So I called Ground Control....
.... and asked what the spring rates were. The very nice gentleman on the other end of the phone was kind enough to tell me.
375 lb-in FRONT / 425 lb-in REAR
(Rob add this to the FAQ)
I told you all something you didn't know....
Now someone tell me... do you reuse the dust boots with them? Or do they not fit inside the spring. This applies to front and rear.... I need to buy new **** since I don't have any or my OEM stuff anymore, so I'm trying to minimize what I have to buy to just what I have to have.

Rep Power: 424 There's no difference. The difference between the 2 kits is the rear collars. GC designed a set of collars to fit right on the koni snap rings vs. the rear perch on the OEM shocks. That explains why sleeve kits blow shocks so fast... those are pretty hard springs.

First of all, yes, they're pretty stiff. I could have fixed this probably relatively easily, new springs, which I did once already. There's absolutely nothing wrong with them, they're great coils... definately designed for heavy track use, and they work like it too.
I went for konis and GCs for a couple reasons....
I like tinkering projects, which building my own coilovers pretty much is.
Second, I wanted something that could be serviced quickly and easily, revalved or shortened if necessary. I'm going to have the car for quite a while, and I plan on continuing to beat the hell out of it on a regular basis. In the event I break something or need to make changes, Koni has lots of places around the country that I can send them and get it done quickly, JIC does stuff slow, in Japan. Takes longer. While I don't anticipate them ever going, I'd rather have the more conventional and more widely used setup among the track crowd... it increases the liklihood of someone knowing how to fix a problem on the fly.
So did I jump on the bandwagon persay? Yeah, kinda, but I did it for the help of common knowledge and the ease of replacement parts down the line (you can buy 1 koni easily you can't get 1/4th a coilover kit). I'm gonna be selling the JICs... so someone's gonna get lucky and get a real clean set for a pretty good price.

Rep Power: 417 how much? how bout free for a fellow mod? 
hopefully your getting stiffer rear springs though.
I had ground controls(granted they were on stock shocks) and I thought they were the worst suspension ever.. bottomed out and bounced everywhere. handling sucked(although it was probably cause I didnt use the stock bearings)

Rep Power: 424 Oh yeah, I custom ordered stiffer rears.
PM me, we can talk if you want, but its probably gonna be about a month... I doubt free.

Spring rates & unknown motion ratios
I might be missing something, but these look like reeeeeally weird rates to me. I've looked at a bunch of civic spring rates and the rear to front spring ratio is around 2 to 1, because the rear spring is mounted on a levered arm and moves a lot less than the rear wheel. The GCs ratio is about 1.1 which looks very odd ie way stiff on the front and not stiff enough on the rear. In fact, the rear even looks too soft relative to the front for an RSX or SI, which are heavier cars and seem to have rear/front ratios around 1.8. If the rear spring/rear wheel motion ratio is something like .6 (saw this on RSX board and it seems like it might be close?) then the rear wheel rate for these GC springs is .6 squared times 425 which is 153, a whole lot lower than the front at 300+. It sure would help to know the rear wheel motion ratio...
Zzyxx, you've been looking at this, does this look right?

Rep Power: 424 Well JICs came with 500/560, about the same split, they tore around the track just fine and well balanced. You have to set the whole car up. I did order mine with a little more rear bias.
There's always room to play with it.

Rep Power: 0 Yeah, I agree. Seems to me I was looking through some suspension book and the rule of thumb to have the rear wheel frequency a bit higher than the front, for ride comfort, goes out the window with substantially higher rates.

Rep Power: 0 k, gotta a question...I took my car to get my GCs installed and the shop said they wouldnt install the GCs without a bearing (the part highlighted in red) that would fit the GCs springs?????? huh...Is there even a GC bearing for our car that you can buy? he also said that if i did install it without the bearing my steering would be all Fuked up..?

Rep Power: 0 well i got em installed at a different shop (Defcon-Racing, for you Toronto folks) and they did a pretty good job so far, feels like a brand new suspension set-up, which i guess it is...although i did get new konis up front too (i blew one and were bought used, so no previous warranty)...and about the bearing problem, they made it work, i forgot to ask how or what...but its good...
