Looking for opinions on rim sizes
 

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 :)

Weight matters for these cars. I would go with lightest wheels that are reasonably priced. 18 and 19 weigh more generally. If only care about looks well then pick which one you think looks nicer.

For me personally I prefer 17 on my cars if possible. 18 just adds weight and tire cost.

You should definitely check out the threads that Tcoat and BigTuna suggested. They are really helpful tools and both are threads that I used to get my fitment on my car. Mine was 18x8.5 +42 offset on 225 tires.

Imo 17s are just right. Go wider if you want more grip. 18s might get you better steering feel at the expense of ride quality, acceleration, wheel protection, and cost (I believe most 17s are cheaper than 18s). If your goal is only aesthetics, then have at it. Just be aware of what you may lose by going to a larger diameter wheel. Our cars cars are already stiff. Going to a 19 with a similar tire diameter to stock would be too rough for a daily imo.

I'd go 18". 17" seems too small, and 19" too big. This is a BRZ, not a Mercedes rolling on twenties.

"Me and my homies, so drop that
We rolling on twenties, with the top back
So much money, you can't stop that"
