On a 2015 RT SE when a large bump is hit. I installed the correct size about a month ago. I see no signs of rubbing on the inside fender/swing arms but and this part is fing weird, there are now rub marks on the inside of the rubber mud flap (this is located away from the largest radius of the tire). The noise i hear doesn’t sound like the mud flap contacting but something more harder than that. Air shock is working as per normal...baffled
