After the lateral ports were installed, I began prepping the last round of parts to be painted while waiting for the previous round to be finished.
By the end of August 2021, the following parts were painted in Carbon Flash Metallic and over the next several weeks, I went to work on installing them from back to front.
ACS Rear Bumper Extensions
ACS Rear Splash Guards
ACS T4 Side Rockers
ACS Front Splash Guards
ACS T4 Front Splitter and Deflectors
ACS Side Rocker Winglets
Everything except the splash guards/deflectors and splitter were pop riveted to the body. Since I didn’t have an extra set of hands to install the Splitter, I took the front bumper back off and put some heavy duty folding tables together. I then clamped the Splitter to the bumper and stood it upright. I was then able to carefully position it to hang over the table in the spots and starting in the center, began drilling and bolting the Splitter to the bottom of the bumper.
The winglets were probably the biggest pain to install. It would have been nice to have a second pair of hands (hence to the two filter boxes shown in the one picture). But I could not get the rivet to catch enough of the factory rocket to hold it in place. I couldn't find any access inside the factory rocker, so I had to get a few washers between the winglet and the T4 rocker to allow the rivet to expand. They were officially installed on November 10, 2021.
