Pete can you post what you found so I can understand the craziness?
Nothing specifically about Auriga or this upgrades but loads of mentions of hop-up kits from BITD including carbon, titanium and aluminium stanchions - none of which worked perfectly (carbon too brittle and not smooth enough, titanium too sticky, aluminium wore too quickly without special coatings). Manitou's were the ones to do it to apparently as they didn't have liquids or gases sloshing around and were fairly simple. I was searching for a long
while with very bizarre keywords to find owt so I'll have to go through my history to find the mentions, but I know a number where on MTBR.
FirstFlight had some Ti ones posted up the other day and I know they also had some black ones on their site so he may be a good bet for a bit of info.
