The worst area is the area in front of rear wheels, I still can not understand how the mud gets all over there?!?!

i held my arm out the window and down while it was raining one night, you can feel the water and dirt coming back at the car just like that picture shows..

With no mud flap, it makes complete sense to me. Let's not forget I am running wide tires and spacers. What does surprise me is that almost all of the damage was at the back. And almost nothing at the front.
