A Microsoft update ruined the computer that has my primary batch of suspension programs and I am too lazy/involved to calculate by hand at the moment. However, I can tell you that the Sector rates, while roughly the correct front/rear balance, are a soft track setup but a bit on the stiff side for the street (I have several thousand miles on that setup). The other two set ups you mention are in the neighborhood of medium street, very soft track setup, but if you were to drive either on concrete slab surface roads you likely will notice a bothersome/uncomfortable ride motion as the front/rear ratio is too high. If you want to do a little research on this search on Maurice Olley (Olley ratio).
