After installing some ground control sleeves on the rear of my 87 crx I discovered that the stock rubber mount was pushing through the rubber donut allowing the spring to pass up into the shock tower of the frame.

Am I missing some adapter plate so that the spring doesn't pass through the rubber donut?

Yes .RJ I will be calling ground control but I want to know if I did something wrong or they forgot to ship the adapter plate.

 

What I had to do for the coil-over arrangement at the rear on my prepared 86 Civic was fabricate a steel plate in the shape of the stock rubber mount, with a concentric hole large enough for the upper shock mount to go through, to give the spring an upper seat to sit on. This was for a Carrera threaded body set-up.

I would think GC would offer a more elegant solution than what I came up with as described above.

 

Well, it's a little more elegant than that. Basically you use the GC sleeve upside down from what you would be used to in most other coil-over conversions. The spring sits on the lower perch, then the threaded sleeve with the 'upper' mount sits on that, and you need to cut the metal cap out of the old stock shock cover and put that in the top of the GC sleeve. Essentially the sleeve is what goes up into the shock tower, not the spring.

Does that make sense?

 

rpr, I see what you're talking about but my Koni shocks were shortened and customized for sleeves. There is no longer a perch for the spring to sit on.

I was planning on making a metal plate like preparedcivic said but I was hoping that ground control made a nice billit aluminum adaptor but I guess not.

 

We've got a billet alum. spring perch for 2 1/2" or a 1 7/8" depending on which way you want to go. The 2 1/2" fits in the same place as the oringinal or the 1 7/8 goes all the way up into the shock tower. It depends on how much spring you are going to run.
IM and I'll be happy to help you out.

So you really need a lower spring perch? I think I still have my stock Koni lower, if you still have the spring clip on the bottom you can have them. If not, then you will need to use a smaller ID spring most likely. I used a 2.25" ID spring and it fits right inside the shock tower. Not sure if it's the best way to do it, but it works. Or like has been mentioned, use some kind of plate to sit where the stock rubber mount normally sits. I know of one guy who used a kart wheel chopped in half.

 

Update:

Just ordered the bullit aluminum upper mounts from Walt at Delta Group Motorsports. Excelent service and knows exactly the part I need. This is one of the reasons H-T is so kick ***.

I did try calling Ground Control to see if they had just forgot so ship the part and the guy on the phone didn't know what I was talking about and the person who should know what I'm talking about was out and I was told to call back later. Ground crontrol forgot to ship my sleeves for a week when I first ordered it and now it seems they don't know that their product doesn't fit.

Yeah, this is exactly the same thing I did on my '89 Integra. I did put a small bead of silicone on the metal cap that fits on top of the GC sleeve, to keep it from rattling loose when the car was lifted. Before I had to be slow and gentle while lowering the car back down to make sure the spring lined up correctly with the upper perch, etc. But now no problems.

 

Here's a pic of the billit aluminum Delta Group Motorsports spring adaptors that are a must when using GC sleeves.

Very yummy. If you don't mind my asking, how much were they? I'm tempted to get my machinist to make some for me, but if they are cheaper from Delta...

Thanks
