Installed the new lug nuts today. Dealer had to break the old ones since the caps gave way. It was weird to feel how loose the caps were when I was attempting to take them off due to the flat tire I had. Once installed, you can't tell a difference between the old and new. But when off, there is a difference. These new bolts are nice that they are one piece, not a bolt and cap. I only worry about the width of the top part of the screw area, not sure what to call it. The new bolt doesn't appear to be as wide as the old. But dealership put them on and they stated they were fine on my 19" wheels.
