Ben in Plano, TX

Bob,

With the PSS-9, RS bars, and the RS droplinks (not adjustable) I was able to lower the car as far as I wished (in fact I've raised it from where I initially set it). I had it so low at first that a fellow Rennlister referred to it as a 'lizard' setup!

As you know, the RS droplinks are curved and longer and connect to the rear sway bar beneath, rather than above, the track control arm.

Anyway - just thought I'd clarify that with RS bars you don't need adjustable droplinks to achieve lowering at or below RS specs.

That is true Ben. Again sorry if I left the impression that adjustable drop links are required to go to a lower ride height. It is the adjustable sway bar under the toe arm that allow the mounts to be lowered and hence the car to be lowered. The RS drop link, the TRG drop link all do the same job with the adjustable sway bars. It is just that the adjustable drop links allow for more flexibility in tuning out any preload on the sway bar, and further adjustability to set the bar distance under the toe arm without repeatedly taking the shock off and turning the drop link mount up or down from side to side. Any of you that have done this know install what I'm describing....

These pics may help you understand things a bit more:


TRG rear sway bar with bob's adjustable drop links and TRG sway bar mount. Notice how the sway bar is under the A-arm. Also notice how much extra space is available above the sway bar mount to lower the car.

This is the RS rear bar with the RS adjustable drop links.
Notice again how much space is above the sway bar mount.

And here is a pic of pss-9's with the std sway bar mount, std drop links, and OEM sway bar. Notice how it's ABOVE the a-arm. Not a lot of space on top of the sway bar mount. And there about 3 mm of space before the sway bar hits the a-arm.


I hope these pics help.

Regarding PSS9 with 21mm turbo rear swaybar and ride height...

I don't get where the "issue" is? My car is currently at about RS ride height (at or just under 25" to bottom of rear fender), and with the PSS9 and 21mm turbo bar with stock drop links, all is well! There is no noise, NOR are there any clearance issues --eyeballing about 3/4" clearance between A-arm and swaybar. Either my car is the aberration, others' cars are, or we're misunderstanding each other somewhere along the line (for reference, I have a 95 narrowbody). Hope this helps someone, or maybe someone can clarify as this "swaybar/droplink/height" issue seems to pop up often.

Edward

EDIT: BTW, just for clarification, my swaybar is about 3/4" ABOVE the A-arm similar to the above pic --Thanks for the pics, Jeff.

Dave Hanley

Interesting, as I have PSS-9s and turbo swaybars front and rear on my '95 narrowbody 993, and neither the droplinks supplied with kit nor the stock droplinks would fit anywhere close to my desired RS ride height settings at the rear. The fronts fitted fine.

The shop in Houston that fitted the kit therefore manufactured some adjustable droplinks, that look a lot like Viperbobs. These mount the swaybar above the A-arms. All is now well.

Edward,

That is interesting. A couple of questions. Do you have the new Bilstein rear hats on your PSS9 set-up? If not, do you have the old syle top hat with the stock susepnsion mount, or a monoball setup?

Can you take a picture of your setup like Jeff did?

Thanks.

Edward

Bob,

I have the Bilstein-supplied hats; no monoballs. Here's some pics.






I think I havethe answer: I don't have an extra locking collar under the spring. It seems my swaybar mount butts right up to the bottom of the collar.
Hope this helps....besides, I'd like clarification as well

Edward

Oh, and THANKS to the gentleman (of whom I apologize I forgot your name) who sold me this bar. You're a kind Rennlister!

Edward,

What is that bolt on your swaybar mount? I don't have that on mine, nor does the one in Jeff's picture.

Hi Greg,

That was Mark's solution (at Hergesheimer Motorsports) to the "rotating mount syndrome." Though he has a more beefy "motorsport" solution, this fix is plenty good for the weekend tracker, he assured me (Mark and Laura are great, BTW --highly recommend them ...no affiliation).

PM me for details as I'm not certain I should be discussing publicly the specifics of what he did. I hope the picture doesn't give away any "trade secrets" --sorry if I have done so inadvertantly
(in which case I'll pull the picture!!)

Edward,

I was thinking they must of done something like this. It was either that, or they just did not install the helper spring, or they had milled down the vertical size of the mount on the strut. What they did was cut a relief slot down the axis of the shock in the link mount. Then they drill a hole and apply a bolt to pinch the mount to the strut. Then they get rid of the upper lock ring for the mount. They then use this platform as the lower lock point for the spring perch. So they relieved the vertical space by getting rid of two lock rings.

Greg H.

Now that I look closely, I see the cut. That Bob - he's one smart cookie! (As is Mark for coming up with the idea)

Interesting, but I'll be as low as I want to go with the Bilstein supplied parts.

I take it from these postings that the adjustability problem is only in the rear. Seems to me that a good solution would be the M030 (22mm) bar in front with the adjustable RS (20mm) bar in back. Thus, you can get some adjustability, can lower to your heart's content, and can save $500 by using M030 bar in front.

TheOtherEric

BTW, I know of a good price on a set of TRG swaybars. PM me if interested.

OK Guys - Here's my 2 cents. I have recently installed the HD's, the ROW M030 springs and bars and have a nice set up with a ride height of about 25 3/4" all around( corner balance inculded) on my 97 cab. My correspondance with Gert indicates that if I want to go lower I need to go to the RS bars (rear at least) to go any lower on the ride height. This is because the current rear bar goes between the suspension parts and the RS bar goes UNDER the suspension parts. Therfore the RS bar is needed to go to the RS ride height. Hope this is making sences. I am debating on this matter and MAY go to RS bar. Hope this helps the discussion.

I don't know what 24.75" translates to, but I had the same setup with the 20 mm rear bar using the Bilstein supplied drop links and my car was at RS ride height with a mm or so to go.
