Firming-up dampers. What induces oversteer/understeer?

Oh learned ones with adjustable dampers, eg. Koni, Tein, KYB, etc:
Which end does one make firmer in order to induce oversteer and understeer?
I know what happens when you upgrade anti-sway bars, but after a bit of a moment up the mountains last night, I'm left scratching my head in regards to dampers.

The end of the car you stiffen up is the end you've removed grip from. So you can induce understeer on the front by stiffening the front or softening the rear. Conversely you can induce oversteer on the back by stiffening the rear or softening the front right up.
Atleast that's my understanding.

To be more accurate: stiffening shocks causes faster weight transfer during transitions, ie turn in and exit.
Faster (and therefore more) weight transfer causes less grip at that end (and more grip at the other end)
The effect is limited to transitions, steady state cornering will not be significantly effected.

by what I saw i think you should dial down the front about 1/4 turn see how that goes. You car is rock hard at the moment, more than mine I think.

Seeing as you've got coilovers you can also dial in oversteer by making the car slightly higher at the rear or lower at the front. Induce understeer by doing the opposite.
Theres numerous ways to attack the problem.

Thanks for the replies fellas.
What you guys wrote confrimed what I believe, but I asked the question anyways just in case it was completely opposite.
GP14, I've stiffened up the rears a bit and softened down the front a bit, a little less than 1/4 turn each end.
