E90 320i 18 Inch Non Staggered Rims

[delrosa81]

I am looking to downsize from 19inch staggered rims to 18inch non staggered rims. 19inch staggered tyres are very expensive to me, I compared the prices for 18inch non staggered tyres and found its way cheaper.

I have decided on 18 inch Advan RS rims but I'm not sure on the rim width and offset for a flush look.

Anyone have got any idea or experience on Advan RS rims?

I tried googling but didnt have much info though.

Thanks in advance
