Are you wondering what droop does?

Another factor of learning rc car suspension tuning is knowing how droop can affect handling.

Droop, as defined by Webster's Dictionary is "to sink, hang or bend down or to lose vitality or to become dejected".

But in the world of rc cars and trucks it means something else entirely. For us it referrers to the amount of down travel or travel above ride height our suspension has.

In learning about rc car suspension tuning droop is another of the key elements of getting your suspension perform just the way you want.

Having your droop set correctly will help you over those bumps, ruts, holes, uneven spots, through corners, braking and acceleration.

Droop's main objective is to help with weight transfer like sway bars. While sway bars only transfer weight from one tire to the opposite tire relative to the amount of load on a given tire. This weight transfer is only left to right or right to left not front to rear.

While droop aids with weight transfer from front to rear and vice versa to maximize traction over the rough stuff and with on-power and off-power steering. With droop having an effect on side to side and end to end weight transfer, it has more of a 360° effect.

But droop is still important on off-road vehicles.

The thing to remember about droop on an off-road vehicle is when you are setting ride height.

If you set your ride height too high, you maybe alright on jumps, but you could be hurting performance through ruts, holes and other rough stuff.

Getting droop set correctly on an on-road car is more critical.

It plays an important role in maintaining maximum traction on acceleration, cornering both on-power and off-power, and chassis roll.



As a general rule the effect of different droop settings is relative same for both on-road and off-road rc vehicles.

Net effect of less front droop:
1. Reduces front chassis upward travel on acceleration.
2. Improves high speed steering ability.
3. Increases on-throttle understeer.
4. Better on high speed smooth tracks.

Net effect of more front droop:
1. Increases front chassis upward travel on acceleration.
2. Reduces high speed steering ability.
3. Reduces on-throttle understeer.
4. Better on tracks that are rough with ruts, bumps, holes and jumps.

Net effect of less rear droop.
1. Reduces rear chassis upward travel under braking or off-throttle.
2. Improves stability under braking.
3. Better on high speed smooth tracks.

Net effect of more rear droop.
1. Increases rear chassis upward travel under braking or off-throttle.
2. Improves steering in slow corners.
3. Better on tracks that are rough with ruts, bumps, holes and jumps.





A reference guide for different droop settings.
1. Need to reduce off-throttle steering - Reduce rear droop.
2. Need to improve off-throttle steering - Increase rear droop.
3. Need to reduce on-throttle steering - Increase front droop.
4. Need to improve on-throttle steering - Reduce front droop.

Are you running on a smooth, high-bite track - Reduce droop on all four corners. - Keep your rc vehicle flatter.

Are you running on a bumpy, loose track - Increase droop on all four corners. - Let your rc vehicle roll more.
