Cog spacer..?

hello guys! i am trying to sort out my chainline, i have a sugino BB 103mm but the chain still touches the outer side of the teeth of the chainring... Is it really bad if i put spacers on the hub..? i hope it will not need more than 2.5 mm but i am worried if there will be not very much thread for the cog and the lockring..

No problem putting spacers on the rear hub. Standard BB spacers fit, but if you dont have any laying around velosolo sell packs. 2.5mm might be your absolute max though. Just make sure you can get a few good turns of both.
