running a 14 > 12 stud allows 12mm lug nuts and it gives most 114.3 wheels the room needed and you're fine.
another option is to drill out the threads and press 12mm wheel studs and not bother with screw in studs
So you just take the 14mm screw in end and they go into the stock hub holes and the 12mm end allows for the use for 5X114.3. Are there variable lengths if you want to use spacers? I know there are different legnths for the regular 14mm but that's keeping it at 14 without tapering to 12mm.
