This is interesting calculator if you want to compare rims backspace/offset and see impact on how wheel sits in your wheel opening. I compared a 2L Fuchs 4 bolt with ET40 to the EMPI Fuchs replica with ET45. Ok would have to redrill/replace rotors/drums to 5 lug bolt pattern but I would gain and added 5mm/.20" to the spacing to the outer wheel well lip (which I have already sanded). I can probably sell my 4 2L Fuchs for what going to the fake polished Empi Fuchs.
