Not sure what lug nuts will fit on the 2014. You can go longer and be fine. It isn't so much the size of the lug nut as it is the length of the lug stud ... because that provides the amount of bite and clamping force that will be on the tires. I wouldn't do anything crazy that will stick out past the wheel, just because I'd be paranoid of something hitting it and causing a lug stud to snap in half.
