rear susp. problems

[leafpave]

I installed my susp. tech. springs and KYB GR-2 struts today. The fronts are fine, but the rears are the problem. The spring flops around inside the strut. It moves about 1/4 to 1/2 inches up and down. I installed it in the car and it seems to be fine but I want to know if its a common thing. It doesnt move when installed in the car. Please Help.
Thanks
P.S.-The springs are 1" lower than stock

never mind since knowone replies I think I go it figured out. My only problem now is fixing the golf ball size hail damage that just trashed the car. Great huh.
