Hey guys I've posted this question before and no one was able to help me out... I've been searching non stop and unable to find the answer I need!

I'm planning to order some aftermarket rims and I will need help with the offsets I need for a staggered set up for a 2009 g37x base coupe. I know the OEM specs but with the set up i'm planning to run I have no clue how to figure out the offset...

Rim: LEXANIŽ R-TWELVE Wheels - Black with CNC Machined Grooves Rims

8.5" 245/35/R20 Front (+24 offset?)
10" 285/30/R20 Back (+40 offset?)

Can someone please help me out! I am completely stock and still deciding to drop with either Eibach or Swift springs.

The URL above is exact same coupe as mine but a 2010 and I want to the same flush look as theirs.

They're running
20x9+32 245/35 Front
20*10.5 +42 285/30 Rears

Anyway to calculate the 0.5" difference to get the same offset as theirs? Trying not to use spacers..

No one could help before and punch the numbers into a calculator?

And for future reference tires need to be within 0.3" in my book...

And tires should be 10% over the wheel width but under 20%.

To get the same fit here goes~
8.5 +24 will sit like a 9 +30 so you'll be almost 2mm further out w/ "your" wheels compared to the coupe in that thread
10 +40 will sit like a 10.5 +46 so you'll about 4mm in from the fender w/ your wheels compared to the coupe in the thread.
If you want the exact fit you'd want a 8.5"+26 & 10"+44.
Your tire sizes are about the best combo diameter-wise for your AWD.
