I'll try my best on the translation, here it goes according to official Mugen driver team from Spain.
REBOUND STOPS: These are the screws that prevent suspension to expand too much. For example when we pick up the car in the air the suspension arms drop and stay in a position, well, this position is the one you set with the downstops. Of course both downstops of the same axis must be perfectly equal,so the car will go straight when braking or accelerating.
Just remember that before you set up Camber and Toe, you must have the droop and car height perfectly set.
FRONT DROOP (Front Downstops or Rebound Stop)
WHAT DO YOU ACHIEVE:
By increasing front droop, you make the car easear to enter a turn, and gain steering exiting the turn.
Reducing front droop will make the car iniciate the turn faster, but will have less steering exiting the turn.
If you need more on-power steering, or middle steering, give more droop (less downstop) at the front.
REAR DROOP (Rear Downstops or Rebound Stops):
WHAT DO YOU ACHIEVE:
Increasing rear droop the car will have more lateral grip and more traction.
Reducing rear droop (more downstop), the car will have more responsive steering, but less lateral grip.
And here is another explanation from HPI's setting guide:
WHAT IS DROOP???
Down travel (or droop) is how far the suspension drops below when raised from ride height, before the tires leaves the ground. If you set a car on the ground, push it down a few times to settle the suspension, then begin to slowly pick up one end of the car, you’ll notice that the tires will stay on the ground for a little bit before they come up. This is droop.. Adjusting droop can greatly affect the way your car handles.
As you increase your front droop you will smooth the car going into the turn, and gain steering on the exit of the turn.
As you decrease your front droop your car will initiate the turn quicker but will have less steering coming out of the turn. The car will also have a more responsive feel.
For the rear, as you increase the droop your car will gain more side bite and traction.
As you decrease the rear droop, you car will become more responsive and will have less side bite, but giving you more steering.
Normally on low bite tracks such as parking lots you will find more droop will increase traction and hook your car up. On high bite tracks you will find that less droop will help keep the car flatter and increase corner speed and lap times.
If you need a little bit more steering on power, or in the middle of the turn , add a little more droop to the front suspension. If you want a little bit more rear traction in the middle of the turn, reduce the amount of droop in the front or increase the amount of droop in the rear. Rear droop should always be more than front droop.
