Question Torn between 2 rim widths..

I have a 2010 wrx (Stock suspension) and am looking at wedssports sa15r 5x100 18x8.5 48et or a 5x100 18x9.5 48et (same sa15r just wider) wheel. For the 18x8.5 go to 235/35-240/35 tires and I believe (prob wrong) 255/35-265/35 tire for the 18x9.5.. correct me if I am wrong. I spent months trying to decide what wheel to get, this being due to the fact I feel the 2010 wrx got screwed on fitment options... I plan on coils, sway, bushings, etc etc. For now its a DD but I will track after college. My question is what is the best choice of Wheel/Tire size of my two options here for the best increase in handling over current stock wheels/tires set up?

I am Very new to the tire fitment thing, and suspension geometry (I know wider tires doesn't mean better handling, keep around 25" tire + wheel height, etc.). I spent a good amount of time doing some reading and this is the last thing I need cleared up. So any feed back is greatly appreciated. I am also not afraid of fender work. Thank you for your time in reading this post and possibly replies.

18x9.5 the 2010 Wrx body can fit it easy. I am on 18x9.5 rpf1 +38 on a 07. The offset is close to stock so you shouldn't have rubbing issues.

...says the guy with a different body style car.

Check out the 2008-2010 WRX fitment thread. I think you'll find that generally people have a hard time fitting larger than 245 width tires without a lot of work. Given that limitation, I'd stick to the 8.5" wheel. You COULD run the wider wheel with the skinnier tire, but it would weigh more and give you performance benefit compared to the narrower wheel with the same tire.

Thank you guys. Good point Mach V, I agree, especially when I want to lower the car in the future. The link will prove useful as well, I couldn't find it under a general google search and well obviously couldn't navigate the forum well enough either. Much appreciated gents.

Not remotely close to anything stock in really any capacity. It holds a tire that's about it.
