Coilover Identification Help ... Possible Group N

[blatant]

Hey all,
I purchased an e36 m3 sedan a while ago and it ended up coming with some Bilstein coilovers with eiback springs and TMS camber plates.

I only have 2 of them and was hoping to verify they are actually Group N. I'd like to decide if I should sell or use.


EDIT: Anyone know how much these are worth?

My only doubt is the adjustment knob for damping. I was under the impression that the group n coilover kit was not adjustable damping.

I'm not opposed to throwing them on, just waiting for warmer weather and trying to complete my game plan for the spring track car build. Non registered, track only.

Appreciate any input.

There are two versions of group N coilovers. You have the more rare adjustable versions. The non-adjustable are more common.

Great, thanks for the info. Ill have to do some more research to figure out if these are for me or if I should sell and put towards a complete setup.
Looks like the spring is 750 in/lbs, 6" length.

Does anyone know how much these are worth? Thinking about listing and picking up tc kline or GC setup as I would prefer a more track/street friendly setup.

Without knowing the condition of the internals I'd say ~$450-$550

I may be wrong, but those look like ground control coilover conversion parts that were added to the dampers afterwards. Is there a bolt that clamps the lower spring seat around the threaded sleeve? I don't really know the group N parts, but I am on my second set of ground control springs and seats.

Yeah I was about to say, those look very similar to my Ground Control coilovers with the exception of the camber plates and the different strut housings. The height adjuster definitely looks like Ground Control, and they also use Eibach springs just like that.

Thanks for the responses. I'll have to check out the shock seat and report back.

So they are group n but for some reason they put ground control sleeve and perches on them. When I pulled it apart and removed the ground control sleeve, the original threads of the coilover are still there.
