well when we got to the rears they won't fit like we put the top bolt on and like the spring is too short so the spring kinda flops around like its not sealed like the fronts.

is this usual.?

 

Is this when it's jacked up? If so, that's normal. I have several inches in my rear between the spring and the perch when I jack the car off the ground. Put the car on the ground slowly and make sure everything seats properly and you're good to go.

 

What kind of shock? If its a stock length (from the bottom of the top hat to the lower perch) they will probably seem short in full droop (car jacked up).

I had them on the Neuspeed variation of the Koni Sports with the 5 lower perch settings (wasn't using coilover sleeves at the time). Had to use the highest 2 of the perch settings to keep the assembly snug. If it was on the middle perch notch (stock setting) it will be loose in full droop.
