New to Kia., Bought a 2021 GT1, however, not new to modding

[Donsgt1]

I picked up a Stinger GT1 last Saturday and have been busy researching what mods I want to do.
Stopped by Burger tuning website and ordered the JB4 kit with the intakes, a catch can, plugs, and the connect
Next up, I picked up ARK performance swaybar kit and Whiteline link, and GT-F springs.
The next step is wheels/tires
Here is my thought. 20x9 Variant Krypton front
20x10.5 back with
Continental extreme contact DWS 06 245/35/20 and 285/30/20 rear. How does that sound for stagger? Could I or should I go bigger in the back? Will it fit without rubbing etc?
Thanks

Congratulations and welcome! Looks good! I think @spider55 is the one that has done some wide wheels in the back

Nicely done my man. I just bought a 2021 GT1 about a month ago myself. It's a blast!

Welcome & congratulations, yes I have the wide wheels in the back.

Enjoy your car Don!

I've had my AWD GT for over a year and a half, haven't done a single thing to it. Love it the way it is.
