HELP: E90 LCI Offsets with 9.5" Rears

All - Your help would be greatly appreciated. I'm looking to buy some used wheels, but don't know what the proper offset is, especially for the rears on my 2009 LCI E90. From reading I have seen different/conflicting information. Don't want to roll my fenders.

What I know:
Rear track is 8mm wider per side than non-LCI E90.
I've seen fitment recommendation from ET35-ET45 with 9.5" rears.
I've seen pics of people running 9.5" ET35 w/ 265's and 10" ET38 with unknown tires, and they seem to fit, but I don't know if they rolled.

Bottom line, I'd like to get a setup like this, but I don't think the ET33 with 275 rears will work... http://www.e90post.com/forums/showthread.php?t=690869

Will they fit, and if not, what is the right size? I can't seem to find a definitie answer on the boards, so hopefully this thread can help somebody else out, too.

I just sold my '09 e90 LCI with 9.5 et33 rears with 275/30/19 tires. They rubbed slightly until I rolled the fenders. So somewhere in that area is going to be your limit. 265 tires and/or tires with rounded edges will allow a more aggressive offset without rolling...

Every wheel and tire package is going to fit differently. In other words some wheel manufacturer's et35 might fit more like another manufacturer's et33 and vice versa. Same holds true for tires. Some tires have a more rounded edge and are not nearly as wide as another manufacturer's tire. Take for example Michelin's PSS, their 265/30 series tire fits more like a 275 from another manufacturer.

All that being said, I am lowered and I ran 19"x9.5" wheel w/265/30 Conti DWS tire et35 offset and there was plenty of room, no roll. In fact I added a 5mm spacer effectively running an et30 offset and there was still room. No rubbing or rolling required, BUT that's with my tire/wheel package.

Now I am at et25 w/10mm spacer with a slight roll and loving the more flush look.
