I wanted to be different so I installed a Vorsteiner Carbon Fiber roof with sunroof insert. I had it for about 5 months at which point I had a leak over the driver side window. I had this removed and found the reason was due to a poor install. Long story, but from that point on, I tried to stay with OE as much as possible for the items I wanted to change. A quick story on getting the roof installed was when I drove to LA to have the roof installed, when I crossed over the Grape Vine it lightly snowed on me. Granted for you folks in snowy areas you are like woos, but for CA that white, wet water stuff is a myth unless you live in the Sierras HAHA.
