Looking at different options for a set of wheels for my E46 M3 and could do with a bit of help/advice on wheel fitmet if I use conversion spacers. The wheels I'm looking at for now are the Rota MXR's in 18". Sadly the widths and offset for bmw fitment 5x120 are shit so I'm wondering if I can get away with fitting conversion spacers to 5x114.3 and run a set with the better offsets offered in the Nissan fitments. Would I be able to run these specs: 11j rear ET8 + 20mm spacer (ET -12?) 9j front ET25 or ET30 + 20mm (ET5 or ET10?) Not sure if I've worked out how the offset work right Its mainly the rears I'm unsure of I know there will be some poke but don't know if it will be too much? Any help/advice appreciated
