I am having the RS Pro installed on my 1M later this month at the JRZ HQ in the Netherlands. They suggested 40 N/mm for the front springs and 100 N/mm for the rears and 20N/mm helpers for the dual, street/track use. If I understand correctly that translates into 4kg for the front and 10kg for the rear. That appears way softer than most unless the values for the main springs and helpers should add up, in which case I am exactly at 6 and 12 kilos. I will wait and see how this works out for me.
