Finally, we had to take a close look at how the disc brake kit fit within 14-inch wheels. Back when we first planned this build, we figured we had no choice but to bump up the diameter of the wheels (which we still plan to do just because we want to). But to our surprise, our old 14-inch Americans had almost a half-inch of clearance. You can see it if you look really close in this photo. This may not be the case with all 14-inch wheels, but it's good knowing that certain ones will fit.
