17x8 TorqThrust II - what offset is 4.75?

I am 99% sure that 8 mm is the correct offset for a 17x8 (to get to 4.75 inches of backspace), but everyone wants to sell me -11mm or 0 offset (tirerack doesn't even list the 8 mm offset wheel when I search by vehicle). To make it even more confusing for me, I have a set of TT II's that have 11 stamped on them, but it isn't -11 and it doesn't say offset - it's just on the back of the wheel (and the backspacing is 4.75 when I measure it).

Can someone tell me what they offset they have on their car?

Any help is appreciated - I'm about to go bonkers from people looking at me funny!

Thanks - I did see that chart, but wanted to confirm. The TT II doesn't come in 6, so it looks like it's 8 for me...

The offset of 8mm results in a B/S of 4.810". This is .06" of B/S more than the 4.75" measurement and also 1.52mm more positive offset
