Anyone here run Bilstein PSS9's?
I'll crank them all the way to 9 and see what the ride does. If my car transforms Michael Bay style into a Buick Roadmaster you might have a point

Eh what? I could swear it was the reverse. I started off at 5 and turned them all to 1 and I'm positive the ride got softer. Now you're going to make me fiddle with them again!

position 9 = soft (clockwise direction)
position 1 = firm (counter- clockwise direction)

Whew, just read through all 19 pages. I have a set of Pss9's on the way. With any luck I will have them installed in time for my next autoX event.
Hope I have the stock parts needed to do the install. I currently have koni yellows installed and don't remeber if anything was reused from stock...

Congrats on the purchase. It's now been several months since I did my install, but I think you should be fine. If you run into any issues definitely ask away!
Thanks! I will ask if I get into trouble. I just got the tracking confirmation today; should have them installed by the end of the weekend! I am going to run them stock for this season whilst I research revalving and possible higher front spring rates from swift

Congrats! Definitely refer back to the install pics that S0l08 posted earlier in this thread: https://www.rx8club.com/series-i-wheels-tires-brakes-suspension-55/anyone-here-run-bilstein-pss9s-140733/page8/
They definitely helped me out with my install.

These things rule. I'm quite glad I went with them vs. the old standard Koni/Tein setup, especially since I can change the ride height later down the line if I get tired of the car being this low.

One thing though, on the highest setting I don't think you can reach stock ride height on the PSS9's. I'd estimate that it's similar to the drop from koni shocks (~0.5" or 1.25cm). So eleos, if you can live with a 2-3cm drop, you should be fine!
Ok so I plan on getting PSS9s someday (maybe around tax refund time). I want to gather the extra parts so when I have them I can pre-assemble the coilovers and have them ready to install, instead of taking out the factory struts and transferring all the bushings & mounts.
Let's start with the fronts. From reading the earlier install posts, I only need the parts numbered 7,8,10 right? No need for the sleeve, part number 11 or part number 6? 9 is just paper so I can transfer that.


Now for the rears, I'll need part numbers 9,11,17,18,19 correct? No need for 7 or 8? 15 I can just transfer too.
Thanks for the help!

Looks like Bilstein has released a new adjuster for their shocks at the PRI show:

P.S. I'm trying to get confirmation that it can be fitted to a PSS9/PSS10 coilover along some details about the cost involved....
PRI 2010: Bilstein Shocks New 10 Way Single Adjustable Shock Shaft
by Bobby Kimbrough on December 11, 2010
Bilstein Shocks has added another option for their BGT, ASN, SN and SNS series shocks, which will make it even more tunable for the driver and crew. We talked with Pat MacCaulay, Motorsports Shock Expert at Bilstein Shocks, about the new release. Pat told us that this adjustable shaft had just arrived from their research and development facility late last week.

We asked MacCaulay what applications this adjustable shock shaft would be useful in. He responded with, “Any application where you want an adjustable shock, or any series where adjustable shocks are allowed.” The primary target for the shafts are Late Model race cars (dirt and asphalt), Modified racecars, street/strip cars and road racers. “Even hot street cars can benefit from these adjustable shafts.”
They are available in lengths from 4″ to 9″ in one inch increments for the BGT, ASN, SN and SNS series shocks, and will work with coilover or big springs. These can be picked up in check valve version, which controls the rebound and compression uniformly, or in unchecked version for starting set up or road racing.
Features of the Bilstein Shocks 10 Way Single Adjustable Shock Shaft:

MacCaulay was quick to point out that; “This adjustable shaft has the most uniform pattern of adjustment, per click, that has been designed.” For proof he brought out the shock dyno graph that had just been tested at their Southern California facility.

This optional adjustable shock shaft seems to fill the need for racers that want a little more fine tuning adjustability in their Bilstein shocks. For more information on Bilstein Shocks or the new adjustable shock shaft, visit them at www.bilsteinus.com.

I'm not checking this thread as much, as I'm running in G-stock this season (still have the RX-8 though). Never played around with my adjusters to take the car to max or min ride height on PSS9's, but my guess would be roughly 0.5" - 1.5" lower than stock (at least up front).
From center of wheel to top of wheel arch this would translate to a front ride height of 14.0" - 13.0". When my front ride height was was at 13.5" (on the stock coilover springs), I remember being around the middle of Bilstein's adjustment range.

How would PSS9's compare to TEIN Comfort Sports purely in terms of daily driving comfort (on the kindest settings for each application)? On paper, the PSS9's come across a LOT firmer, but in reality due to the tender spring on the PSS9s, maybe they are very similar?
Ok, so I obtained a used set of PSS9's but I'm pretty sure I am missing something here.. perhaps a washer that Bilstein provided? This is a pic of just one of the fronts of what I got.
Also, is that blue plastic "ring" supposed to sit on the perch flush? Because it seems like it's too small to fit over the inner diameter of the spring perch.. any clarification?

the OE bumpstop with metal cap is the likely item, along with the OE bushing cups, just a guess from the pic and my knowledge of the parts in general, never had a set of these particular shocks
That's what is confusing me
I have these installed on my 2010 R3. Many thanks to chiketkd for assisting me with the install via PM.
Anyways, I want to raise the rear a bit, but I am already at the top of the recommended adjustment range. Would raising the rears 5mm or 10mm above this range be hazardous? I have the Racing Beat sway bar installed in the rear if that makes a difference.
Also noticed the drivers side is about .3" lower than the passenger side in the rear. This is with both the lower collars set to equal heights. Would anyone happen to know what could be the cause?
