I have the same noise

I had that issue on mine too but I found out that you actually have to preload the springs quite a bit to get them to sit in a good spot and that actually gets rid of the harshness.

Thanks, I didn't pay attention but can you preload via spinning the bottom of the coilover mount or do you mean compressing the shock and bolting down? That could be it, because it sounds like under rebound there is play in the spring (hitting the housing).

You can preload by spinning the collars. I would suggest playing around and seeing at which point you can achieve the highest ride height (not preloading enough will actually make the car sit lower) and then make that the minimum preload.

I had already thought about this and had tried it this way first to get a baseline for height adjustments. I noticed no significant improvement in ride quality. Mind if I ask what knob setting you found most acceptable? I noticed not much variance between 0min - 6max clicks.

At zero preload, meaning the helpers were fully compressed, but little to no load on the main spring, my car sat as high as stock and you lose height adjustability (might as well buy a Koni). If these had the adjustable lower height bracket then we could mess around with preload all day long but zero preload also leaves you with virtually zero droop travel and a high ride height. I like some extra droop travel on my street dampers too.

edit: added pics at zero spring preload.

I currently have my R2's adjust to about 1" drop from stock.

I seem to be getting toward an acceptable setup for the streets ( still firmer than stock but the dampers are that way to match the stiffer springs and less shock travel than the stock shocks as a given ).

Currently I liked 2 clicks compression and 3 clicks rebound on the front. Slowly testing right now. I had the rear at 0 compression and 2 clicks rebound but at speed I would start to get some resonant bounciness that would cause slight steering inputs which I assume from the rear being too bouncy.

I am going to test 3/10 comp and 3/10 rebound front and going to try 3/6 rebound and 2/10 comp on the rear.

[swift996]

So I got the noise to go away. I did two things.

- Tightened down the top nut (the front drivers was loose and the rear passengers a little loose)
- I also raised the car about 2 threads up (adding more pre-load)

I don't know about it being any smoother but the clanking noise is gone.

It's sitting a little bit higher but acceptable...for those who wan't to go low, use caution on these.

[swift996]

Put a few more miles on, still very bouncy and a slight bit of noise from the front driver's side but not like it was.

I'm pretty disappointed in Eibach. They spent a ton of time in R&D and testing it but after having them for a week they seem like they were put together on the fly. This is typically why I avoid made in America products. For whatever reason it's rare that an American manufacturer/assembler can ever match the precision of foreign products. They obviously didn't spend a lot of time testing these on the street. The adjustable height with the amount of pre-load is a joke, you can't lower the car much but you can raise it 2". They should have also supplied a shorter end link as the OEM one places the sway bar very close to the lower control arm (not sure if it makes contact or not). All in all for the price point, they should have done a much better job. The performance is great but the sacrifice is a lot for anyone running on the street. I knew I was taking a little risk, I'll just have to live with it.

Really? At zero preload my car dropped about 2" after the springs settled (approx. 24.5 inches). That's what initially gave me some doubt to the zero preload. After playing around raising the collars for a bit, I got to 12cm, and the drop reduced to about 1" where I was aiming for. The ride became much more bearable in the sense that the springs actually felt like they were doing work.

I currently have my rebound at 2 clicks which feels decent. Quite honestly, the difference in terms of ride comfort with the rebound settings feels minimal, but 1-2 clicks seem to smooth the ride slightly.

With all this, It feels pretty good, except when I drive over long dips (sorry I don't know how else to describe it...) I get a pretty rough bump. BUT, that's still an imporovement from no preload because when I had no preload, the car would hop a few times and I felt like I was losing traction.

Also, my right front side started squeaking... Anyone have any idea what this is? I've read on other forums that it could be the swaybar bushing so I was going to try and isolate that issue this weekend.

Edit: I've also been talking to mark at eibach and he said that they're getting a test car on Tuesday so hopefully we'll get some answers from the manufacturers soon.

If you're disappointed in the product, then you should make it clear to Eibach that you are (don't just live with it). Eibach has their reputation on the line and so if they see a lot of customers dissatisfied with their product, I'm sure they will do something about it.

I however, do agree that for the amount of testing that they've claimed to have done for this, that there are many issues.

Edit: nm I read through the other thread and noticed that you are talking to Eibach.

Had some more time after getting back from my trip to visit family during the weekend.

Found a much better compromise in the settings. There is no doubt the ride is firmer than stock due to less shock travel and dampening rates.

With preload set such that the front was 25.25" ground to top of fender and rear set at 25.5" ground to top of fender, settings 3 clicks of rebound and 5 clicks of compression on front and 3 clicks for rebound and compression on rear. I have found a much more acceptable setup for street. It is more stable at speed and less harsh at low speeds. This is with the OTS spring rates 275/350. If you have stiffer or different preload then you should consider more rebound than you expect. Do not put too little compression as that allows it to be bouncy as well.

I am just happy that I could find a setup that worked as now I can focus more on testing on tracks I intend to run to take more notes on preferred handling before I look at different rates. Gotta drive this thing to the ground before I can claim to know what is best for me.

Oh forgot I have the camber set to max up front so it's just over 2 degrees camber in front and just under 2 degrees in the rear (I have cusco LCA and GTSpec toe links) and just need to test high speed stability a little to make sure I have the toe set just right.

Updated settings as I wanted it a little firmer at speed. Looking good so far but damn I can't wait for my Rpf1's and Direzza Z2's.

I'm not sure how to write this w/o making it seem like i'm bashing the product but I also bought this coilover set because I wanted to support an American company. I was disappointed by the product I received, lost a lot of time in the process. I waited ~2 months pre-ordering these thinking that time was spent on R&D. It's now been about <2 wks since Eibach took them back to address my concerns. Still no coilovers on my car yet my pocket has been short $2k~ for most of this year.

I do hope the Eibach company will allocate proper resources to R&D this product better.. I'm on the verge of buying a tried and true JDM product but will hold out as long as possible. Needless to say i'm disappointed on various levels but hopeful they'll make it better! The guys that work there are guys like us who are passionate about the automotive aftermarket. I hope they'll make it right.

I do see you've owned some higher end cars. I'm lucky enough to have done so also. I hope the positive reviews I read on the Multi-Pros were not written by folks who simply don't know any better.

Btw.. My Made In America Walbro fuel pump took a crap on my other car last week.

[Hanakuso]

I just got to Eibach and they currently have my car. I'll keep you updated on what happens. As of right now they are guessing they will have my car for a couple of days.

I agree, I knew I was taking a little risk with something untested but you'd expect a lot better out of a company like Eibach. I plan to follow-up with them later this week. Pulling a set of coilovers off isn't just a breeze on jack stands.

I'm not sure what I'm going to do yet, it's just extremely disappointing since we all waited a long-time and at the price-point, they can't afford to put this out in the market. I feel like I got a $700 set of coilovers.

I appreciate JoeBoxer getting good pricing and prompt delivery on them.

There's no way I could recommend these to anyone unless they were about $900-1000. I wouldn't even want to resell them because I'd be robbing someone.

On a positive note, these things do perform well. I enjoy the added stability and grip but I drive this daily.

[ayau]

For those that are disappointed, have you tracked with the coilovers yet? I have yet to track mine, and that's why I'm not going to give my opinion on them yet.
