Thanks for the response mitsuguy.
So if I go aftermarket, keep the spacers / extended studs, I'd need a similar to stock offset for my aftermarket wheels so to maintain my current stance.
If I remove the spacers then a +30 F and +35 R offset will give me the same stance.
If this is correct then my options on preowned wheels opens up quite a bit. Just have to remove the spacers and extended studs.
