D2 coilover proper setup
So I've been researching like crazy trying to figure out if adjusting the preload and ride height is different for d2's compared to my old BC racing coilovers.(see how coilover spring sits against top perch not against camber plate like d2)
I noticed that the d2's don't have a seprate top perch above the springs which would of made it easier to spin the shock body to lower and raise the coil-over without messing with the preload. (see how spring sets against camber plate)
The D2's however the springs sit all the way up against the tophat and when I went to raise the car I noticed that even though I had both lower collars tightened into each other and I spun the shock body to raise the car that the springs began to preload??? Furthermore, the strut length shortened greatly too? My question is this: Do I have to set zero preload as it comes from the factory or is zero preload done only once the desired ride height is set?
When I set zero preload with the car raised slightly I noticed it shortened the length of the strut greatly. Is it because of the design or am I totally missing something? This is not my first set of coilovers, but it is the cheapest set I have bought
. I have used JIC's, Tein superddrifts, Bc coilovers, tein HA's, but these are confusing me as to why the strut length shortens when I raise the car and set zero preload?

So does this make sense:
Thread the lower shock body downward to increase the overall shock length and decrease the vehicle ride height reduction. Thread the lower shock body upward to decrease the overall shock length and increase the reduction in ride height. Secure the lower shock body locking collar once the desired shock length is reached.
Thus if you raise the car it will shorten the shock length at zero preload, and if you lower the car you essentially lengthen the shock length!
If this is true you would want to add preload to keep the shock length longer if you raise the car correct? Also would loosening the top bolt on the strut do anything when or after adjusting the ride height?
