I'm about to buy a set of Konis for my 1991 Integra, and I need to know if there's any valving differences between the DA/EF and EG/DC over-the-shelf versions of the Koni Yellows.

 

You should get the right parts for your DA: 8041-1200Sport front and 8041-1201Sport rear.

The DA dampers are not only longer in max and min length to fit the DA but they also have one step more compression damping front and rear then their counterparts of the EF, EG, EK, and DC. There is a little bit more low speed rebound on the rear as well. if you were to put the Sport dampers from the otehr cars on your car without revalving them, you would be going to a softer valving and different spring perch locations even though you are getting a shorter body shock. this would not be a good idea.

For some pure race track only DAs that sit very low with zero ride and long term livability issues, we do have some folks using the EF or EG/DC 8041 RACE series dampers. The EF RACE front bodies are really much shorter than the DA Sport at 4 1/2 inches shorter at max lengths (nearly 7 inches at the wheel!) and 4 inches shorter on min length ( about 6 inches shorter at the wheel). The EG/DA RACE are about 3 inches shorter max and min at the shock but require a larger ID front lower mounting fork.

So if this is for a street based, not ultra slammed racecar, use the proper DA Sports for the car.

 

They're going on an STS Integra.

I'm on Skunk2 coilovers, Tokico Illuminas, with Ground Control mounts right now.

So even though the EG/DC Konis have larger shock bodies, and more fluid, they're still not valved as stiff?

That is correct. There is slightly more compression damping all around, the same front rebound damping and very slightly more low speed rebound damping on the DA units than all the other related EF, EG, EK, DC dampers.

The piston and body diameter sizes are the same, the DA units are longer and thus have more fluid (which means nothing). If this is a very serious autocross car that is lowered quite a bit and not used much if at all on the street, they you might consider using the EG RACE units (8041-1152RACE & 8041-1153RACE) requiring an EF/DC front mounting fork as that much, much more aggressive race valving will handle and control better at the sacrifice of ride qualtiy and harshness for use on less than smooth surfaces. If this is a primarily street car that gets used fairly often for autocross, I would use the correct DA Sports (8041-1200Sport & 8041-1201 Sport).

 

Okay, I just realized that the two sets of shocks I was looking at were the 89-91 Civic set, and a 94-01 Integra set. Both being the same price, what shocks are the better shocks?

The ones that fit your car. They are the same quality, essentially the same valving so get the ones that are dimensionally right for your car.
8041-1200 Sport and 8041-1201 Sport

 

Front shock forks can be changed, that's not an issue. The newer Integra shocks will fit fine with those forks, and the 89-91 shocks will fit without any changes. Coilovers will get rid of any problems with the spring perch height.

EDIT: How much longer min and max are the DA shocks?

 

currently i run, DC koni sports with GC coilovers and custom spring rates (550f 600r)
on a DD autox car. and it works dandy for me, but when it comes to koni products CRX Lee knows what hes talking about, if i was buying brand new i would for sure get the DA shocks, but i picked these up for real cheap and i plan to get them revalved and shortened for my application and spring rates anyway

 

Unless you are getting an absolutely smokin deal, why don't you just listen to Lee and get the proper shocks for your car?

But if you must choose between the two, I'd get the 89-91 Civic shocks. Yeah, you can run the 92-95 forks, but they are longer and will cause less shock travel if you lower the car.

I already gave you the length info comparing DA Sports to the RACE shocks for the others. Comparing the DA Sports to the other Sports, the DA fronts are about 3 inches longer in max length and min length than EF fronts and about 1.5 inches longer in max length and about 2.5 inches longer in min length than the EG/EK/DC fronts. On the rear, the DA units are about 1.25 inches longer in max length and about 1.5 inches longer in min length than the EF/EG/DC rears.

Also, realize that you will have no warranty if you put shocks other than the DA Sports on your car. I have now spent over 30 minutes at work to research all your data and spent plenty of time repeatedly giving you information that you asked for and advice that you don't seem to be interested in heeding. This is my last post on this thread. You're welcome.

 

I think I should have been more clear, I found two sets of shocks locally for sale. One set is for a 94-01 Integra, the other is for a 89-91 Civic.

If I was going out to buy brand new Konis, I'd buy the 90-93 Integra, Neuspeed versions. I'm a little scared about lowering the car too much, because the DA shocks are so much longer. I had a travel problem with stock mounts, and it would be a complete waste for me to buy the longer DA Konis, only to have them revalved and shortened, which is not something I plan on doing. I only will run OTS, because I don't have the extra money for a race version.

As Lee said, it isn't the length of the shock necessarily...it's the location of the spring perch. He's given you all the answers--you just need to put them together.

Either way plan on running adjustable coilovers because lowering springs won't make the car sit correctly on non-DA shocks. And your Skunk2 perches probably aren't going to work with a Koni shock. You'll need to call Skunk2 and get adapters--if they make them.

 

I'll be making my own coilover perches if I decide to keep my Skunk2's.

 

Wow Lee, your a pretty patient guy!
Don't think I could have been that patient...

 

Finally found the part #'s off the ones I'm buying locally.

Yes, I am... They're part #8041-1152 Sports.

I still don't understand how spring perch height is going to effect ANYTHING when I have adjustable coilovers. So if the shock spring perch on the 8041-1152 Sports is say, 1" higher, then I lower the spring perches 1" and everything comes out even.

Like I said earlier, I have the Ground Control shock mounts because I was running out of shock travel. I don't want to put on a set of longer shocks only to run out of travel again.

The Race version Koni Yellows are out of the picture at this point, because I don't have enough money to buy those. I should have defintely been more clear about that.

Also, like I said... I'll be making my own spring perches if I continue to run Skunk2 coilover sleeves, but I'm looking for some used GC sleeves and Koni adapters.
