I called ground control and they said you don't need have have Koni yellows revalved for 400 and 500 pound rates... Is he right??? cuz if I dont have to I
rather not pay a extra $100 a shock!

btw he said he runs 600lbs and has no problems...

Thanks for any advice!

The only parts that you left out are what the car is and how you use it, the two most important parts of the question. Generally you'll probably be just fine with the existing valving and adjustment range. It may not be the ultimate valving for racing or autocross disciplines but it will certainly be better than any other option out there. Nothing says you couldn't have them revalved years down the road as you develop the car further if you are going into competition.

 

oh sorry, my car is a 2000 Honda Civic SI with 15x7 Kosei K1 and Falken Azenis used for auto-x and road racing... But also drivin on the street, but not as a daily driver!

 

Not necessary, but your handling will improve greatly if you do.

 

Oh

 

I work at Ground Control and all of our cars are daily driven, even the almighty E46 M3. You could deffinately run a 500lbs. spring with the Koni Yellow's. Just don't drive hard and dumped everywhere.

 

I use the 400/500 with OTS konis right now. Ride's great, handling's great. Just about a perfect match I think. I need more spring though, so I'm going to 600/800 and using the off-the-shelf jobs until I get a set of the revalved konis. We'll see how it goes.

 

i ran 400lbs srpings with my ots konis with zero problems. used it for track days and DD.


Its turned out to be a nice set-up for the street/track.

 

I ran 450/600 on Yellows. Felt great.

 

Thanks alot guys for the info!!! I'll stick with the koni yellows without revalving and if I decide to go with bigger spring rates I'll revalve my shocks at the same time!

 

Coming from a rear wheel drive car (and a lot heavier one at that) looking at your spring rate numbers it looks so "funny". So I take it you are talking about 400fr/500r which dials out understeer and gets the car to rotate on turn in. Correct? I am in need of some srpings and on the car I just sold I ran Konis/GC sleeves with Eibach ERS. I need to buy some springs on the Civic CRX/B18c I just bought for road course work. Pardon the "newb" post but I have a lot to learn pretty quick in that I have an event coming up in may and have a lot that needs to be done to get ready. TIA.

Yea 400lbs in front and 500lbs in the rear!

 

ive got GCs with 500f/400r with Yellows and they work like a dream. all i do to get rid of the understeer is stiffen up the rear konis and problem solved

 

In my experience the OTS yellow valving was not quite adequate to control 550lb. springs on the front of an 89 Civic. Instead of revalving, dropped the rates to 450 and it now works like a dream.

Had ProParts revalve the rears "as far as they could" and they handle 600lb. springs nicely.

Not that I have personal experience in these spring rate ranges yet, but if I were looking at a shock to properly dampen a 750+lb. spring, I'd pass on the yellows and look to a 30 or 28 series.

 

Sorry but whats OTS??? Stand for?

 

"Off The Shelf" or stock, with the valving as it originally comes from Koni.

 

here's an old email I dug up:
btw: this is when I emailed Koni about some information.

>Can you please provide me the maximum spring rate that can be paired with your
>Koni Sport Adjustable shocks for an 94-01 Acura Integra?

It's usually recommended that you have the shocks revalved when you go above 400 lb/in (about 7.1 kg/mm) as you'll have very little if any adjustment range left (it does depend on the driver though).

>Would I be able to use them with a set of 10k front, 9k rear springs?

I'm assuming you mean 10 kg/mm front and 9 kg/mm rear. For those rates, I would look at getting the shocks revalved. If you have any questions, please write back and let me know. Thanks for writing.

Oh thanks for the info!

 

listen to CRX Lee, he work for koni-usa

I believe this to be true and CRX Lee has told me/us the same thing. I'm currently running 500f/600r on OTS Konis and it feels good to me, but everyone has said that the feel will be much better after a revalve at the same rates.

The response that Gordon from Koni (my employee) gave is correct but extremely conservative as one often needs to be on out of the blue emails. There is no hard definition of "this will work and this won't" as on spring rates and valvings because there are simply too many variables and personal preferences. As soon as someone gives a number, other poeple will chime in and say "this worked for me" or "this didn't" just as has happened in this thread.

I probably have more Honda and Koni experience than anyone and have talked with literally thousands of people over the years about this. Unless the spring rates are really huge, if you are trying to start your street with occaisional competition use car and money is a little tight as it is going together, then I suggest starting with the off-the-shelf Koni Sport. The stock Koni is still has more capability, range, valving, etc. than any other OTS performance shock out there and you can always have it services later if you decide you need it.

If it is a pretty dedicated racecar or highly developed, compromise acceptable street/track that is being throughly done with the expectation of competing at a high level and you have the money available for the added service, then a revalve will be good to strart with.

In a recent thread, I used my mid-'90s high mileage, warranty bin refugee Koni Sports from my street CRX with 400f/600r springs recently for a day of track flogging and they did great.

 

thanks alot for the info Lee

 

When people say's revalving the Koni,does that mean it will now be compression adjustable and the piston rod will be bigger?

I'm just about at this point myself, but am planning on keeping the 400/500 for a little while longer.

What I have found with the DC2 chassis (and I DD it) is the combination is enough to make the chassis "fatigue" over time. I've been patching this with various bars and the like, and so far...am pleased with the results.
