been testing over the last few weeks and two stage pistons are now available for the 811!! the team guys have settled on 27.5/25 or 25/22.5. The pistons are 8 hole 1.3mm compression and 1.4mm rebound

not that this car needs it but jumping is increased as well as agility, one the biggest difference we all noticed was its ability to stabilize after landings and of course "floating" over the rough stuff!
