The carbon fiber pillars are holding up just fine. The reason I installed them is because I wanted to tie all the carbon fiber together from the front splitter and grill to the cf side marker lights to the mirrors to the rear spoiler and diffuser. If you have other cf components it will look great. I also had shadowline trim. I bought them from Bimmian.com.
