anyone using 5mm spacers on their rear tires? if so did u have to change your studs?

depends on the wheel

everyone that's running axis speed 6 wheels are running a 5mm spacer in the back, no need for longer studs.

better question.....how much of the stud should be threaded into the lug? 1/2inch? 1/8inch?
