Glad you're loving yours!

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!

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 :lol:

From the PSS9 installation/kit manual:

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...

chiketkd 11-08-2010 08:26 AM

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!

yale02 11-08-2010 07:59 PM

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

yale02 11-11-2010 09:18 AM

they arrived late yesterday! I'll hopefully have them installed within the next few days.

chiketkd 11-11-2010 09:37 AM

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.

Yep. Fiddled with it some more (I love that you can keep messing with them) and higher number definitely = softer. Here in NC they have nicer roads than SW Texas and I think I'll be going with a firmer ride.

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.

When you put the coilovers how much the car is lowered? Roads in my country sucks so i don't want the car to be too low. 2-3cm is enough

TopGear8 12-05-2010 08:48 PM

^The whole point of a coilover is the height is adjustable...Anywhere from stock height to 2 inches or more lowered.

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!

jrx13 12-29-2010 06:05 PM

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!

The parts you identified (F&R) look correct, but it's been almost 9 months since I installed mine.

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


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.

http://2475-stangtv.voxcdn.com/files...2/IMG_3136.jpg

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:
  • 10 adjustment clicks.
  • Uniform controlled pattern for each click.
  • Can be used with adjustable compression canister for a total 20 clicks of adjustment.
  • Comes with 1/2″ heim or 15mm heim shaft rod end.

http://2475-stangtv.voxcdn.com/files...2/IMG_3133.jpg

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.

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....

chiketkd 01-05-2011 09:53 PM

Well, from what the Bilstein engineer relayed to me, these new adjusters aren't available for any of the Bilstein PSS, HD or sport shocks at this time....

c_ls 02-01-2011 11:37 PM

Just ordered the PSS9s from tirerack for my R3. Looking forward to this season :D

lucifuge 02-27-2011 10:21 PM

Can someone please post the total range of lowering afforded by the PSS9's. (Living with a steep driveway I want to know I can lower it perhaps even marginally, if i have to.)

chiketkd 03-01-2011 08:58 AM

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.

lucifuge 03-03-2011 06:33 PM

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?

redline09 03-03-2011 08:10 PM

I heard there awesome

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? :(

TeamRX8 05-02-2011 09:11 PM

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

SOLO8 here references the "supplied washer" and you can see it in the 4th picture down.. https://www.rx8club.com/showpost.php...&postcount=182

That's what is confusing me :(

c_ls 06-06-2011 09:32 PM

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?

alz0rz 06-06-2011 10:04 PM

No clue what the cause is but I had the same issue. I had to lower the passenger side perch about ~.5" to get the ride heights in the rear more or less even.
