thanks
If you ask Alexander Hagberg, he will tell you to rebuild your shocks before every race, and I do the same. Aside from your oil being black, I've never experienced this as I rebuild my shocks often (oil, bladders and o-rings)...
Shock Rebound: You will get more consistency with zero rebound. Basically by having rebound, the piston/oil isn't helping restrain the spring which will give the car a bouncy feel. Most of your top pro drivers run at zero rebound and will aide in a more consistent shock package at all 4 corners. If the shock shaft is pushing out by a mm, this is still considered a dead shock (zero rebound).
