So I did some bodywork on the Dart recently and so happened to notice I am 'apparently' not running a snubber...
This weakens my earlier post ofcourse, but in my defence, the experience I have is based on a different car of mine which was lowered more than my Dart.

On the Dart I noticed the narrow 'boss' on the rear-axle snout had made some contact with the body occassionaly but that might very well be from bottoming out once in a while over the idiotic amount of speedbumps we have overhere.
