GC Coilover Spacing Ring - needed?
Hey gang,
I was going through the rear suspension on my FC last night in preparation for an event this upcoming weekend. I am running the GC coil-over kit with KYB-AGX shocks in back. I noticed that the o-ring that makes a spacer in between the collar and shock body has broken on one side (it fell out while I was inspecting the shock). The ring on the other side wasn't looking too good either.
Has anyone else seen this happen? Are there any recommendations on how to replace/repair the rings without having to pull and disassemble the shock? (I'm thinking about a few turns with some duct tape... ).
Any advice would be greatly appreciated.
Thanks,

Contact GC for spares
I'm sure they will hook you up fairly. I live about 2 miles from them - they once rebuilt two of my AD shocks in 45 minutes and didn't even charge me (I was going to the track that day). Jay is a righteous fellow.

Well, they are "true" coilovers in the technical sense. They just aren't as pretty as the integrated units, nor do they have as many adjustments. But they are cheap and they work. In terms of how well they work, I think that's more dependent on the quality of the shock that is used. Right now I have inexpensive single adjustable AGXs on there and that's good enough for me at this point. In the future I may upgrade to a better unit, but for right now they are certainly not the limiting factor in my laptimes.

Springs are cheap - swap them in/out as you like. One warning though. The KYB AGX reaches it's limit with around 400 lbs/in springs. Anything stiffer and the shock just won't handle it. 400 is what I run in front on the track car.
If you are gong to go stiffer, you probably want to start moving up the price scale and looking at something like Konis.
Good luck,

I do not like the AGXs with the GCs (380/325) on my Vert. Too much high speed compression. They crash over bumps hard. If I could do it over again I would go Koni or AWR Bilsteins.
As for out-of-the-box coilover vs. GC/damper combo: How much do you want to learn and how far do you want to go? OotB coilovers will be nicely constructed but will limit your growht in understanding and changin the parameters of the damper/spring setup. With the GC/damper setup, you'll have to learn about how the damper and spring work together, but the performance ceiling is much higher.

You can get the Koni's revalved but it would need to be done by a Koni approved service center. It costs about $100 a shock IIRC. The problem with trying to go beyond the regular valving on the Koni is the actual size of the valve, it is just too small on most of the street adjustables. When you get into the double adjustables there is usually enough range to handle about any spring you would want to run unless you go crazy.
The Bilsteins you can usually find a circle track shop that can do it for you.

The Konis I listed are both double adjustable.
The Bilsteins in general are not adjustable, they have some adjustables but you need to do some engineering to use their stuff on an FC and I don't think they have strut inserts that are adjustable. That said any of them are revalvable if you know what you are doing so whatever fits in the gap you are trying to fill can be made to work. They can also have remote reservoirs put on them. At this point you are getting far away from a bolt on application and a shock dyno is needed to know what you have built.
I was headed down the Bilstein path for my race car when a good friend asked, "So, you're going to pull the shocks off at the track, revalve them, test them, re-install them and then go run 4 or 5 laps to see if what you just did worked?"
I have a shock dyno so that wasn't the problem, I have Koni's with strut housings that I made with some GC coil over parts I got off another forum. A few clicks and I'm back on the track.

well i'm talking about a full coil-over conversion that they have for my car. They gave mr an estimate and the total was 1800 and some change. But it was designed for my car but the stance GR+'s are cheaper and i can get a different spring rate from "Swift" springs for like a $150 extra.

There is no comparing the Advance-Design setup that GC will make (which BTW is an "integrated" setup, which I think is what you are calling a threaded body damper) and a brand like Stance. AD is the real-deal, competitive racing ****. Stance is just another copy-cat street coilover. I'm not saying they suck, but it's like comparing a sprinter to a marathon runner.

i see but i think i'm still gonna lead more to the GC and the fact that they actually make it for the specified application is pretty damn cool. i guess ill just piece it together and have them make a custom mount for the strut with the koni's. That's if they can let me peice it like so. but thanks for all the info guys
