I,have had a Gc coilover kit (with Koni shocks) laying around for 1.5 year now and toay my helper springs from Eibach came in.

Now through the time the parts have been here I have buuild up the struts and taken them back apart in order to investigate some issues.

Today, when reassembling the parts I noticed that the coils (front and back) have different recess lips on the inside. These determine ride height.
Dum as it may seem, I have mixed them and don't know which coils is front or back :-s

2 coils have a 3.8cm debt recess
2 coils have a 5cm debt recess.

This viewing from the underside of the coils Without the black ring in.
Can anybody tel me whch coil goes where?

Many thanks,

Neal

Are you talking about the threaded sleeve that goes over the shock?

Speedworks

correct. on the inside there is a lip machined which is supposed to rest on the black ring, which on it's turn rests on the clip on the koni shock.

Well, this lip inside the threaded sleeves is different front to back. just trying to find out which one is front and which is rear

Honestly, i've got them and mine were different too. It doesn't really matter either way. You're going to be setting the ride height with the threaded perches. 1.2 cm should make any difference, as you ought to be able to adjust it to both higher and lower than you'll want it in the first place.

Speedworks

Yes and no... it will affect how low you will be able to go frnat and back and wether you will be able to level the car (no front down,rear up situation).

I have also mailed GC for info.

Maybe.

It's not likely that either of your settings will be at the absolute end of the collar adjustment, so you can level it out.

GC mailed back to me. deep counterbore is for front shocks

Koni and Eibach are very good products as single items. Eibach has some complete coilover kits for euro market and they also use Koni shock for those kits.

I also had a problem with the ERS springs being loose on the shock when the threaded nut was more than half way down the sleeve (not mounted on car) so I contacted Eibach UK and they had helper/tender springs for this application (2.5" springs) and the go-between centering pieces.

Helper springs Eibach PN: 01-250-00
They are just there to fixate the main spring. They are not for load purposes. I guess Eibach can also provide these for load applications as well.

You'll find after you install that this was wasn't really nessesary, I'm surprised GC didn't tell you. They're only loose when you have the car on a lift, there's virtually no way for them to be loose while driving the car. In order to even adjust the collar, you have to get a whole end of the car in the air. If you just jack up one side of the car (left or right), you can't even turn the collars.

As they explained to me, you'd have to be airborne in your car for a long enough period such that at that point you'd have alot bigger troubles than jiggly springs.

Many countries in Europe require the springs to be tight when the car is up in the air (notice that he lives in Belgium). In this case, a helper spring would be required to pass that country's road-worthy tests.
