AI75-I am not sure.
superfly-is this only when you are at full lock on your steering? If so then it is just the cvd's that is causing all the racket.
RCGary-Try raising the roll center blocks .020" and then run the 4F block in the high roll center holes. That should hook up the rear end more. Also use 55 pistons in the front and 54 in the rear. That is very important on carpet with rubber tires. The bigger hole piston gives you more grip.
proracer3-You sound like you nailed it on the head with the oil/piston. I run Magenta or Tan rears and Cyan fronts from TRC. I always run mine on top of the servo. You can try on top of the tunnel.
