So Vargas,
Did the converting of Kilograms into pounds help with the info that you asked for, as far as comparing pounds to pounds?

While everyone has their own opinion, as to what their comfort/tolerance level is, maybe the next step would be to ride with some of the posters and see if the ride comfort in their car is close to what you find acceptable for your own car.......that will tell you if you have the same preferences, or want to go stiffer or softer.....

It will also give you an idea as to whether the handling is what you are looking for, or if you prefer something different as to over/understeer........-Bob
