Nuke427:
I have been away for awhile, in the late unpleasantness in Iraq so I may be new to this fray. Here are my pennies:
1: Thank goodness you weren't hurt.
2: Sounds like State Farm is standing up, as they should
3: The missing rear bar is the probable culprit...a larger front bar
will 'loosen' the car, and a larger rear will 'tighten' it generally. Your car was probably set up WAY loose because it was dialed in for a rear bar that was absent. Another factor may have been the road surface at the point of loss, with construction going on there is no telling how fouled the road was...even if it looked clean. The
big rigs leave a lot of trash behind, not the least of which can be a lot of dust if they are hauling rocks, sediment, etc away from a work site.
4: I hope all works out well, because this hobby (and this site) could use a few more good guys like you!
Good Luck
