Actually, the last time around Bilstein wanted me to send the originals back for rebuilding. They only offerred new at my insistence. The problem is they do not stock the PSS, so they had to be ordered, which took a couple months...
Bottoming seems unlikely, as I am not that low. Only about about .5" lower than the stock sport height. Bilstein never disclosed what the problem was, they only confirmed there was a problem, and they would be refunding my "core" deposit on the replacements.
