    You are doing a fantastic job.
    The DTM needs some work indeed.....

      Hey,

      Thanks. I'm just following damper spec, so it's unlikely the DTM will be smooth over kerbs. It's just too stiff for the (lack of) downforce. The real dampers and spring have been described as being extremely stiff. I imagine the spec BMW provided is for smooth tracks and not riding kerbs. It's better if you lower the dampers and spring a little + lower the ARBs to the lower settings. 4hz is quite stiff after all. There's still a bit I can do with dampers though + stroke is a bit wrong, so it's needlessly stiff.

    Road cars are fine but the DTM becomes unstable over the curbs in a suspicious manner.

      Author's Response
      Yeah, I'm taking a look at it. Sticking to BMW damper data is unlikely to provide a truly stable result: the springs are too stiff for that anyway. But I don't have accurate damper plots, so they are open to all kinds of change.

    This is one of the best mod I have seen so far in AC. Accurate rear suspension geometry build, E30 unique characteristic and the handling has been very well simulated. My second time in my life to give 5 stars rating
