1.) Make sure chassis is flat using Hudy droop blocks on a flat pit board.
2.) Set ride height
3.) Set droop using how many mm up travel I prefer for track
4.) Use a tweak station just for piece of mind (but if car is flat on blocks and makes ride height with all shock collars even, 99% of time, it's right)

1) Check chassis tweak by using hudy droop blocks
2) Set up droop
3) Set Ride Height
4) Set Camber
5) Check droop, height and camber again

1) Check for physical tweak in the chassis
2) Choose mounting points for shocks/links/steering etc.
3) Ride height must come first, everything else follows
4) Droop
5) Caster
6) Camber
7) Toe

All affect one another to a greater or lesser extent, so recheck (and maybe recheck again) once set.

I personally do Droop first using gauges, even if I have my shocks mounted, long as you know what your ride height is going to be you can do this.
(if you want 2mm up travel in the rear and you know you are setting your ride height to 5mm, then set it so the tires just lift at 7mm)

I figure do droop first, because if you have suspension issue or your shock lengths are different, your droop will be off when the suspension(shocks) are attached.

So I do:
1)droop with gauges suspension off(mainly just to make them even)
2) ride height
3) actually set the droop using the "up travel" method with shocks attached
4) recheck ride height(setting droop sometimes changes ride height)
5) camber or toe can go next I do camber
6) toe
7) check ride height and droop again

I rebuilt my stuff 100% from the ground up after each run so checking tweak and stuff is a given with my set-up. After the car has been built:

1)Ride height with actual tires I will be running
2)Hudy Set-up station (camber, castor, toe)
3)Ride height again (as camber can effect ride height)
4)If any changes were made to ride height, I use the Hudy set-up station again just to double check everything
5)Uptravel

No sure I like this as everything (and I mean everything) is based off of the diameter of the tires. You cannot assume that because it reads 5mm on a droop guage that the ride height will actually be 5mm with the tires on the car.

With rubber tires you may be able to get away with this and be close or somewhere in the ball park as rubber tires will for the most part always be the same diameter, but with foams this is 100% not the way to do it!!

Note: From the XRAY world, it is assumed that the fixed caster blocks are already mounted and the rear toe is set

1) Check for physical chassis tweak using droop blocks under each axle
2) Set ride height with tires (if foams, they are trued evenly first)
3) Set initial droop (rise over ride height) evenly between front and rear tire pairs
NOTE: steps 4 & 5 are only done once after a major chassis/suspension change or new weight distribution on the chassis
4) Reset downstops evenly on droop blocks - I use the right rear and left front tires (both on your right as that end of the car is facing you) as my baseline from step 3 above and adjust the left rear and right front tire to match them on the droop blocks
5) Check for spring tweak and adjust spring collars - using alum setup wheels and hobby knife centered under each end of the car method
6) Camber - changing camber always effects toe more noticeably than the other way around
7) Front toe
8) Repeat steps 2 & 3 again in that order, to account for any small changes in the tires contact patch from adjusting camber

How can you set the droop propperly before the ride height?.....................
How much droop is related to the ride height in the car.............

downstops are downstops regardless of if suspension is on or not right?

Like on the RDX you have set screws that will only allow the arms to go down so far, regardless if the suspension is on or not.

You are right how much droop is related though to the ride height of the car.
I'm not recommending you do it this way, but if you know your ride height is going to be 5mm, then with the wheels on the car, adjust it so the wheels just come off the setup board at 7mm, to give 2mm of uptravel.

How do you know what your ride height is unless you measure the ride height first?

You don't, but you know what you are going to set it to right? Typically around 5mm for a carpet/rubber setup.
Why I like to set droop first is because at least on my car with a rubber setup, I get in a situation if I set the ride height first, then my droop, my droop signifigantly changes my ride height. So I try to get my droop in the ball park first. Adjust my ride height, then fine tune my droop.

I`m still having a hard time understanding how your droop would effect your height when set properly. Droop when set properly would never effect height !

I`ve been seting cars up for a lot of years and always set ride height first, then camber , then droop .........I think you will find that , that is why everyone is having a hard time understanding your set up directions , they have always heard of people doing it always set ride height first, then camber , then droop
