I’m looking at picking up a used set of GC’s for my car, with the hopes of eventually pairing them with some Koni Yellow’s, better tires, and bigger sway bar’s. I would like to go auto-x the odd time, but mostly street duty.
Anyways, I looked up the part numbers from the springs, and came up with this:
First of all, should there be two different lengths of springs?
Second, I’ve read that factory DA suspension is set at 250/150. This setup would give me 330/250, which is stiffer, but would it be enough?
Would I be able to swap the springs front to rear, and buy a stiffer set for the rear? Like say, use the 330’s up front, and buy a pair of 400-450’s for the rear? Or would the front not work with the 7" springs?
1)The springs are supposed to be two different sizes.
2)This depends on what kind of ride you want. Your best bet would be to try taking a ride in an Integra with those spring rates (or close to) and see how you like it. Its all personal preferance and its application.
3)No, you cannot switch the back to the front and front to the back. First off because as you mentioned, they are different spring lengths. Secondly, depending on which springs, some are made to have one end reduce size and these are usually front/back specific.
Hope I helped Dustin.
If I gave any wrong information, feel free to bash/correct me.
My only other question is, am I correct in my assumption that the higher spring rate is for the front? I’m pretty sure to get a set of GC’s with higher rear spring rates than front would be custom ordered, and the seller I know didn’t do this.
The only info I had read previous to this on spring length was from this FAQ , which says the only difference b/t 7" and 8" is that the shorter springs can obviously be used for a lower ride height (which I don’t need), but it sounded interchangeable to me.
However, if they are made a certain way for the front and rear, then I guess I won’t mess with this and just run them like they are.
Well, Ground Control springs are made by eibach as coilovers, not set springs. Im sure you know the difference but if not the answer can be found by searching.
They should not be ingtechangeable. If the suspension componants were the exact same front and back, than maybe, save for the different spring rate. Since their quite far from eachother, it just isnt possible to interchange them. I have seen a few threads on this matter on this board from people who accidently but the front in the rear and rear in the front, which gave them an odd looking stance and all around muched up suspension (rightfuly so :P).
From what I understand, the higher rate springs should go upfront yes. My sugestion is that if you dont have the oppertunity to drive a car with similar spring rates, compare them to other well known and reputable springs with similar spring rates and see what people had to say about them.
You will notice a larger difference with different shocks rather than different springs. My suggestion is to put the springs aside until you have shocks to go with them that can handle the ride. You will have a lower ride height, but there will be no difference when taking corners as to how well the car stays down.
Hopefully soon I will have the same suspension; Koni Yellows, GC coils and top hats, and camber kit.

This is exactly what I’m planning on doing. Too many guys buy a set of cheapo eBay coilovers, drop the height 3", and then blow stock shocks right away and have brutal negative camber that leads to immediate tire wear.
I won’t bother putting them on until I have EVERYTHING (dampers, springs, camber, tires, possibly sway bars) as a package.
And for a little off-topic, I picked up a pair of Fat Fives today, so now I’m down to only looking for 2 instead of 4!
Well I picked these up today. Now, the set I bought didn’t come with any ‘top hats’, so if I use stock dampers, do I just re-use the stock upper mounting stuff or should a new set of GC’s come with some?
Also, when switching to a Koni setup, what exactly do you need different to allow you to use GC’s with them?
You can reuse your stock top mounts. I believe GC’s for Koni’s are different than GC’s for stock shocks or Tokico’s. Not sure what’s differenct though.

Can anybody tell me the differences? I was under the assumption that it is only a different top mount that they provide. Here is one comment I found, but this is from an E30 BMW M3 application:
"GC also provides custom made rubber pads to use where the small spring contacts the upper spring perch."
