Went over everything after disassembly this morning and I found the culprit. It WAS hard parts contact. The bottom of the bearing spring perch and the top of the damper housing were trying to mate lol!

So I was out of travel externally, not internally I assume. There is no play that I can discern in the bearing on the spring perch or the spherical in the strut mount but I'm sure the shock load wasn't good for them...

And measured the distance from the top of the lower spring perch to bottom of the were on the damper housing - just under 4.2" . When I emailed hyperco, they said the usable stroke for these springs, 650# 7" length was like 4.4xx" - so by the numbers and lack of powered coat scuffs, coil bind was not occurring here.

So my plan is to put in the helper springs/collars which won't increase usable spring stroke or damper travel, but they WILL separate the bottom of the spring perch and top of damper by another .893" at this ride heigth. Other than that all i can think to do is add ride heigth.

I'll call MCS and vorshalg on Monday and pick their brains if i get a chance at work. A HUGE THANKS to everyone for their info and discussion here! Joe V
