Droop is affected by both downstop setting and ride height adjustments. When you adjust ride height, you must also adjust downstops to maintain the same droop setting. - From Xray Set up book
When you use rubber tires on your car, you can set a particular downstop value to get a particular droop value, and then forget about it. Rubber tires
do not wear appreciably during use, so the droop value should not change.
