It doesn't look as though anything would rub. Thanks for any thoughts.
Max rear would be around et22 max front around et28-30 at 8”width. When I ran my stock turbines 8”wide et47 I added a 25mm spacer rear 15mm front with I think a 235/40/17. Think max spacer I’ve seen without rolling fenders and adding neg camber on the front would be 20mm front spacer 30mm rear but I think that’s playing with fire if you’re stock suspension with little adjustment, maybe pull the alignment pins on the front to help if you’re trying to go the farthest you can out. et34 extends 13mm out from where you are now so very safe on 225/45/17

Take a good ole ruler and measure from the outer on your tire to see just where you’d like to sit and plug in your info to the 1010 site linked there to calculate for your offset you’d want to hit at per your ruler measurement.
