it's going to depend on what wheel (i.e. how thick the wheel flange is)

on my stock 02 wheels 5mm was certainly NOT ok with stock studs

generally you want at least one diameter's worth of thread engagement i.e. for M12x1.25 you need 12/1.25 = 10 turns min

looked at the other way you are losing 3/1.25 ~ 2-1/2 turns or 5/1.25 ~ 4 turns with the spacers

There is a "certain amount" of thread/turns that the lug nut is supposed to grab onto in order to keep the wheels on. Putting in spacers decreases the total amount of thread/turns that the lug nut is able to grab and you will run the risk of the lugs coming loose when driving.

Good spacer kits will come with extended studs. I've been using the H&R units for my track wheels/R-comps.
