Well, it's always going to ride lower in the back anyways, or at least the wheel will have less distance from the fender in the back than it would in the front. You can check out the 2003 Bimmer.info photo contest thing for pics of e34s to see what I'm talking about.
From your pics, it looks as though the right side is slightly lower than the left, but it's probably just due to the camera angle. Either way, nothing in the gallery looks visibly off. Nice color btwYour wheels look where they should be for an e34 with stock suspension.
