Default Need Help Lowering Rear Suspension BCR

I have a few questions for installing the suspension in the rear.
1. Is the spring perch (The Locking collar) supposed to on the topside, not in the lower bucket where I place the spring?. (So like in the picture with the strut, I reverse it?)
2. Is one of the rubber pieces are not needed. Is that true?
3. How would I lower my rear suspension. I am supposed to set the collars closer to the perch to lower correct?
4. If I do set the collars as close to the perch, Would it affect the preload?
5. After setting the springs in, I extend or shorten the strut to complement it?


Sorry for my bad English. LOL
Thanks in advance.

Spring perch goes on top. Remove the Lexus cone rubber thing on top. The Lexus rubber stays on the bottom, or you will clunk, trust me.

Consider getting adjustable links from Figs Engineering and installing those or you will have to take everything back apart because there is no adjustment on the rear wheels and it will ride on the inside. .

i have about 1cm of threads between the top perch and locking collar.

After setting the perch you jack up the arm until the spring won’t move, then go another 3/8” (you will need to measure a point somewhere) then you rotate the shock until the holes line up, that is preload.
