Hello, As title says I am looking to see how big I can go on rim size on a stock body 2013 BRZ. I found 18s that I want that are perfect visually to me but I am wondering if I can go 19? If so what type of measurements would I need to look for? The ones I have been looking at are Konig Dekagrams in matte black. Any type of help is much appreciated! I want a noticeable difference in size and feel like the stock 17 to 18 wont be as dramatic. Thank you
