I don't think you're going to fit a 255mm anything in the front on stock suspension. You'll need camber plates to get to at least 2.2-ish degrees to get them to tuck in enough to run such a wide tire. A 235mm may work on stock suspension. And a 245mm may be a better match for a 8.5" rim than a 255mm - that little bit of extra width may not be worth it with your sidewall flexing and squirming.

Of the two wheel options you listed, the 17x8.5et40 would be better, maybe with a small 2-5mm spacer in front, but again...might need some camber depending on tire size.

And keep in mind this is all me bench-racing. I'm on stock wheels for now. But the 17x8.5et40 is one of the options I'm looking at depending on what Apex offers in the forged wheel they've been teasing.
