Hey guys . I just got my 2012 Audi A4 this past Saturday. I had a 2011 Audi A4 before my Mercedes and my Infiniti. I do want to change my rims and get some rotiforms. My question is what’s the lowest offset I can get?? I had +25 but I’m wondering if I would be able to fit +20 and what would be the best size tires without them being to low or rubbing. I don’t remember what rim size I had before don’t remember if all 4 were 9, 9, 9.5’s, 10 or 10.5. Please let me know what the best size would to make the fit flush. THANK YOU!!
