I then did each end individually with the front and the rear again while observing recoil.

After observing all recoil with collars 100% out and noting my results I then, still with no shock fluid, tightened down the shock collars on all shocks approximately 12 threads and conducted the same tests.

From a height of 8 inches (same as before with no collar adjustment) the chassis did not bottom out. It wasn't until 13 inches did the chassis bottom out on the same manner as with the 8 inch drop with no collar adjustment. I then pressed on the suspension in all the same manner I did with the other test and with each (entire car, front, and rear) I not only felt more resistance, I observed an increased spring rate.

Per all of my tests and observations I lust conclude that shock collars do in fact put the suspension under increased load creating a more fierce recoil. It did in fact change my ride height and with all said and done with a balanced adjustment and a spring recoil I'm happy with in front and back I am 7 threads down on the front and 13 threads down on the back. My car has an even bounce to it through and through. Thank u Fred for some great advice to begin calibration of suspension as such, but it's just too apparent to me these collars play a large role in set up in the off road 1/8 scale class at least.
