I have Konis with an adjustable plate. I am currently using H&R 60 mm ( 2 3/8")coil spring. I want to reduce the spring rate and the shop (store) has the Eibach 2.5" coils available on the shelf. I did a test fit on the shocks and the Eibach sits "half way" on the plate (see photo). And when I push the whole coil on one side, it will sit near the edge of the plate. Is this safe for the track? I know 1/8" difference is small but I am afraid that having only half of the coil on a contact patch can damage my plate.

See if you can make an adapter that will fit the OD of the sleeve and the ID of the desired spring. I'm having a similar problem on my upper mount - going to make some spacer/adapters. If they're not sitting on it fully, then they're probably going to rattle around and shift. Since it's taken apart I would fab up a piece that will make everything slip together neatly and be fully seated.

I made that mistake and now my car's out of commission again.

 

More picts:

On the left side of the coil is the area of contact on the ajustable ring:




This is when I push the coil on one side of the sleeve:

 

hmm i wouldnt trust that for track use. Are you able to get a different adjuster nut or make something?

 

Why not use 2.25" ID ERS springs instead?

 

I know. Just that the shop had that model on the shelf and the next Time Attack is soon. Don't really feel like waiting a month to get. Anyways, I will be returing those and order the 2.25 ID.

 

If you are local stop by and we can throw some 2.25" to see if they fit ok. They should....

 

For sure the 2.25" will fit (I mesured the OD of the sleeves). Unfortunately, I am up north (Canada).
