Offset on new wheels

I’m buying some 17" wheels this week and I am curious what the proper offset is. My car is lowered 2.5" and the tire should just tuck inside the lip. Do I need a different offset or will I get the right size just by telling them what kind of car I have. Any help is appreciated.

The proper offset is 35~40mm and the lug nut spacing is 100mm

Will it effect your lowered hight? I don’t know, mine is only 1" lowered.
