Wheel offset

[Stingergttt]

Hi
I put winter tires on my stock staggered 19” rims. Im looking to buy aftermarket summer wheels to go with the stock Michelin 19” staggered tires that came with the car. One of the questions I get from the wheel websites are , what is the offset? Does anyone know the offset for the front and the back? Or better yet anyone have any luck purchasing aftermarket wheels for the stinger gt. Mine is a 2019 so I’m guessing the wheel specs aren’t the same as the 2018?
Thanks!!

They are identical from everything I've heard.

My TSW "Watkins" rims, put on just yesterday, are offset 40 in the front, 39 in the back; the front rims are 8.5" (half an inch wider than OEM GT rims) and the rear are 9.5" (one inch wider than OEM).
