I just purchase a 2014 base model v6 that has wheels specs of:
17/8.5 +30mm Offset (If i'm not correct)

anyways i'm looking to buy aftermarket rims and was woundering if i could use these rims: http://www.motegiracing.com/wheels/M...Mustang%20Base

They have a +2mm offset and i don't know much about the company or how it will affect my mustang in 5 years.

 

Moved your post to the S197 appearance section - (the 2014 isn't the S550 platform)

 

a +2 offset would not work. depending on wheel width you'll need something around 30mm-45mm
