My fronts aren't bad, I added a snap to the top Velcro to stop the door from popping open at road speeds, my rear doors on my 5 fit terrible on the rear ropes, there is roughly 1-1/2" gap.........
Ours are not that good at all. The passenger one seals better than the drivers. I haven't spent a lot of time trying to get them to seal great because the weather has been so warm. Maybe at the beginning of next winter I will try. If you haven't already bought them I would wait to see if the aftermarket comes out with something better....
I pick up my unit from the dealer when new and had to take the doors off on the road because the velcro wouldnt hold. At that time I saw the warning that they could get damaged when towing. Thought the dealer should have mentioned something as they installed them.
We tow with ours with no problems at all however we do have fabric mid section as well.we did adjust them so they fit in more then they were designed seems to seal and stay put
One other thing with soft doors "when" you lose the pull straps to open the doors use a strap from anything pretty much cut to fit heat the cut end and drill small hole through the handle wrap the strap under and bolt on the back side that way pressure is placed on handle rather then in the bolt. I got sick of loosing these and apparently you have to buy the door to replace it that's what my dealer said anyway
