Hi guys I have a ford focus 2016 with 18" after market rims and 20mm spacers. I rolled the fenders and have no problem with rubbing (unless I turn and go through a dip or bump) when I'm by myself or with a front passenger, but when I have someone in the back the tires rub on every bump. The tires I have are 215/45/18. I have no trouble when people are in the front seat unless I'm turning but that's rare. Everytimr anyone is in the back though it rubs and I'm not sure what I should do. I thought of getting new stiffer springs like God speed, but all of them lower the car so I don't see this being a good idea. I'm not sure though what are your guys opinions?
