And since we are being precise to the last millimeter, the exact offset of the 20" RAM wheel is +19.04 mm, not 20 mm, which is actually an erroneous measurement anyway, since you did not indicate whether it was a positive or negative offset.
Actually it's +19.05 just looked it up on rambuilder site.
I was told +20mm on the other forum. Just never looked it up.
I think we all know its positive on the stock wheels. No car comes stock with negative offset wheels..
