Can someone verify my google-fu is correct please?

The GT/CS wheels are the same as the V6PP wheels in that they are both 19 x 8.5 with 50mm offset. Is that correct?

Since the stock wheels are arguably (depending on who you talk to) too narrow for a 275 tire I'm considering taking the plunge on these:

If the 50mm offset on the stockers is correct, then these at 35mm offset with a 275 tire provide the same clearance to the suspension as stock and only protrude outward a bit more.

verification of the offset is appreciated.
