You're in luck then. Since you want non racer looking wheels, you have options. Off the top of my head, here are a couple.
First off, not many people know this, but Imex makes a 17mm wheel. Check em out!

You're also in luck, because HPI, the kings of style when it comes to wheels... Has just released the warlock wheel. These are 17mm as well. If these arent cool enough, then i just cant help ya. lol
These come in many colors, but of course... Black is best!
Judging by your pics, you'll need the ofna extended axles for these wheels. I believe your wheel setup is wide offset. The Imex should be perfect though. Also Ofna makes the dominator wheels which look nice too.
