Absolutely no issues on the highway, with or without uppers.How do half doors do on the highway? Considering some for this summer for cruising and whatever with the soft top down. But running no doors (I live a number of miles from town) on gravel roads/highway was dang windy. Windows down was fine, but somehow the tub must create an air vacuum down low. Also the lil nub on the full doors looks weird without a top on.
There are some times where they absolutely suck for daily use. Like when it's raining and you need to unzip a soft upper window.. to go through a drive thru.
