i got a response from BC regarding why they aren't threaded all the way down
"I spoke with the development department and they said that it is designed like that because of how they mount. They didn't go into detail, so i cant give you any specifics. They said even if it were threaded all the way through it wouldn't matter because you could never use it. All cars are designed differently so all coilovers are gonna be designed for that specific application. It has been tested and this is the best design for your application."
