I run 17" 8.5J fronts with offset 50. Works really well with 225/45 tires, as the stretch prevents flex in the sidewalls.
I also have a set of so-called Cup2 17" with 8J fronts - offset 52.
...and simply look at the offsets of the OEM 18" 8J fronts for guidance - the wheel diameter doesn't matter when you are considering the offsets that work.

I guess I'll probably use these Eibach 15mm spacers, effectively converting the 70ET wheels to a 55 ET position on the car, the same as the original 7" wheels.

If you have the part number on those I would appreciate it.
My 17x8 ET70 ebay wheels came, and they're fine, but I'd much rather find a pair of ET52 ones so I wouldn't have to use a spacer on the front, which requires converting to longer studs, etc.

I have these wheels and will post pictures of them.
I've been running 225-45-17 on the front of my NB C4 on the oem 7" wheels, but recent testing by GRM and Tire Rack clearly shows that running wider tires on narrower-than-optimal rims actually hurts performance, so I'd be better of just running 205-50-17 like normal people.
But then I got the idea to upgrade my front wheels to 8x17. I couldn't find the oem 993.362.126.00Cup 2 8x17 wheels with 52mm offset (except buying new for $1300 each), but found a pair of 993.362.126.01Cup 2 8x17 with 70 mm offset. (I think maybe those are 928 rear snow wheels, not 100% sure.)
Then I bought some very nice H&R 21mm spacers, which would "correct" the 70mm offset to 49mm, only 6mm (about 1/4") further out than the 55mm offset of the stock 7" wheels.
I test mounted a bare wheel on my car yesterday, and it looked......bizarre.
The spokes of those wheels arc outward significantly. I had hoped the setup would look stock but more aggressive, but instead I think it looks just weird- the spokes extend beyond the fender.
So..... I'll either just go ahead and mount my new PS AS4 225/45 on the oem too-narrow stock wheels, or I will more likely return those tires and just get the standard 205/50 size like a normal person.
As you were.
