18x8+40?

To start off with, I'm new to the forum, and new to Subarus. But i am not new with "stanced" cars. Actually, i prefer aggressively stanced vehicles. not to fond of hella-flush or stretched tires. I have currently bought an 05 LGT, and it is my daily driver, i would like a nice set of rims, and a decent drop. nothing to huge, was looking for a finger gap or two (a 1.5" inch drop?). Firstly though, I'd like to get some rims and tires. I'd prefer not to pull fenders or run anything more than -2 camber when all said and done. Rolling fenders is fine though. I've been looking at these rims in specific, http://www.discounttiredirect.com/direct/findWheelDetail.do?bp=5-100&pc=51765&counter=7&wd=18&rw=8 , and would either go for nitto or falken tires, at 225/40R18, or 235/40R18.

Basically, i'm wondering if these rims would fit my criteria? and if they do, are they pushing it, or could i push the width/offset a little more?

Here's a Pic of my "aggressive" weekend/summer car.
