George,

Adding a spacer to the top of the spring is not good practice. It will cause all of the ill effects I mentioned.

If you space the top of the spring down yet do not move the jounce bumper down as well, than your spring can compress to a length that is shorther than it was designed to compress to. If this occurs you run the risk of overstressing the spring as well as coil contact. Coil contact could lead to the coating being damaged which could lead to corrosion which could lead to failure.

When you encounter a pothole, the jounce bumper is the primary source of force that stops the wheel's upward motion. If you do not move the jounce bumper down than the wheel will stop at about the same vertical position.

If you move the spring down and not the jounce bumper you the wheel will still stop at about the same vertical position that it would have before you added the spacer, but the spring will be compressed more at that point than it would have been had you not spaced it down.

The stress in a spring is proportional to how much you compress it. If you compress it more than it was designed to it will have more stress than it was designed to.

It would be much better to space the jounce bumper as well as the spring. This way you may only have the reduced rebound travel issue from the short extended length dampers, but you will not overstress the spring. You will incresae lods into the body if the overall travel is reduced. Due to short extended length dampers. (which is not always the case)
