hmm
ok maybe what i should of said would go something like this
the initial force of one powering out of a corner shifts weight to the rear....with soft rear shocks the rear squats = more weight = more traction = less oversteer
you are right in what you say that its the rate of transfer but not correct on how this affects springs
this happens because the initial force is what decides how a car moves through a corner, the car keeps its rear down because the car is accelerating and the springs are already compressed...they dont have the ability to push back because the weight is already there and constant from acceleration and from the sudden weight transfer
with stiffer shocks...in that time frame where the weight shifts the shocks take the force and slow it...therefore the force on the springs acts over more time....with less force...therefore the car doesent squat = all the opposites of the above
thats why stiffer shocks increase oversteer...
so you are right in what you say but stiffer shocks do increase oversteer

You tool! For one thing you are talking about a completely different form of oversteer. Secondly, the equillibrium point where the spring will 'rest' during cornering in 90% of cases is totally unaffected by the shock rate (unless you course the time spent in the corner is short enough that the spring/damper system doesn't reach an equillibrium). If you don't understand why, look at the mathematical model of the situation - it will explain it reasonably well.
What is particularly wrong in your statement is when you say "the force on the spring acts over more time...with less force..." - so where the hell did the force from the acceleration of the vehicle go? The only other thing it can do is act on other springs etc - but it definitely CAN'T disappear. So the force applied to spring is definitely not altered by the damping rate. Okay some force is dissipated as heat due to friction in the shock absorber's fluid (viscosity) - but this is a VERY small amount, which is generally considered to be negligible except if the heat in the shock absorber is likely to be a reliability factor (for example the safari rally)
Stiffer shocks on bump may cause a more rapid transition to oversteer out of a corner, but causing *more* oversteer (ie greater slip angle at the rear) might only occur if the surface is particularly rough.
If you REALLY want to change the characteristics of the chassis, start with sway bars, springs, DIFFERENTIALS, torsional strength, and most of all WHEEL ALIGNMENT as the shape of the contact patch throughout the corner is quite important in changing the handling character of a car. Or alternatively we could all realise that we aren't on a race track and we could shut up.
