Just watched your video. Sticks are the best. I think you could benefit from taking some clutch out of it. I can hear it pull the engine way down on the hit and it's beating the tire up pretty good.

You can take some of the hit out with chassis and shock adjustment as well, but the clutch hitting the tire like that is usually too aggressive of a clutch tune.

What flywheel are you using and what's the gear ratios?
