how does bump and rebound control work in most coilovers?

Have megan coilover. While reading an article about suspension tuning in Dsport 33, I came to wonder how one would adjoust bump and rebound control on this megan which doesn't seem to have a seperate control for bump and rebound settings. How does bump and rebound control can be adjousted in coilover like this?

It cant in Megan's, in other coilovers there is a different adjustment. You can control stiffness and thats it reguarding the shocks. Would the stiffness be considered bump?..

The adjustability on low/mid-end coilovers controls both compression and rebound characteristics. They are not necessarily the same level at a given value.

Only certain companies make these, and they are $! hehe, i.e.

oh ok, my mistake. You CAN adjust it just at fixed values combined

How extensively will adjousting damping/rebound at same time at same(or similar rate) be effective toward countering oversteer or understeer?
Does this mean low end coilovers are only good for controlling tire contact patch over various forms of bumps on different road conditions?

the low end coilovers are not effective as far as bound and rebound control. you make changes with spring rates. low end coilovers suck. if you want some good sh*t, high end endless, tein (REs and up). Pretty much if you aren't spending above 2grand a set. You will not experience the true adjustment of what bound and rebound can do. Companies like, JRZ, Penske, Moton, DSSV, Ohlins, Sachs which allow low-speed and high-speed adjustment it what can give golden handling. BTW google "how to make a car handle"
