Pss9 Installation Help.

I'm not an expert but I want to attempt the coil over install myself I just don't have instruction since I purchased these used. if you have done this before please chime in and help me figure it out. once I can get the installation worked out in my head I will proceed with the installation.
Any help would be appreciated. I will move on the the fronts after this. I'm still researching it. i will be using Vorshlag camber plates just checking on a few things before I post pics

Lets start with the back. here is a pic of the stock setup via Real Oem. What parts am I reusing?



here is a pic of the rear parts I have.



so far I get that the rear perch gets the rubber piece that goes between the body and the spring perch and the blue washer goes between the rear coil and the perch like so


What are the other 2 blue washers used for? do I double them up? - I figured this out the other 2 are for the fronts...
Ok moving on. heres whats left.


next I'm moving to the rear shock assembly. I have 4 washer that appear to be the same and I have 2 washer that are concave. once the dust boot is installed I add 1 flat washer like so:


what parts go next from the oem side?

I figure the next pieces should come in somehow in this manner ( with some OEM piece I'm assuming in there)


Now I have these pieces left. where do they go? where does the other concave washer go? what are the other nuts used for?



Heres the assembly without the shock


Sorry if these seem like stupid questions. I just don't want to sit there for hours when everything is apart trying to figure out what's right and making sure I don't screw something up.


Thanks,

Jorge

Hopefully this manual answers at least a few of your questions:

Will check on this thread later and answer your remaining questions at that point if I can.

Thanks, It looks like I get the assembly now but I have a few questions.




Am I taking apart the upper OE bolt piece? part #7 in the OEM pic.
I looks like I don't use piece #4 either.

Hers my impression of how it goes.
from the shock..
1. Flat washer
2. OEM piece #6 using the Bilstein washer (tube piece)
3. OEM Piece #5
4. OEM rubber piece from screw assembly (you take apart?)
5. 2nd Flat washer
6. Bilstein nut
7. Bilstein lock nut
8. Blistein shock adjuster.

where would the body of the car sit in between these pieces? I don't use the concave washers I got?

after I figure this out I have a question regarding the Dinan 10mm rear shock mount kit. I have one that I purchased that I was going to use on my Dinan stg 1 suspension upgrade, but decided to go with the Bilstein setup instead. can I still use this kit or am I asking for trouble? here's a pic of the parts for the Dinan setup. If I cannot use it that's fine, I have it so I thought I would ask. also If i cannot use it I will be selling my Dinan Springs with this rear upper mount kit and Koni yellows if anyone is interested.
Thanks,
Jorge


Dinan Rear upper kit. adds 10mm of suspension travel - I honestly doubt I can use it or even need it.

I would not install the Dinan. The Bilstein was engineered to use OEM parts so use those instead. Also, you need to cut #7 on the first photo from the OE part to use on the Bilstein. So what is left is a shock bushing. Seeing that you have the Dinan bushing, you could potentially use that but I would just prefer not to and sell that kit.

I would also suggest cutting two small holes on the gray panel so you can adjust your rear shocks easily.

Thanks, I figured it would not work since it was meant for a spring setup not coilovers. do you know what I use the concave washers for?

EDIT: Concave washers were extra washer they left in the kit. not needed.

Thanks,
Jorge

Bump.

Are the bushings circled in red supposed to come with the PSS9 kit, or are the OEM bushings re-used? My kit (used) didn't come with the bushings, and my OEM bushings don't fit.

Sorry for the stupid picture.
