I have the Cravenspeed door bushing on my 2017 MX-5. I never have problems with the door not closing as some others have reported. In this video I let gravity close the door. At about 12 inches, the door won't close. Up that to 14 inches and it does.
It takes way more than 14 inches for me to climb in my car so, even if I don't give the door a pull (which I always do), the door still closes completely.
