Spacer Ring with Eibachs?

Spacer Ring with Eibachs?
Has anyone installed shock spacer ring(s) in the front (928 343 533 00) with Eibach springs to compensate for the shorter spring?
I've read that the height adjuster nut may come close to maxing out when setting factory height. I normally run on the lower end of the factory recommendation, so perhaps it won't be an issue.
Any insight would be appreciated. Thanks!

I run Eibachs front and rear and set the height at the lower end of the factory approved height range with no problems. No spacers fitted as I am aware.
No idea how far I could lift them up if I wanted to- never found any need to even think about it but then we have excellent roads over here with no pot holes.

I was able to get the front of my S4 to 175mm, the lower end of the acceptable range, with the Eibach springs and no extra spacer rings.
That said, I ended up with a mix of Eibach and sport springs to get the right balance between stability and ride harshness. In the end, your choice will be a balance between ride you can accept on the tires and wheels you like, based on your selection of shocks and springs, plus the condition of the bushings in your suspension. I've ridden in cars that owners thought were great, and I thought were horrendous. So there's a broad spectrum of "acceptable". Greg Brown mentions once in a while that he takes out more Eibachs than he installs.

Thank, Gents.
I think my GT rides like a Buick, so I thought I'd try the Eibachs out. I intend to stay with Boge Sports and continue running on 17" Cup Is. Perhaps I'm jaded by how my 911 rides (thicker torsion bars and Koni Sport Yellows) and how well it handles... stiff but not jarring.
I'm in the process of installing rebuilt arms in front, so those bushings will be new.

Still the best ride I have seen is stock springs and Bilstiens.
I just converted a GTS from some crazy aftermarket shiddy suspension with Konis and Eibachs to the stock springs and Bilstiens.
3 of the shocks were blown and leaking oil
I couldnt believe the owner drove this thing like this for many thousands of miles with the belief that it was better than the factory ride, it was way worse.
THEN,
Just got a phone call with The owner gushing about how perfect that car drove after my work was done.
He was exceptionally happy with the way the car drove like it was meant to.
And couldnt believe how nice the car really was, I have done a lot of suspensions and corrected many of them back to stock spec,
with the best parts,
you can have one of the best rides.
Really some of these cars with the aftermarket spring and shock kits are terrible.
Also consider the jarring thats put into the chassis will also loosen every nut bolt and screw on the car over time.
I know that the intention was for them to be set up for use at the track but in reality most of these cars are 90 % street cars.
A good set of factory springs and fresh shocks makes all the difference in having a perfect handling GT machine,
One that wont let you know about every undulation that the wheels follow.
I am happy to take people for rides in my yellow car its really a great driving machine for hi speed use.

That is actaully one combination I've not experienced. I've 'removed' Eibachs/Bilsteins and replaced with adjustable Konis and owners are very happy. Most of my folks are 'I want OE' so stock springs and stock Boge's.

I've removed quite a few Bilstien/Factory spring combos and changed them over to Koni/Factory springs because the ride was too harsh for the customers. I always set the Koni's spot in the middle and everyone is very happy with them. Only had one customer in years prefer the Bilstiens but those were replacing factory sport shocks that were toast so I suppose that could be it. Those were also a set of B's that I had taken off another car.
On my own, I plan on pulling the rears out and stiffening those up as Worf does and see how it goes. Right now the balance is good but I'd like a bit more stiffness in the back. I've run Eibach's/Boge and that was too unpredictable. Eibach/Bilstien and it just beat the **** out of me and am quite happy with Koni/stock.

Bottom line- with suspension there are no free lunches- you gain something somewhere you lose something elsewhere. I appreciate that some folks reckon the variable rate Eibach springs do not work well. I took the point of view that if my dear friend Kim Crumb could fill his trophy cabinet the way he did using the kit he developed with Eibach then he must be doing something right and I am equally sure that Dave Roberts would not have been selling them if they were junk. Clearly it cannot be expected that they should be a "jack of all trades" and "a master of all trades" but for a dual purpose vehicle spending most of its time on the streets they sure take some beating. In fact my setup was so impressive it blew the mind of a German factory instructor whose 911 turbo's *** I was waxing at the Dubai Autodrome. No contest on the straights but in the bends it was another matter altogether. It was a training session and no overtaking was allowed- he was adamant that he would go a fast as the chap behind wanted to go and I simply put the nose of the 928 up the inside and outside of him to tell him "I'm here".
It all boils down to personal taste and expectations. Nothing really wrong with the stock suspension- personally I found it somewhat ponderous on my late S4 during turn in but a tad more comfortable that the Eibach setup.
