18 x 10 on all 4...Help!

I am wanting to order (4) 18x10 TT2's with the chrome centers & reverse lip. I cannot get a straight answer on what offset and backspace I will need. I have seen a few people on here running 18x10 all the way, but they don't reply with what offset/backspace they are running. I'm not confident enough in the measurements I take myself.

Does anyone have the chrome center TT2's anyway? Please post some pics if you do.

Also, if no one knows the offset/backspace for the 18x10 up front, do you know the offset/backspace for 18x8 up front for a reverse lip?

Thank you!!!

if it's very close to +50mm offset, you'll be perfectly fine.
