Yeah your right enough, I thought the rear sat funny too, I thought camber would make it look better until I realised how much hassle it is to camber rears on micras 
even thought pulling the arches wouldnt exactly fix that look!
I really wanted to go lower too but I was getting my discs and pads done at my mates garage yesterday when i was at work and my car got beached on the ramp..
So bolts may sort of fix the arch gap I have too haha
