s14 kouki vs s13 wheel offset difference

[Silverbullet]

Hey guys, the information that i am looking for uses terms that are too common for just about every other thread, so hopfully someone can give a straight up answer, as I know I've seen it once in a while in random threads.

I am using wheels from an S13 that were flush to go onto an S14 kouki. I would like to retain that fitment, however I know S14 bodies are wider than S13 bodies, and Kouki s14 front fender are possibly even slightly more wider than zenki fenders.

What spacers should i be using in the rear and the front? I have the impression they are about 5mm wider on each side, however I would like for that to be confirmed so proper spacers are bought

any love?
