Mine looks the same way.... i also just removed my entire stereo which was quite heavy.
I love the flat low look and do not at all have any desire for a rake like your pic. I'm running the stock end links at the moment. i do have the SCP shorter one's in the tool box but have no idea how I put them on.... anyone wanna tell me. I can then let you know if it makes a difference. I'm just reworking the stereo and gonna put it all back in and then the car will be nice and flat once more. must've raised the ass end a full inch.
on a side note your front end looks very low almost like it needs some work.
