So your front is spot on with Ultimates figures
I'd guesstimate that the back is up at least 70mm, probably more like 75 to 80mm.
Those rear springs are definitely not right. Too much arch. Look too stiff, and and look too long. They shouldn't be too long unless they are the wrong part for your vehicle, but it sure looks like they are.
If you can stack cans of water or bags of cement or stuff like that on one side of the tub to compress and flatten the spring, you will see if the shackle is going to be able to swing rearward enough to accommodate the spring length, or if it is going to lock up.
You need to identify the springs. If they are not too long, you can then decide whether or not to modify the EFS springs, or to modify your stockies. If the EFS are too long, modifying them will not be practicable
Either way, you were right thinking that it was sitting bum high, and getting it down a bit (but not level) would be a good move.
