Just wondering how many of you all have mud flaps on your cars? If so, do you have the OEM Kia ones? I have read that they help with snow building up in the wheel wells. What do you all think of that? How hard is it to install the rear mud flaps? I found a video for the front, and they look really easy. Last, what did you all pay for them? Would love to hear your thoughts. Are they worth it or not? I live in the midwest, so I do get quite a bit of snow. I'm just debating if it's worth to spend money on it or not, and whether it will truly help keep the building up down in my wheel wells. Thanks much!
