So I've changed my mind and decided to put US Mags on my 2014 Limited Edition R/T shaker and there are no vendors here that carry them. That said, I need to know the exact parameters, such as offset and back spacing, to order them because these will be custom forged wheels. I'm going with 18-8 front and 18-9.5 rear, know the bolt pattern is 5-115, but nothing else. Can someone here please provide me with the info I need to make this happen?
