My rear springs are the 12" 95lb ones so maybe my shock absorbers are the reason for the hard suspension. Maybe I should invest in some TTR adjustable ones. I do find that I have to screw the spring perches up to a fairly high position to get a normal ride height and I guess this will have some affect on stiffening the suspension. I will check that my front shocks are on the minimum setting though.
under normal setting conditions (e.g. not coil bound...) changing body height would not change suspension stiffness.
The perceived stiffness results of 2 factors that are combined in operation : amplitude of motion for a given stimulus (coming from spring stiffness, typically expressed in lb/foot) and dampening (coming from the shock, which may be adjustable). It should be noted that the front ARB is also a spring of sort (responding to a differential stimulus from side to side), and the aeon limiters as well when they come into play (end of travel).
stock springs are 75 front 67.5 rear
then open to debate, fast road in the region of 150-175 front 100-125 rear
and race can go quite higher (300 and up ) depending on the track...
Shocks set very high would make the car feel stiff, regardless of spring values, as they would prevent any fast large body motion with respect to the wheel (no motion = no suspension) : if unsure of the setting, you may want to check the shocks adjustment, or reset them to the recommended value, and possibly experiment different settings, before changing parts.
