6389 and hypertrucks

[Brently]

no different duro options atm, but what I have done is put mine on a friend’s mini lathe and removed some material at various sections to allow them to give a little more. Some info on that in my posts here:

Trampa Barrels spring position

I run barrels on the outer positions on my 12s Lacroix build. What I’ve found a little bit of success with is cutting some reliefs in the barrels on my buddy’s lathe. Still gotta throw your ass into any kinda turn as its not a carvy as inner positions. Pics on around the 15th post on this thread: Edit - to be clear if you try this do not take too much material out. I would just cut more rings rather than go deeper into the material.
