I have (had) a little problem with my pod damping.

The lower spring for the lower disk gives so little preload to the disk so the disk just dont stay flat to the rear pod upper plate.
The upper plate have a little preload on the springa bout 0,3mm so that disk can stay flat to the pod upper plate.

Is it just me that have this problem with the lower disk that dont stays flat?

Enoway i tryed so solve this as I was driving yesterday I looked in my toolbox and found a washer that I plased on the damper post so i got a preload on the spring for the lower damper plate.

I first tough that the washer was to thick (1mm) and would give to much preload and friction to the pod damping but now the damper plate stays flat and the car feels alot more predictable and stabil when i drive.

I hope you understand me :)

ok, I haven't built or run the car.. But usually the damper plate is affected by the lube or silicone you use on the plates. So I would try say 3,000 wt silicone and see if it works well. Whatever you or your friends have thats thicker than regular shock oil. I happen to have 1k-300k for nitro touring so ask one of your friends that runs buggy or touring and they should have some.

Cheers.

It can be deceiving as well because the pod movement is so smooth on this car. I have not had the issue you have described and I used the ball diff grease from the kit for dampening.
