My pss's just came in today and while doing some research on installation I was wondering if anyone can confirm my knowledge. In the pic posted the bumpstops go UNDERNEATH the protective dust sleeve and the OEM top hats go underneath the screw nut and above the large washer?
is this the correct order from top to bottom?
screw nut
oem top hat
large washer
sleeve
large washer
bumpstop




looking in underneath the dust cap with the bumpstop shown and then the large washer above it

Now I havent even taken the stock shocks out of the car so I have no idea how the OEM top hats look in person but I found this other pic of a bilstein pss9 with what looks like the bumpstop is placed above the OEM top hat? is this correct? It looks like this shock was assembled in this following order..
nut
large washer
bumpstop
oem top hat


also is it preferred to position the bumpstops to the highest point possible (closest to the tophat) to prevent unneeded interference?

 

In the top pic you can toss that washer if you want.

The second pic is correct.

The third pic is not the bumpstop, it's the top mount isolator bushing.

 

thanks mac!! But in the third pic, is the large washer in picture 1 what is above the top mount isolator bushing in picture 3?

 

In order of placement on the shaft assuming nothing is on it.
1. Bump stop
2. Curved washer
3. Protective crappy blue sleeve and stepped washer attached to blue sleeve.
4. Flat washer (can do without if using stock bumpstops, not sure about the black bilstein cheepies) this washer may need to be under the top hat vs under the nuts for clearance of the adjuster to the hood.
5. Top hat
6. Two nuts for PSS9? and one nut for PSS.

How I installed my PSS's
1. Stock bump stop
2. Curved washer
3. Stepped washer removed from blue sleeve
4. Top hat
5. Nut

 

did you cut your oem bumpstops mac? if so how much did you end up cutting off?

 

FWIW, I cut my 2 inch bump stop down to about 1/2 an inch for my Koni setup. You might not be able to go that low because you have a mono tube. To test this out, compress your shock all the way down. Now measure how much of the shaft sticks out above the shock. Measure to the step in the shaft where the large washer sits. A little more than this height will be needed for the bump stop to keep the shock from destroying its self.

 

Do not compress your shock completely. The body is much longer than the shaft. You will loose oil if you do.

I did not cut my bumpstop and did not need to with the stock top hats unless you want your fender liners all jacked up.

 

looks like ill be going with uncut OEM bumpstops, thanks again robinson and mac for your input.

 

Here's a pic at full bump, this is as high as I can jack this wheel up. I did this to make sure I was using all available bump without the possibility of the tire catching one of the fender tabs and jacking up my fenders.
I ran this setup with 225/45/17 on stock wheels as well as 245/40/17 on a 17-9 63 as shown in the pic. There was slight rubbing on the fender liner and the fender tab clips.

 

My tabs are also bent in a bit just to be sure.
