I don't know the exact diameters but 56mm sounds about right. Actually the inner foam is not soft but quite stiff. It is an entirely different type of foam, much coarser and less dense. not suitable for driving.
Again, in my opinion a good choice for qualifiers, as the car really is hooked up with these things! I normally take out some rear toe to free up the car a bit! For longer runs, they are tricky and it all depends on the track if they are usable.
