Eibach Multi Pro R2

[steve13gt]

I believe this is a helper spring not a tender spring, as I can fully collapse it using one hand very easily, and also the kit that gmitch has is a different part number as 2007s had a different kit. This is 35125.713

My front spring uses a helper spring much like the one shown in this picture ( I know its being used on the back, but again I have a newer kit)

but in my instructions it mounted the same as mine.

Can you scan and post those?

I am only running 255s, so I assumed that sway bar mount was okay

Your out of your mind if you don't check the clearance. If it does not have enough you will cut the sidewalls of your tires and end up driving on your rims.

Check clearance=free

Not check clearance and fail=Big $$$$$

Regardless of the spring semantics you still put it together upside down.

 

[steve13gt]

I didn't put anything together. They came out of the box like that, and are the same as shown in the instructions.

Here some pictures showing the helper spring fully collapsed when parked, its very hard getting my camera up in there so sorry for the lousy pics. Last one is a picture from the instructions, showing them the same as mine

 

[Department Of Boost]

Well that's not right. If they came out of the box like that Eibach put them together wrong.

What are the numbers and the front and rear springs? It would probably be a good time to see if they sent you the correct springs too.

360374 on springs.. the dampner pn is 35125.8300

360374 on springs.. the dampner pn is 35125.8300

There are a LOT more numbers on the springs than that (I can see them in the fuzzy pics).

It looks like the front springs are 800.250.225's. That would make them 8" long x 2.50" diameter x 225#/in. If that is the case those are the WRONG SPRINGS up front.

If you can post all the main spring numbers for the front and rear I can tell you what you have going on.

 

[steve13gt]

Those are the front spring p/n Also on the spring is there 1800 Number.. We are still stuck in a storm, I can't go out and check my rears atm

Anyways, Eibach says they are installed correctly, your kit is older and different. I thank you for your help but I am unfortunately no further ahead.

I tried to buy the best of the best, apparently made in USA cant guarantee everything

Unsubscribing because you're helpless.

The most common problem in manufacturing is miss labeling. Eibach is suffering a rash of that lately. Many of the web sites show the wrong part numbers for the front and rear springs with heavier rates on the rear which is wrong and lighter rates on the front which is wrong. Someone made the same mistake when they released the part numbers and spring rates for the Ford springs. Loads of people believe it to mostly because they don't understand springs how they work and how rates are chosen. No Mustang since 2005 has had heavier springs in the rear.

I am helpless? What information have you posted so far that has gotten me any further. Again I do thank you for your help, but I am no further ahead. You said my kit is installed incorrectly, the manufacture said its installed as intended. Who would you believe.... My rear springs are not my concern at this time..

Again, Thanks for trying, I do appreciate it. But my kit is different than yours, so your experience was different. This Kit, came pre assembled, and I installed it according to the provided instructions. Tell me what more I can do, to not be helpless.. Other than hope eibach figures there own shit out

In the instructions does it also tell you how to assemble the coilovers? I cannot tell but that looks like a "stock" or generic photo for advertisement.

Did you tell Eibach how they were installed?

Because I am with gmitch it makes no sense why the tender springs would be at the top. It would inhibit their function and most likely cause the issues you are having.

Here are pics of the EIBACH SEMA 2011 Mustang GT with R2's installed. Notice where the tender springs are?

[steve13gt]

They don't tell you how to assemble them as they are already assembled. But the pictures used for the install show them that way. The spring in mine is much lighter than the one you show


Sent from my iPhone 5

However this does make me think, they should be installed that way

Those spring rates are wrong and Eibach knows it. How they managed to release that erroneous info is beyond me. The heavier springs go in the front the lighter springs in the back.

 

[DRock]

Those spring rates are wrong and the helper doing should be on the bottom. I myself would do as g Mitch has said.

 

[steve13gt]

Called Eibach just now, Helper springs are supposed to be at the top...

....... This thread=FAIL. It sounds to me like you are talking to a dipshit employee who is clueless (all too common nowadays when you call) or you got shipped the wrong kit for your car. People have posted tons of pictures with it the opposite way and you're still not convinced. You know, maybe its just me because I have a nice roomy heated garage with a lift and all, but I would at least take it apart and try it the other way and see. If it works then you can call Eibach and demand they fire the idiot who put your kit together and also the idiot who keeps talking to you on the phone. If it doesn't, take it apart again and put it back like you have it. Its a pain in the ass yes, but you sure spent enough money on the stuff to at least get it working right. Trial and error is sometimes necessary in troubleshooting.

 

[steve13gt]

I dont have a hoist or any heat, just a wet driveway with pouring rain for the last week. They told me those pictures are of the older kit, and prototypes. Its apparently being forwarded to a manager of assembly or something similar.. Unfortunately everyone is at SEMA so service =fuck all

Also I am not convinced how it being upside down is my problem. I checked for clearance and the helper spring is not touching the bumpstop. Even with all tension off car jacked up I cannot rotate the upper spring seat. Even with the springs not touching it
