Finally, upgraded to the 20mm rear sway bar. I have to say, after 3.5 years of rain, snow, and road salt, the threads on the endlinks did not fare well. Trying to get the nut off the link ended up stripping out the Allen key socket. Definitely recommend removing the endlinks with the RSB attached, then removing the RSB. Had to use vice grips to get the nut off. Looks like upgraded endlinks are next on the list for me. I can 100% feel a difference with the stiffer RSB. I took a 200 mi trip, and noticed the back of the vehicle does not wonder as much as it used to.
I also added a L7 license plate delete to cover the holes in the front bumper, since I moved my license plate with the custom plate relocate bracket to the passenger side.
