Don't worry about the rating on these wheels, you don't want to use them. Your stock wheels should be 16x7 with a 12mm offset. These Mustang wheels you're looking at are 17x8 with a 45mm offset which means that even though they're one inch wider, they will go in farther than your stock wheels. In way too far. It'll make your track narrower than stock and worsen stability. If you decide to get them, you'll need to use at lease a 1.5" thick spacer/adapter, maybe even a 2" to get the wheels out to the fender edges. Hope this info helps.
