    For your car it's a long way to instability. You

      Lenghting the wheelbase has only a small effect.
As long as you don't get too short you'll be fine.

   So that's what that little point on the roof was,

I'd try to move the break point back some for lower
drag. Also with that much glass area The heat from the
