I have a 2006 S430 and with few exception, really like the car. I want to replace the stock steel wheels with some cool mags from a 2002 E55. The wheels are nearly identical except the E55 have a 37mm offset. I'm not sure if it is a positive or negative offset. I believe if it's positive the wheels will not clear the calipers and if negative, there might be rubbing against the fenders. Does anyone have any answers? Thanks.
