You getting really far out of the open window to fall down! My tire shop said that too and I did ended up bringing the set back what they believed would fit "300%"! They than started to check every 18" wheel they had and only two did clear the front caliper. Period. Saying that basically every 18" would fit is not right. FYI.:cheers:Ecoboost PP comes with the same brakes as the standard GT. Basically any 18" rim will fit over the brakes. I just put a set of cheap 18s on mine for winter, they fit pretty easily.
