I know very little about this car, but from what I can tell it has been taken very well of. Any insight would be appreciated. Thanks.

Welcome to the forum, ThisGuyTaylor .........
No, it's not normal ...... leastwise not with my all stock (cept for the muffler) 2013 FR-S.
Those are pretty big tires for that car ...... could it be the tires making the hmmmm .. ?? I suggest you try upping the tire pressure a couple of pounds to see if it goes away. Maybe rotating them to see if that helps.
Do I read that right that the exhaust is all stock .. ?? That would be unusual for a pre-owned FR-S. You might check and make sure all the exhaust connections/hangars are secure.
