The theory I have heard is that the original Spax non-adjustable shock absorbers do not rebound quickly enough after the car hits a bump. When the car hits a number of bumps close together, the rebound to standard ride height gets less and less. In certain circumstances, say hitting even more bumps one after another, the damper rod bottoms and all the shock loading is transferred to the chassis.

Hmmm... I'm no suspension expert, but I can't see how a spring would just compress more and more just because of poor rebound characteristics of a shock absorber! But I may be wrong - any examples of this behavior?
