Default 993 Bilstein Suspension Question

Hello All,
I would like to know if installing Bilstein HD shocks on all 4 corners with EIBACH PRO-KIT SPRINGS 7208.140 will achieve a euro spec M030 ride ?

Are the Bilstein HD shocks adjustable within the threaded portion of the shocks to achieve a euro spec ride height?

Thank you in advance for your advice.

I think that will depend on how far the shock bodies are threaded. I know that there are two different lenghts available. Someone with more specific knowledge will chime in shortly I am sure.

I didn't think the shock bodies are threaded for ride height adjustment on the Bilstein HD shocks.

All Bilstein HD struts have the "extra" threads. A number of years ago there were 2 different struts.
In any case, you will have no problem getting to that ride height or lower, as long as those springs allow it. Pretty sure they do but I am not intimately familiar with them...

My car has HD's and TechArt springs which I have heard are made by Eibach but may be very different from the Eibachs you are asking about. With my rear shocks adjusted for max. height, my car still sits too low for my taste. It's below euro M030 height and closer to RS height. There is more range on the front threads to go higher but not the rear.

Mark, all the on-line parts outlets were showing a Bilstein with a welded on lower spring mount.

I've now found a pic of a Bilstein HD unit and see that the body is threaded. Can you confirm that they are the following shock...and what are those "extra threads" all about that you mentioned?



THANKS!

These are exactly the type of Bilstein HD shocks I've purchased.

I wonder how they are going to ride?

I find my stock suspension harsh enough on rough roads with the 17" wheels. Its hard to can't believe that is OEM.

I don't want to go any stiffer and I want to maintain the stock ride height.

I too have Bilstein Hds and while the ride is certainly nothing like luxury, the handling is superior to what I experienced before the conversion. With the old tired suspension, I bottomed out at ever snake hole and frog crevice. I now pick the local roads I use based on the surface and not distance because I got tired of waiting to see if the windows will pop out. Do I wish the ride was more "compliant"? Hell yes! But then my son reminds me , "It wouldn't FEEL like a true sports car! With the HDs and 030s, I do maintain very flat in the corners. Good luck with your application! As for me, the next chunk of change I get will involve installation for the 033 springs in combo with the Bilsteins.

FWIW, Sachs is developing a line of performance dual purpose street/track COs that appear to have reasonable comfort and good performance. Some folks who have tested both the Bilstein and Sachs off-the-shelf version COs indicate the Sachs offered a little better ride and performance - but this was a subjective review by several test drivers so YMMV.

I have no association with Bilstein or Sachs but they both make decent shocks in my limited experience. I always thought the Bilsteins had a harsher ride than necessary for dual purpose use. I also did not care for the ride quality of the Koni Sport shock package for the 964 compared to the roll stiffness and overall damping. That's why shock tuning is a lot of science and some art too.

I'm leaning in the direction of Bilstein HD's and Eibach progressive springs. I believe it's not only a significant upgrade from stock, but also adjustable to some extent in terms of a M030 Euro stance and ride.

Thanks for the input!

For a daily driver are the koni's a better choice than the bilsteins using the MO30 ROW springs??= Of course my dealer said to go with the stock shocks and they will be best???

For the OP, I suspect that the Eibach Springs will put you below ROW 030 ride height even with the spring mounts set all the way up. After all, these springs are meant for lowering the car while using the original shocks. Why are you not using the ROW 030 springs instead, that are available e.g. from Carnewal?
