Ok, so I'm trying to gauge some opinions here. My rear wheels are 19x9.5 with a +20 offset. I have a set of spare 15mm spacers sitting at home that I could use. Do you think 15mm would be ok to space them out, should I do like a 5 or 10mm, or should I just leave them alone? My front wheels are 19x8 with a +40 offset and 25mm spacers just for reference.
