Not busting you personally, but your post is just a personal ego stroke.. has nothing to do with the question...

to the OP: IF (big IF) you decide on spacers... <ugh>

the standard is that the lug nut/bolt must ENGAGE 1/2 the diamater of the stud or hole its attached too... SO: If you add a 1/4" spacer... as long as the lug nut screws down more than 1/2 the length of the stud/hole its going into.... you are fine....

This is the same argument for stretching a 225 profile tire on a 10" rim to make a car "hella frush"

honestly... stupid is, as stupid does in the case of a post like this...You have made up your mind on WHAT you WANT to do... You just want someone to tell you its ok...

Rob (points might likely be pending for being to honest.)
1/2 the diameter is far too little. That's only 6mm of there's engagement on our 12mm studs. The common acceptance for a M12x1.25 stud is 8 TURNS, or 10mm of thread engagement, which is more like ~80% of the diameter.
