Is the standard rear wiper not an aero? I allways assumed it was, since the front wiper are.
Now that I think about it, I wouldn't be surprised if the rear wiper isn't an aero. I have never been very happy about the rear wiper. Contrary to the front wipers (which are fantastic, the best I have have ever had on any car!) the rear wiper doesn't wipe very well. The wiper just moves the rain water&dirt back and forth instead of clearing it. I can clear the rear window better than the wiper by shouting 'boo' at it ;-)
