If you are happy with 17s with good Michelin tyres I'd be inclined to stick with them.
But you could always try those 108s to see how they feel before you get involved in refurbing them, although if they have run-flats it won't be an equal comparison.

They're the Brembo 4 pots from a Megane RS (the mod quite a few on the forum have now done).
It was a challenge to find a set of 17" wheels that fit over them. I contacted Apex about it as I originally wanted a 17" set of SM-10 or ARC-8, but neither of them would fit (other than the non-concave version which I didn't want). They convinced me that the VS-5RS would fit in 17" with a concave design (17x9 ET30), but they were just too expensive to justify.
In the end I went with Bimmerworld TA5R (17x8.5 ET38 front and 17x9 ET42 rear) from across the pond, which fit nicely over the Brembos.
I can tell you my opinion.
I thought about various 18" wheels, but then you get 255 tyre width in the rear. From what I've read, you will just introduce more understeer. Also, at least for my 2.2 with 170hp I don't think that I need a wider tyre to put power down. I also believe 18" is a heavier wheel so again, worse performance (not that I would notice that but I like efficient things haha).
Only pros I have seen with 18" are looks. Maybe if you have 3.0i or supercharged one it makes sense to run 255 because you need to put the power down.
I also don't like to risk rubbing the tyre so I have only looked at OEM ones for E85/6. I believe BMW engineers knew what they were doing. Aftermarket wheels have some stupid offsets from what I've seen from various manufacturers. Everyone says there is no rubbing but then you introduce your car to Misha Charoudin and you can hear stuff.
After all the research, I will just be lowering my car a bit and putting some bilsteins, while keeping my 225 style 105 wheels for a livelier back end.
After all, it all depends on what you want. Every direction you choose is fine.

I looked at style 189 from E90/2 but I have read on the other forum that on M sport suspension there is some rubbing. May not be true, who knows with what people are doing to their cars
et34 at the front doesn’t usually cause problems, even on M-Sport.futureZ4buyer said:I looked at style 189 from E90/2 but I have read on the other forum that on M sport suspension there is some rubbing. May not be true, who knows with what people are doing to their cars
It was suggested that old shock allow some movement that causes the wheel to rub. It doesn't rub on top of the wheel arch, it rubs at "10 o'clock" if you look at the left wheel. There is some weird shape of the cover, it sticks out for some reason.
Other people with spacers or lower ET wheels have no problems on their cars with OE M suspension. So there has to be some problem that causes mine to rub.
