(raising my hand) I know the answer!
So I was hearing this clunking sound coming from the rear of the car, which started just before the rallyx school & got worse afterward. It had finally gotten so bad that it clunked almost continuously while driving down the road, just from little bumps in the pavement. Didn't do it when I pushed down on the rear of the car or rocked it side to side. So I thought that maybe it wasn't the suspension, but something else loose underneath the car. Looked all over & couldn't find anything, so I just figured I'd drive it until whatever it was fell off the car and then I'd know for sure.
Had the stock springs on at the time (which made the car pretty spongey-feeling & apparently masked the damping problem), but recently went to the ground controls with over double the spring rate. Well, now the rear was going "boing-boing-boing" after bigger bumps on the road. Definitely looks like the dampers are busted (no fluid has leaked out or anything, so they don't "look" busted). So I order new inserts to use while I send the originals off to be revalved (was planning to do that eventually anyway, because of the stiffer springs). Take them off the car, compare to the new ones and DAMN!!! are they busted. Not even close to the new ones. Oh, and the clunking is gone - so no more waiting for parts to fall off.
Moral of the story: don't take your brand-new (or any, for that matter) Konis out in a severely rutted & bumpy field and expect them to survive.
