I've posted this sentiment a few times, but here goes: front-only looks unbalanced to me. Like half-finished or --at the risk of offending--half-a**ed. And it neglects care for the vehicles behind you.
In my experience, the Bronco isn't throwing rocks on-road. The mud flaps/splash guards are to protect the Bronco from the debris being thrown up while off-roading. Having done a few off-road excursions prior to getting the splash guards, I found ample evidence of where the splash zone was, and the portion aft of the rear tires was essentially unaffected. After putting on the front guards, the amount of mud and debris on the Bronco was all but eliminated.
As for the half-assed look, that was one reason why I chose the OEM splash guards. The blend in well, and with their three-dimensional form molding, they actually look like they were intended to be there. People really don't even notice them, let alone that there are front flaps and not rear flaps. I personally think the flat rubber flaps that look like cut-down semi-truck mud flaps are hideous.
