The bolt is stuck and i dont know how to remove it

Yikes, I was in this position not too long ago on my S3 upgrading to adjustable camber bars, is the bolt itself stuck, or can you unscrew it slowly to extract it? If you can get the bolt out, what you need to do is use a screwdriver to adjust/move the rose joint on the hub carrier straight. Once you've done that, try and see if everything lines up without putting the bolt through. Once you are happy, now this is the tricky part, you need push against the brake disc face for it to line up and put the bolt right through before rosejoint moves to the position like in the pic.
