I need the offsets for the RX300 and GS400 (17-inch factory). Where do you get those numbers?

Out of curiosity, why? The offset for the rim won't help you in determining a replacement (aftermarket non-replica), Each rim style will have its own requirement/spec. for what the proper fitament with respect to offset. Spoke/dish style, as well as any lip will contribute to a varying in offsets by wheel as an example my O.Z. wheels have a +44mm offset, but there are others who have used Racing Harts that are +41 and others who do the Supra TT brake upgrade that got to +38 on the GS.

Sorry I don't have an answer for you, it might be better if you gave a little more info around the question.

Thanks for the info and I think I understand what you're saying. It's just that when I buy new wheels, I would like to keep the offsets as close as possible to the original. Too radical a change in offsets have been known to cause premature bearing wear and that was my experience.
