here is a article i found that explains a lot-
So, if one end of the car has less downtravel than the other, that end will be forced down more in a turn, which makes for more grip at that end, especially in the middle part of the turn, where weight transfer is more pronounced. Very little downtravel at the front will give a lot of steering, especially when entering a corner at high speed, or very violently. Very little downtravel at the rear will give a lot, and consistent traction throughout the turn.
But that isn't all there is to it: the amount of suspension travel also influences the car's longitudinal balance, i.e. when braking and accelerating. An end with a lot of downtravel will be able to rise a lot, so chassis pitch will be more pronounced, which in turn will provide more weight transfer. For example: if the front end has a lot of downtravel, it will rise a lot during hard acceleration, transferring a lot of weight onto the rear axle. So the car will have very little on-power steering, but a lot of rear traction. A lot of downtravel at both ends, combined with soft springs, can lead to excessive weight transfer: on-power understeer, and off-power oversteer. The cure is simple: either reduce downtravel, or use stiffer springs.
There are also some disadvantages of having very little suspension travel: the bump handling and the car's jumping ability may suffer, it will bottom out very easily.
Limiting suspension droop has another interesting effect: you can use it to reduce traction rolling. (When the car flips over because it has too much traction.) a car with less droop will have a lower CG as it turns, which is exactly what you need in an eternal struggle against traction rolls. Often it's a better solution than using stiffer springs and harder tires, it's even beter than reducing ride height or adding anti-roll bars
