    no 90/10 on the rear end, just put a 7/2, 8/0 or 9/3 on the lr behind and your troubles will go away. More compression will stop it from slamming down and keep the car on the bars longer

      3c/6r on the 5th coil.
      5c/0r on front of LR birdcage
      Double adjustable behind the LR birdcage and anywhere from 6c/4r to 7c/2r depending on track conditions.
      Works for us.
      No matter how hard you try to keep the car up, there will be times that you have to dump it and the nature of the rear steer in a 4-bar car is going to make the car turn right (relative to where you were steered anyway). The driver will have to learn to anticipate when this is going to happen to some extent. There's no way to completely get rid of it unless you take all of the rear steer out of your car...I don't think you want to do that

        Reporting back results :

        Adding that 90/10 on top of the rear end (damper) appears to have fixed the car.

        Settles down nice and predictable / consistent when I have to unload the throttle now.

        Thanks for all the suggestions.

          I'm wondering, how did you get a 7" stroke, 90/10 shock on the front of the cage and have enough travel?

            Added a 2" extension rod-end-eye thing on it.

            Like this, but without the adjuster :

              Yep, that's what I got on a 9" shock on the LR front!
