RE: OFFICIAL Detta ST THREAD **********
I do agree that your st hexes may need a little more off-set, but I'm sure you'll figure something out with more testing. I've been using atomic kmi adapters from time to time, and they are a nice touch since you can use them on both the buggy and st.
As for the delrin shock tower idea, I'm a little unsure about the idea. The amount of flex would worry me. A lot of us just double the towers for more strength. What about making some out of steel or 3mm alum? Shock towers sound interesting, but I'd really like to see some delrin arms for st and pbs buggy (upper & lower), rear hubs, or extended 12mm hexes. Those are things I would buy since comparable parts in alloy make the truck too heavy imo.
