The Dunlop Elite 2 sidecar tyre made system turn much better. It turned out to be narrower than the 3.25 (i think) tyre it replaced. 

And from the side 

So, here is what it looks like with the new windshield. Pretty good, in my opinion! The whole bike/sidecar setup looks lighter and more balanced than with the high original windshield. For touring I can still attach the detachable wshld to bike. This gives some wind noice so I have not ben using it so much.
