I'm going to install a Tyrol Sport SSK pretty soon. I want to change my shift **** as well to a TWM product. I see they sell an adapter for the MINI (unthreaded-threaded):

Will the shift boot connect to the adapter?
Will the adapter add any height to the stifter stick at all?

I ask about the height because I want to get TWM's competition shift **** but I am unsure if the 10" option will be too much if the threaded adapter adds some additional height by itself:
