So the car just hit about 1,500 miles and I've added clear side markers and the TRD lip spoiler.
Installation of the side markers is pretty simple. Using a flat head screwdriver just find the tab located in the middle behind the marker and they pop right off. Then it's just a simple swap and they snap back into place.
The lip spoiler was also pretty easy to install. It did not come with double sided tape as advertised, but I bought some and applied it to the underside. There was a pretty clear outline/indent for where the tape is supposed to go, I just followed it all away around the underside. For additional security I drilled to holes in the spoiler to match the mounting points for the OEM wing and secured the new wing with the OEM screws.
