Thank you much and I'm sorry for the delayed response. I don't check in often as life gets in the way. I have the taller tires on now (have had for months) and I'm still at stock ride height. No rubbing and no issues at all. The hub centric rings are all you need at least with a 20x9. Any wider idk if you'd need spacers. The Pony wheels should fit great with only the hub centric rings and will look great. I went with an aftermarket center cap that says FORD to ditch the Mustang emblem and look factory.I have wondered if Mustang rims would work on our vehicles. So other than the hubcentric rings you didn't need spacers? Car looks great dude! Would love some Pony rims on mine
