Thank you for a very clear, concise, well-written explanation to the subject at hand! kudo's. Very good chart which should come in handy for alot of VX'ers! (myself included!)
What prompted me to post (earlier) was the implication that some of the posted offset info was wrong (possibly mine being one of them.) So I spoke up mainly to draw attention to the fact that I knew my info (+12mm) was correct.
The backspacing info I gave (4.5") was in error (actually 5"); but, hopefully I covered my butt with the ole IIRC
Here is the wheel specs for my particular wheel for demo: (#614-6883)
(Part Number) - Size - Offset - Backspacing - (Bolt Circle)
(614-7882) - 17x8 - 0 - 4 1/2 - (8x6 1/2)
(614-7875) - 17x8 - 12 - 5 - (5x5 1/2)
(614-7870) - 17x8 - 12 - 4 1/2 - (8x170mm)
(614-7838) - 17x8 - 12 - 5 - (6x5 1/2)
(614-6882) - 16x8 - 0 - 4 1/2 - (8x6 1/2)
(614-6870) - 16x8 - 0 - 4 1/2 - (8x170mm)
(614-6885) - 16x8 - 0 - 4 1/2 - (5x5 1/2)
(614-6883) - 16x8 - 12 - 5 - (6x5 1/2)
(614-6873) - 16x8 - 12 - 5 - (5x5)
(614-6838) - 16x8 - 12 - 5 - (5x5 1/2)
(614-6835) - 16x8 - 0 - 4 1/2 - (5x135mm)
(614-5873) - 15x8 - (-19) - 3 3/4 - (5x5)
(614-5865) - 15x8 - (-19) - 3 3/4 - (5x4 1/2)

Also, just an FYI for newbie wheel shoppers; check out hub (bore) dimensions(diameter) before buying as this has burned previous VX'ers in the past! (I do not recall the actual dimension for our hubs.)
