19x8.5 +35 & 19x9.5+35 Fitment Question S Coupe

Hey guys, I have a 2009 G37S coupe and I was looking into a set of wheels that were 19x8.5 +35 & 19x9.5+35. I’m currently dropped on coilovers as depicted in the pictures. I have the staggered 19” sport wheels with 225/40/19 in the front with 25 mm spacers and 275/35/19 in the rear with 20 mm spacers. If I get these wheels will I have a similar stance? Is it likely that I will rub if I use the same tires and spacers? Or will I need to get smaller spacers? I’ve already shaved the rear bumper tab completely. Thank you in advanced!

So doing some quick calculations, the stock sport wheels are 19/8.5+43 and rear are 19/9+45. So with your 25mm, and 20mm spacers, that should make them 19/8.5+18 and 19/9+25. Not including tires in the calculations, but with the same spacers the front wheels you would have .31 in more clearance on the inside and the face would be pushed out .31 inches. With the rear wheels you would have .14 in more clearance on the inside and the face would be pushed out .63 inches. Camber and how stretched the tire are also influence fit, I would think with the same tires on the rear it would sit a little lower than it does now due to the increased stretch. That's about as helpful as I can be as I have limited knowledge. Also, love the lights! Here's the offset calculator I used https://www.fitmentindustries.com/ti...et-calculators
