Pff, you people are drunk. Those flaps are awesome, I love how they make my car look I think they look even better on his car due to them matching his wheels and blacked out emblems. +1 for a clean car.
Mine does, it's gonna happen regardless, but mine looks 10x better than before mud flaps. I blame the +48 offset on my wheels for that look since the stockers weren't as bad.
It actually got dirty BEFORE I put the flaps on It hasn't really gotten much worse since then, and it's pouring rain out today so all that mud (thank god the salt is pretty much gone) is just rinsing off. Woot.
