New cars...longer arms, longer links that are also flatter. They are trying to take camber gain away and lower the roll centers as much as possible to reduce traction on high bite, smoother tracks. Making modern cars easier to drive fast on today's tracks.
I'm not looking to argue the point, but it's seems black and white to me. Even at the highest roll centers our new cars probably can't get to where an RC10 was as far as HRC.
I think you have high and low roll centers backwards there. I believe the older cars had lower roll centers, resulting in more roll and higher traction on old bumpy tracks.
