Hi all. I need an advise in wheel offsets for MB. I have an opportunity to purchase a set of OEM AMG wheels off a 2002 S430 and I would like see if these would fit my 1990 SL. I think the offset for these wheels are 42 but my OEM offset is 25. Im not very well versed in this area and a little confused. So, would a wheel with 25 offset stick out more than a 42 offset? If I really want to fit a 42 offset wheel, would I then have to add a 17 mm spacer to achieve the same fitment as a 25? Likewise, would a 35 mm wheel offset need a 10 mm spacer to achieve the 25 mm fitment. I apologize for the elementary questions but as I said, I am not too familiar in this area. Thanks in advance.
