Will the ground control coil over part number 4530.01 fit a 94 integra. In the box it says the kit fits a 02-00 civic but just want to make sure i can put them on my car, and i didnt buy them i sold some parts and got cash and the coil overs. thnx in advance.

For 92-00 Civic, should work on Integras as well.

 

Sweet what about the stock shocks with the ground control coilovers will that work also?

 

They will fit, but it will be pure crap.

I would not recommend anything less than Tokico Illumina shocks for standard GC coilovers. Anything less just cannot withstand the high spring rate of adjustable coilover suspension, and the typical ultra-low ride height. Koni and Bilstein are good choices, also, but you will need GC sleeves specific to each of those shocks for them to work.

 

Do you by any chance know what spring rates you have? I wouldn't reccommend using the off the shelf spring rates, they are a little too soft for an Integra. If you can, let us now what spring part numbers you have...

 

You mean Civic OTS rates, right?

If I got GC's again, I would go with 380 lb/in 8" front springs (what I had before), and 350 or even 300 lb/in 7" rear springs (had 450 lb/in rear before, MUCH too stiff for daily driving).

 

unless you are lowered to the point of having no suspension travel left, 8" 380 lb front springs are too short

 

Ok they have two set of numbers the first ones are (front) GC200.64.58 / Eibach springs 209794 (rear) GC180.64.44 / Eibach springs 235587

 

340/250spring rates, very soft, not recommended for your car. Rears are ok but may want to bump the front up.. Just an idea, most would also bump the rear up also..

 

If you're thinking about coil bind issues, there won't be any on an EG/DC.

00 GSR running 8" 400 lbs/in front springs. Stock upper mounts, shock would bottom (full bumpstop compression) before coil bind. GC extended upper mounts, and the UCA hits before full coil bind.

I almost wish the spring would bind first. Almost.

 

Doing some quick math here:
An Integra weighs about 2700 lbs, with 63% of the weight on the front. That means each front wheel supports 850 lbs. The front motion ratio is 1.5, so that means the force on the spring is about 1270 lbs. For a 400 lbs/in spring, that will compress it by 3.2". This 8" spring, according to Eibach, has a stroke of 4.7". But you've already used up 3.2", so you only have 1.5" left till coil bind. This means that you have 2.3" of wheel travel till coil bind. That's not a lot.

On my car, I currently have 10" 425 lbs srpings on the front, and the front is lowered by maybe 1/2-3/4" over stock. Running the same calculations, I have 2.6" of shock travel until coil bind. Which is kind of good because I see about 2" of bare shock shaft and then a bumpstop. So at full compression, I'm dangerously close to coil bind. I have an additional 3.9" of wheel travel left, which looks about right since I'm not even close to tucking the tires.

I think the actual numbers will come out a little more generously due to geometric considerations and etc.

 

haha don't rely on math so much man, rely on how it works in the real world.

When I had GC's, my front end looked like this with 205/45-16 tires:



I had 380 lb/in 8" front springs. I had no problems with bottoming out (there are no dents in my shock towers), the GC perches were maybe half-way down the sleeves, and the spring was nowhere near binding up.

The tech at GC recommended the 380 lb. 8" spring for the front of my car. I believe that's what comes in the Integra OTS GC setup.

But regarding your math, are you sure the motion ratio affects how much weight is really on the spring? I can't remember if it does or not. *starts visualizing in head* Think if the spring were mounted all the way out at the end of the lever arm (the lower control arm). There would be a motion ratio of 1, and that 850 lb. corner weight would compress the 380 lb. spring 2.25". The end of the control arm (and the wheel) would move up into the fender 2.25". Now move the spring up 1/3 the distance of the control arm (approx. where it is actually mounted). The 850 lb. corner weight should still compress the spring 2.25", but now the wheel should move up into the fender by nearly 3.5". At 2.25" compression, the spring would still have nearly 2.5" left until coil bind, or 3.75" of travel at the wheel.

Hell I dunno if this is right, just trying to visualize without having something physical to experiment with.

 

in that picture, how much wheel travel did you have left.

See here for a calculation:
https://honda-tech.com/forums/suspension-brakes-54/worried-about-coil-bind-2062714/

The motion ratio acts as a leverage to put more force on the spring, just like a nutcracker.

 

So thats what i have right? and what springs would be more appropriate for my DC2

 

okay I see how the calc's work now.

In the picture above, I know for a fact the suspension would either hit the bumpstop or upper control arm would hit the shock tower before the wheel moved up another 2.3" (point of coil bind). There are no dents in my shock towers, or marks on the underside of the shock towers, so I know that my 8" 380 lb springs never reached coil bind.
