Thanks for all the good information. Asking questions here is one of the main reasons I come here. So much good information here given in a way that makes it easy to understand.
If I were to do this then it sounds like I would have to go with wheel spacers to keep the offset the same and I would still benefit from the weight savings. As for loading the wheel differently I really don't know what that means but the original car these
might come from has a slightly heavier (approx 100 lb) curb weight difference. That and I don't ever engage in any "spirited driving" and very rarely accelerate hard or brake hard except for children and wildlife. I drive about as boring as my life is.
