If you go 17x8+35, with 225/45-17 tires, you'll be flush in the front, and you'll need just a tiny bit of extra spacing out back to be flush. You could go +42 front, +35 rear and it would be more even, but at the cost of flushness, and ability to rotate tires, (different F/R fitment.)
My course of action opinion: Buy the wheels you like in the sizing mentioned above, with 225/45-17 tires, and get some 14mm OEM crash bolts. Install them in your front struts, (both holes will have the smaller 14mm crash bolts instead of a 14mm and iirc 18mm,) this will allow you to gain some camber up front which will do two things: it will pull the top of the tire in just a bit, and will make the rears look more even to the fronts, but the primary function is it will make the car handle better!
Get a proper alignment, then stand back and see how close it is to making you happy.
If you want the rears pushed out a dash more to be more even, some 3mm spacers will help a tiny bit, and are the largest spacer you can safely run on stock wheel studs. If you want them pushed out more than that, you'll have to run bolt on spacers which may be a bit too big, or purchase extended wheel studs with thicker slip on spacers.
I've learned from other people that have been patient with me, and an insatiable desire to google everything, and help people learn themselves. So it works out, and I'm happy to help.
Recap:
1) Buy 17x8 +35 Konig Oversteers with 225/45-17 (I like Bridgestone S-04's and Michelin Pilot Super Sports for summer tires.)
2) Buy OEM 14mm crash bolts.
3) Install crash bolts and wheels/tires, get alignment, ask for up-to -2 degrees of camber, and zero toe, (until you decide you want it to turn in like a bat out of hell, this will be a nice improvement, and not accelerate tire wear.)
--At this point, you should be REALLY close to how you want it--
4a) You decide the fronts are perfect, but the rears could go out a tiny bit more...buy slip on 3mm wheel spacers.
4b)You decide the rears need more than 3mm to be happy, grab the H&R slip on spacer and extended wheel stud kit in your desired thickness, MEASURE BEFORE YOU BUY! Odds are you won't have a ton of room to go out!
5) Enjoy near perfect flushness with comfortable compliant stock suspension, drastically increased grip without losing the fun 'playability' of the car, and enjoy the much improved turn in from the front camber.
Make sure to come back and update with pics, and if you get to a part where you're not sure what to do next. I love to see cars progress, and it helps others who may be in a similar circumstance and want to see what the outcome would be if they followed your path.
For a 3mm spacer I suggest these:

For a slip on spacer with extended lug kit, I suggest these:

If you go past 3mm, you need to replace the studs with longer ones to have a proper/safe amount of lug nut thread engagement. Once you go to 20mm they go from slip ons to bolt ons, which is not what you should be looking at with your wheel offset selection.
Here's what the OEM strut mount bolts look like. Your car has 1 14mm, and 1 16mm. When you replace the 16mm with a 14mm you gain movement/adjustability. You don't need a ton so OEM crash bolts from the dealer work great. If you later decide you want more, I suggest getting SPC camber bolts.
I hope that was comprehensive enough, I know I threw in spacer options and camber adjustment, but it occurred to me that adding camber will pull the fronts in, and likely make it very close to even, and very close to flush.
Any other questions, I'm here for you!
