Yes, I had seen that thread. But it doesn't mention whether anyone had added them to their cars themselves or had the dealer do it, and what all was involved in the installation. I am thinking of ordering them myself and doing it myself, which is why I asked about installation.
The only 'modification' is a small hole you have to drill in the wheel well, but don't let that scare you. The metal behind it is already drilled out, you just need to pop a hole into the plastic of the wheel well.
I'm very accident prone when it comes to installing parts but I did these with absolute ease.
