+1 On the "Zero" Rebound.

I have been in RC for a long time, and I truely think shock rebound is something you just "cannot" do "consistantly" on all 4 shocks.... With practice you may be able to come close, but it is like trying to make lightning strick twice in the same place, you just can't do it. Then if some oil leaks out of one shock..... you just lost your handling....

The shock "spring" is the shock rebound. That is the purpose of having the springs there, and being able to change springs. Build your shock with Zero rebound and let the spring do the work. You get consistant handling, and handling you can actually change by changing the springs.

And if you don't think your shocks are reacting quick enough on a rough track, increase the number of holes in your pistons, or go to a lower weight oil. For a rough track, I like 4 large holes in my pistons, with a mid to heavy weight oil. The shocks move quick enough to respond, but are Very Smooth because of the thicker oil.
