cab,
the springs will not be long enough when the suspension is fully extended. The "Hyperco" springs installed on my Pantera are secured to the upper spring retainer of the Koni shocks with cable ties. When the car is jacked up, the other end of the spring is inches away from the other spring seat, so the spring is loose as you describe. Once resting on the ground, the springs are not "loose" or free to rattle around.
your friend on the PIBB, George
