Non-koni GC sleeve to be installed on a Koni
Yes, they are Honda Civic GC for non-koni shocks.
I was just worried about the O.D. of the Koni, but I was pretty confident they would fit.
Thanks for confirming it.

The only safe way to run GCs on Konis is with with the Koni specific GC sleeves, or the Koni adapter for standard GC sleeves (which I don't think they make any more).
Normal shocks mount the spring perch directly to the shock body.
Koni Sport shocks (Yellows) use a groove in the shock body, fit a circlip into this groove, then lay the spring perch over the circlip. For the circlip to stay where it needs to, you need to load that spring perch correctly. This is why GC makes Koni specific sleeves...
Wait, didn't you ask the original question?
Anyway, this has come up many times here on HT, and the answer has always been the same from Koni, only use a sleeve that was intended to capture the circlip, never use a sleeve on top of the Koni spring perch.
Anyway, your car, your money, your life, do as you please.

I don't get why you would ask a question and then turn around and be the expert with someone who's trying to help you.
The obvious thing to look at would be why would they make a 'Koni-specific' GC if the regular ones were just as reliable and performed the same. That's your answer.
Just becase you CAN eat Raviolis out of a flip-flop doesn't mean it's the best and most efficient way to get the job done, especially if there's a Ravioli specific bowl available for your eating needs.

Oh and to make this thread constructive and helpfull, GC does sell the Koni adaptors to make any sleeves fit...

Anyway...my money, my life, my car and my dumbness were you saying. Thanks anyway.

Really, all you need is an adapter that slips OVER the circlip and presents a FLAT surface for the sleeves. Then something that keeps the sleeves centered if they are a loose fit. I've made adapters for my Bilsteins that have the same circlip groove mounting system.
Tuner is right, DO NOT use the spring perches designed for springs with a cut end, as that will not present a flat surface for sleeves to rest on.

I can't say I've never been wrong, as I certainly have been, and will be again in the future. But I can say that while I try to provide correct information, its still on the reader to verify it, trust it, or ignore it (your choice).
I've tried searching, and can't find a good thread discussing seating a threaded sleeve on a Koni's spring perch at the moment, but I'm also trying to get out of this office and go home so my heart isn't exactly into it.
*edit: You have "thanks Lee @ Koni" in your sig. PM him and get the final answer.

Basically, the GC sleeve can put uneven pressure on the perch/circlip and cause it to separate from the shock body. There have been a couple members over the years who have had the circlip fall through, causing the entire corner of the vehicle to slam onto the bump stop.
Here's more:
If you as using a threaded coi-over sleeve perch system, that system must also fit properly and have a groove in the bottom side to perfectly capture the circlip. Do not put a grooveless coil-over sleeve on top of a KONI grooved spring perch and hope that it holds up. The sleeve must fit right and have its own groove. To my knowledge, only KONI and Ground Control make sleeves specifically grooved for KONI circlips. In 12 years of working for KONI, I have never seen or heard of a truly well fitted grooved coil-over sleeve system or spring perch ever fall down or fail but I have heard of plenty of ill fitted or improperly installed ones fall down. The system is very strong and allows adjustability that a welded perch does not allow but it must be used correctly or it is wrong and at risk of problems.

I have a question about this as well. I am running non-koni GC's on my koni yellows.
Not sure if you guys will understand me exactly, but ill give it a shot.
The circlip has a metal ring that goes over the top of it. The rings inside diameter is the same as the shock, but extends out to provide more surface for the sleeve to sit on. Does this come with the konis or ground controls? Could it be some short of adaptor? I cannot find pictures of one online anywhere..

Unless it is the Koni supplied spring perch you are talking about, that sits directly on top of the circlip, in which case you have a failure waiting to happen on your car.

the way the gc koni perch is made it would keep the snap ring in a uniform position thus keeping the perch on the shock if there was uneven pressure it would be possible for the snap ring to fall off infact likely!
If you run the non specific sleeves on the OE style perch this will void your warranty. Since those adapters might be discontinued I would tell you to try the skunk2 adapters but that would probably void the GC warranty.
Also, if i buy new sleeves do i need both front and back?
