DROOP
1. Place the car on the set-up board.
2. Push down and release the front and rear of the car so that the suspension settles.
3. Place the ruler vertically beside the chassis, so that you can see how much
distance there is between the flat surface and the bottom of the chassis.
4. Keeping the ruler in place, slowly lift the chassis at its centerline. The chassis rises
slightly until the wheels just lift from the set-up board.
5. On the ruler, note the distance to the chassis bottom. The amount that the chassis
rose before the wheels lifted is the droop value. Repeat steps 3-5 for the other
end of the car.

DROOP - ADJUSTING
When you adjust ride height you affect the droop setting. Compensate changes in ride height by making adjustments to downstops. For more
information, see “Ride Height” and “Downstops.”
· A higher downstop setting creates a smaller gap between the downstop setscrew and the chassis at rest. This smaller gap reduces the amount
that the chassis rises before the wheels lift from the ground. The result is a smaller droop value.
· A lower downstop setting creates a larger gap between the downstop setscrew and the chassis at rest. This larger gap increases the amount that
the chassis rises before the wheels lift from the ground. The result is a larger droop value.
