winglet product LOOKS excellent, the box did not include any instructions for installation on my 2017 Mustang GT Performance Package with the stock splitter. The texture of the black plastic winglets is slightly different from my car’s stock black plastic splitter, which could irritate some potential buyers, but is ok for me. The video link for installation on the site is for a different model car and does not apply. One plastic rivet was preinstalled with a plastic spacer and blue tape [to secure the washer] which is a nice detail, but any test fitting of the winglet requires that either that rivet not be installed, or to push it into the wheel well, which will make locating the required ‘drilled in’ riv-nut underneath difficult to do. I am concerned that removing this revit from the winglet will damage it. I have reached out to FFP to get some insight on how the marking and the location for the drilling should be done as I am eager to get these installed on my car. One last thing, and a reason to test fit: There is the aforementioned plastic spacer at the top hole in the winglet and none in the hardware bag for the lower hole. It isn’t clear to me if that is intentional, but the spacer COULD possibly cause clearance issues for cars with oversize [diameter] tires. I am willing to travel to the Poway, CA facility for the installation if it is reasonable, and they could use my car for a video of that installation. I am a member of the Rt66 Mustang Club [see our Facebook page or website], and there are others in our club that could be interested in these and other FFP products.

These look phenomenal! I love the way they give the car a more aggressive stance. They were really easy to install. Only downside is the pushclip for the inner fender. Once you put it on, theres no removing it. I broke my bumper trying to remove it to switch out my turn signals now I’m stuck with a dangling bumper.

The surface finish is way different than the Ford texture finish. You should also add another push pin on the bottom, it does not sit flush to the splitter it hangs down with a gap about .250 inch when fully tightened. On a GT350R there is not much ground clearance.

Hey Andrew,
Thanks for the honest reply. Consider the OEM wickers are 550+, we think this is a great alternative. Do you have pictures of the said gap?

Very happy with this item and the way it looks on my car. It was actually cheaper buying from FFP than buying from the manufacturer because on the FREE shipping. Also just wanted to say that this fits well with the Drake aftermarket front chin spoiler.
