Thanks for the imput.
Anyway, I now have an extra chassis that I can devote to making a rally car.
what I have come up with for the shocks is this, use the long shock shafts front and rear, run the adjusment all the way down to raise the ride height, and use 30 wt oil.
Next problem is protecting the internals from rocks and dust, as well as the motor.
I'll keep you all posted, and if you have any ideas, please feel free to post them.
