Dont know if this will help you but here it goes.
I run 20mm ichiba spacers that use longer studs to mount up.to fit my aftermarket rims.for winter i run my stock sport 20s.for me to take studs out to take spacers out to run stock is a waste of time.so i leave them in.heres pics.stock rim looks flush.i only have them in the front.cuz they are not needed for my aftermarket rims.
I personally would only use spacers thst you replace studs with.not the bolt ons
Ichiba spacers..stud replacement. Takes your old studs out and uses stronger longer studs with spacers.and hub centric fitment for prefect fitment
