Downstop setting (measured with blocks) = difference in height between chassis, and bottom of wishbone. This can be looked at as the entire down travel of the arm.
Droop (measured with a ruler or ride height gauge) = difference in chassis height between static ride height, and tires lifting the ground.
Here is a real world example of why it's a good idea to not confuse the two. Lets say you set the following: (all made up numbers)
ride height at 5mm
downstops at 4 (using the blocks, tires off, shocks off)
Now, lets say that with this setting you end up with 3mm of droop, which is what you are after... great. Now, lets say you later decide to change your ride height from 5mm, to 6mm. Without even touching the downstop blocks, you have changed your droop from 3mm, to 2mm, reducing weight shift.
So you can have MULTIPLE droop values, for ONE setting on the droop/downstop blocks, since droop is a
result of the downstop settings
AND ride height, put together. So while related, droop and downstops are two different things, and they are commonly confused and interchanged with one another.
But I digress.
