I am getting ready to do a brake job including rotors so now might be the best time to install studs. I think that I could benefit because I am using thin (1/4in) wheel spacers which reduce the thread engagement of the screws. Also, the screws are a PITA.

Do I need special nuts to mate to my Mahle wheels, or can I just go to my FLAPS?
Can I get studs pressed in to the rear hubs without removing them?
How do those of you who use really thick spacers mount your wheels, just long studs?

Thanks
