IMHO, It sounds like the springs are on wrong. Most of the suspension I have dealt with puts the shorter/fatter springs on the front and the longer/smaller springs on the rear. You'll notice that the shorter springs are probably a thicker gauge (thicker material), which determines the spring rate. The length and diameter of the spring does NOT dictate spring rate, the thickness/gauge does.

You can see what I am talking about here-



Notice the shorter springs have a thicker gauge? That indicates the higher spring rate and would typicall mean they are for the front since most cars are heavier in the front.

As for this, I'd take them off and adjust the collars until the springs were free/not compressed. Then I'd measure the length of each spring to make sure the longer springs are on the rear shocks. They may have been assembled wrong.
