What I have found (and still confused about) is it seems the B6 (C) has been discontinued.
I found a vendor that showed the shock as the B6 comfort. A search of the part number associated with it showed "Discontinued'.
To me it looks like there is a B4 standard OEM and a B4HD. Followed by the the "Off Road" then finally the B8.
I went with the B4 standard OEM feeling I would rather be "Boaty" than stiff.
Another poster was correct in that It would be extremely rare to be doing curves at 90mph.
As far as the nose dive, I think every bushing on the car is worn so it would almost have to not be as bad as what is going on.
Thanks for the input and I will post an after action report.
