Lowering m-sport on eibachs

NathanZ4C said:
Well I ordered my springs direct from eibach. Went for the coupe specific set. Did the rears myself and took no time at all. Took the car to a local garage to do the fronts as I didn't have a spring compressor and I didn't really have the time to do the fronts.

They were only done yesterday and I've been for a 45min run and over speed humps etc. The front end looks far higher than before. I can fit my whole fist in there :( I'm hoping they will settle down but I can't imagine that are going to drop enough. I'm also tempted to say they have sent me the wrong springs however I know it's still early days

Anyone else had the same issue? Can anyone read the serial number on their springs so I can cross check them?
What part numbers were you sent?

I have Eibachs on a Sport model roadster - dropped mine by a further 15-20mm.

Bing, do you have any side on photos? How did you rate the ride after fitting, any worse? Fitting 19" on mine certainly made the ride a bit more crashy over bumps, I need to lower it a little but not at the expense of even worse ride :?

Cheers
 
From your pics, something is wrong! Your front should have been lower, not higher. If you look at my earlier post you, you can see what I had in drop with the same car/suspension as yours. I'm at work and can't do the research, but try to compare my part number to yours for the springs. Other than that, it almost looks like you could have springs for the Z4M, which has a heavier engine and would require more spring up front. Those springs with a lighter engine would sit higher. Could also be a difference isn perch height between the M and non-M. As far as the springs on my car, they did not seem to settle any appreciable amount.

How difficult is it for the garage to have installed the spring incorrectly?

think they have been fitted incorrectly to be honest, I'll dig out the receipt for the ones I bought a while ago and see what the serial number was.

this was the box:

and this is what they looked like:

On the box it says E10-20-010-05-22

On the front springs it has 112000101VA

just zoomed in on the photo, 112001001VA so unless you've typed it wrong you may have the wrong part.
 
I ordered mine from eibach, specified I wanted m springs and was sent the springs for the reguler e 85. Luckily I cheked the serials pre fitting and noticed. It could be theyve sent you the wrong springs...

Theres something wrong with the front suspension definitely. .. :cry:
 
PM "Z4M-2006 " , , pretty sure he,s dropped his last 3 x Z4,s on Eibach kit,s , this being one of them

I've done a quick search on both of the serial numbers. They are the wrong springs. I need to check the rears but I might have got lucky with them.

I can't tell you how angry I am right now. I've just paid good money to have them fitted and I can only begin to think how the conversations going to go on Monday when I call them up and respectfully request they refund the costs of reinstalling them plus my wasted time off work having to ferry the car to and from the garage.
 
iirc the rear e46 spring I had kicking around when I replaced both on my m3 was virtually the same as the z4 one, however the spring rate will probably be wrong, i'd bite the bullet and change them too.

To answer the ride question - less harsh over good-ish surfaces than OEM, harsher over rough or roller coaster surfaces. Must be because they are 'progressive', so the more that's asked of them, the firmer they are. I think :P

To the OP - that's not ace at all, hope you get it fixed soon. Have you got the right part number now ?
 
I'd go so far to say that your rear look lower than mine do now. So there's a chance they are wrong too.

I have what I believe to be the part number for the front. Not the rear.

Just a shame I didn't notice before they were fitted. Got to wait until Monday morning to see how this is going to resolve itself.
 
The springs all have the wrong number on them - they've given you the right box with the wrong springs in them. That's shocking. Tbh the supplier should foot the bill for you having them swapped over... Though they'll probably just say you should have checked the part numbers before fitting :headbang:

Of course the garage didn't notice either...
 
To be fair to the garage they did what I asked them.

I guess Monday will confirm how they are going to deal with it. In my defence there isn't any reference to the correct part numbers on the box and it's pretty hard to find anything on the net about them either.
 
I have to tell you, I googled 'Eibach pro springs e86' and found the right part numbers in about 60 secs. However, the box is marked correctly, you shouldn't have to check the part numbers of the items themselves really. Where did you buy them from ?

....damn, that looks perfect! I'm doing my best to stop spending money on my car and you have to go and post those pictures :wink: I think I can cope withe the ride on that basis, it transforms the look of the car without being ridiculously low. Thanks for posting :thumbsup:
