What offset will work

[5150medic]

2025 Mustang GT with Brembo brakes. I currently have the 19 X 9. 5 front wheels and 19 X 10 in the rear. I am wanting to go with the square setup with 20 X 10.5 front and rear. 285/35 R20 tires. Any know what the offset for the 10.5 wheels should be front and rear? Thanks in advance.

Are you trying to get them to sit flush with the fenders or sit like they do from the factory?

If you want them to sit a little more flush you should do:
Front 20/10.5 +25
Rear 20/10.5 +45
