Hope somebody has an idea. I’ve owned numerous cars and SUVs. My 2019 Crosstrek is driving me crazy. I drive down a dirt road or a road that’s been salted and it’s dried....and the rear end of the car is pure filth. I mean covered like Ive done a week long dirt rally. Now, the front end...spotless, sides, barely but the rear end....I can use all my washer fluid just by going down one dirt road. I have the oem mudflaps but I’m wondering if anyone else has tried to reduce the turbulence causing this mess. Slots in the wing help? Bigger mudflaps? Full width flap? It’s like, I’m driving...the cars looking good but who the heck covered the rear end in dirt? Thanks for any help.
