So in this scenario, a Ford can run a 16lb wheel with a 2lb spacer and get to the 18lb minimum. Great
However, there are no off the shelf, other than custom $$ GM 17 x 9.5 wheels that weigh any where close to 16 lbs or 18lbs with the proper spacer, Or 18lb that have the proper offset. They don't exist. Closest a GM car gets its about 21lbs with a needed spacer.
