RTR Undertray Extension (24+ Mustang, All)

Easy install and gives the under body a finished look.

Under tray extension

If you get the splitter you definitely will need this to add rigidity. The push pins they give with the tray don’t fit . They are to small . Luckily I had some that were the correct size . Other than that it’s way easier to put on than the splitter . Took about 1hr from start to finish.

Def gives a more finished look (under the car)

I was a bit disappointed with this products fitment and hardware compared to the rocker splitter, chin splitter, and rear quarter panel splitters. The product does tie in the chin splitter to the OEM undertray belly pan. However the included Christmas tree push pins are undersized and wouldn't hold the middle portions. The holes didn't seem to line up with the OEM screw locations on the edges near the tire which was a huge fight to get the screw to line up to the OEM U-clip. I ordered more christmas tree push pins from Amazon. However this could be a one off experience (2024 GT Performance Pack)
