Hello all, def searched but was unable to answer what I'm sure is a simple question from any wheel dudes. 07 GS 350 - lowered 1.75 in front and 2 in the rear, stock rims w/ 20mm spacers. Keeping my stock rims for winter tires and will be buying new wheels. My question is. I am going to keep my stock size and get 18*8.5 rims my question is if I wanted the offset to match my wheel with spacers currently what offset would my new rims require? I would like to remove my spacers and have the new rims have a similar profile but from the rims own offset. So basically what rim offset would match my stock give spoked with 20mm spacers? Do I just keep spacers and order wheels with matching stock offset? Any input appreciated here's my car for reference

 

18x8.5 offset +25

 

Awesome thank you!
