When I first got my smart I didn't like the way the wind off 18 wheelers or spring storms blew me around. I searched the Canadian site since they have had smarts for years and found some threads that said that Airtabs helped a little in combating this. For such a low cost I figured why not. So I bought 9 at about $3 each. Put six across the rear of the top above the rear window and the remaining three under the front end on the splash pan.what purpose do the airtabs serve and any pics installed or writeups?
