I should clarify, I am not dismissing your helpful comments and tips Z or SHOdded, on the contrary it did make me stop and analyze all the driving and roads I have been on and how the car behaves! Which is why I do not feel it is a shock/strut issue.
I just know that the section of road that really made for the uncomfortable ride is one that gets ALL cars heaving about. Every car I have ever driven thru that section of I5 in downtown seattle gets moving up and down. It is elevated cement freeway with metal expansion joints, and the amount of sag between sections just gets you moving up/down. For those that boat at all it would be like cruising at max speed on a pretty flat section of water that has low very spread out rollers. About the time you settle into the bottom you are coming back up and after a few the momentum gets going and yeeeha. It truly is a crap stretch of road, and the city streets are cracked, uneven etc as well with all the drainage, and uneven settling of the ground etc.
Thankfully I rarely go up there, maybe once a year. However this is my DD and I do not want to be thinking in the back of my mind if I can go someplace or if I will have a problem with ground clearance. I also do haul around hundreds of # of pellets in my trunk a few times a week (today is 320#) I am going to give it a little bit longer though. I REALLY wish there was an airbag kit for these cars, lot of $ but it would be the golden ticket.
It helps that I will be getting my mustang back in Dec and have the green light to fully molest it into a sunny day road menace and get my lowered, hotrod fixx.
