I'm looking into some GC/Konis w/ a 400/500 rate (rear biased)

I've searched and read great praises w/ regard to this setup. Can anyone provide a contra-argument as to why a front bias (ie stock) would yield greater results in auto-x?

I'm looking to pull the trigger on this setup, the car is a weekend warrior, and will see some auto x duty this summer.

Any input is appreciated

 

Thats way too soft.

If you are going with Konis for AutoX then look into the SSPS3 valving and get the highest rates you can stand. Or go with the race versions, there skews are: 80411152front 80411164rear

 

My last autocross I was Koni/GC 500F 450R. My times got faster everytime I softened the front. I like front bias for anything faster than autocrossing, but I should also mention I have a Mugen 26mm rear swaybar. Since then, I put a spare set of 450's up front and was 450/450 for a while. Now i'm on stock springs as I drive my ITR most of the time. Still have that 26mm rear sway. This was on 215-45-16 Azen1s

My 1st autocross ever, I was able to pull 2nd place in my class with cut stock springs up front and Mugen N1 650 rears, along with the 26mm rear bar. This was on crappy Parada Spec 2's

 

This car will mostly be driven on the street w/ occasional track duty. This may be a bit aggressive? Also, do you recommend the front or rear bias?

Sounds like you've done well w/ a front biased setup. Most JDM setups lean towards this route although most U.S. auto-x'ers I've spoken to swear by the stiffer springs in the rear

 

I also prefer it like uiltraspeed does. I like a soft front and stiff rear. I also use a Mugen 26mm rear sway bar to help with this. I like my car to almost instantly "lift oversteer" when I lift off the gas pedal. It gives maximum rotation in tight places but it does take some getting used to and never ever hit the street while using those settings. It could get ugly real quick.

 

Well, I'm on ~700/900 with a Mugen 26mm rear sway. For street tires that seems about right, but if I were running R-comps, I'd significantly increase the front rates.

400/500 will work fine, but don't get too aggressive with the lowering or else you'll be on the bumpstops quite often, which isn't good--at all.

 

That's the problem, this isn't a track only car. Sounds like a front bias, w/ a JDM rear sway may be a good mix for a street car w/ occasional track use

 

Sounds like a winner.

 

Anyone know if the spring lengths are different for the front and rears on the GC/Koni setups?

 

i perfered front bias spring rate and use a sway bar to tune in more rear roll stiffness. I felt that it offered better ride quality for daily driving.

During spirited driving rear bias with spring rate offered quicker response to rotation and more progressive.

I was running Apex-i N1 8k front 6k rear with JDM 23mm rear swaybar.

Overall spring length is the same with GC/KONI

 

Started autoxing my R for the first time since i bought it and I got 3rd in class!! Im on koni yellows and stock springs. The only problem i noticed was trying to rotate the back end. Its a jdm spec so my sway bar is 23mm? It could use some stiffer springs rates and sway bar. IMO I would get stiffer in the rear but not much.

 

usually 8" front, 7" rear
If u don't need it slammed, get both 8"
than you can swap F & R around if u want to

 

just a note
ITR stock spring
F linear 250 lbs/in
R progressive up to 250lbs/in
(EK9 CTR same setup but w/ 240lbs/in)

w/ the motion ratio & doing the math
you will find out stock ITR(DC2R) & CTR(EK9) Wheel rate is rear biased as well

 

Anyone know if there's a difference between 94-01 Integra Koni/GC's and 98-01 ITR koni/gc's???

I sent a pricing request to a sponsor and got a response back implying all years use the same setup. I thought this wasn't the case?
