It makes huge impact when it is up, makes me want to drive with the top down a lot more, and makes car more usable on highways with top down. Slight flex in upper right corner plastic (photo 5) when uninstalled, but it is rigid when installed and does not impact performance at all. Installation instruction is in last photo, you need to carefully measure where you screw in the included screws, I recommend taping the unit on to test fit prior to drilling and mark the spots. It is pretty simple install if you do not rush it. The item “Convertible Soft Top Center Wind Screen-Wind Deflector BMW OEM 2003-2008 Z4 E85″ is in sale since Monday, September 11, 2017.
