hmm then i would go for BCn+

spring stiffness stops the car from dipping/ body rolling on turns and stops the wheel from jumping up under the car when u hit a bump, so when u hit it u will feel it more.

dampers are designed to stop the springs from rebounding too agressively, ever see a car go over a speed bump to fast? and the car bounces? if u have hard dampers it stops the spring from jumping the car around by absorbing and controlling the rebound of the springs. Dampers wont affect how much u feel when u hit a bump they will affect the bouncyness of the ride


you could have the stiffest springs like 12kg/mm but hit a speed bump with any speed and ur car is gonna
a) take structural damage
b) be very uncomfortable
c) bounce and shake abit until all the energy of the springs have absorbed has been dessipated.

by having hard dampers the springs cant bounce back to their original shape to fast and it stops the car from jolting n that.

hope that helps
