Hi! I am new to the outback familly. I want to change my mags & i was wondering if an offset of 48 would fit on my 2012 2.5 premium outback. If I am not mistaken the 17" that came with my car have an offset of 45". The rims I am looking at are the motegi mr119 in 17" it comes in 40 & 48 offset. Or should i go with the 40 offset & put spacer i am not so sure. Sorry for my English not my 1st language. Thanks so much.
