Default Ground Control Spring Rates

I am looking at getting a set of GC's to go with the Tokico shocks I just bought. Really I am trying to set the car up for every day driving, and an auto-X every once in awhile so I dont want to go too too extreme.

Just curious what sping rates you guys who were running GC's or any aftermarket spings for that matter, and how you liked them

I would also like to know. I was thinkin bout getting liek 400 up front and maybe 350 in the rear. I need stiff springs cause i have a lot of extra weight (turbo/stereo) and it is pretty low. My DP is pretty low so i cant have it givin too much. What r the Max springs rates for say Koni yellows before u have to re-valve? And u think the proposed spring rate sr stiff enough?

PS. i have eibach prokit and theyre too soft Sorry if im jackin ur thread.

i was wondering the same thing, does anyone know? Also from my understanding GC offered 3 different spring rates, 1 for KYB AGX's, 1 for Tokico, and 1 for Koni yellows. Does anyone know how much truth there is to this? If so, does anyone know their respective spring rates?

For a daily driven car I would not go over 400lbs/inch.

400lbs/inch in the rear and 350 front should work rather well. GC offers any spring rate you want, just tell them what you want

Cool, thanks for the reply. Do you happen to know what stock sping rates are? I just want something to compare to.

what are some possible spring rate setups to get neutral or even a slight over steer out of a prelude. I see this topic covered all the time in the Integra forums but never suspension setups in the prelude forum

Put the 450's in the rear, and put the 350's in the front. The car will handel better that way. the front and rear springs are the same size so it will be ok to swap them. Our cars like to understeer, so to help fight this you will need higher spring rates in the rear than in the front.

No way. You knw how light *** of the lude's are? Ive got a lot of weight in the front of my car so thast why i got some extra sticck springs in the front. Also im on my 3rd downpipe. I keep ruining them from them scraping. No way im puttin 350's up front and 450! in the back.

I didn't know your goal was to keep the front from scrapping, I thought you wanted the car to handle better, my bad.

what he is saying is not altogether false though. i have gotten decent rotation by merely fudging with tire pressures on stock suspension.

put the 450's in front, the 350's in the rear, and take off the front bar.

That's what i did on mine (although mine's a 3g, and it was 400 in front and 350 in the rear.). It's quite nice. Plus, it keeps the front bar from unloading the front inside tire on turns, so you can put more power down coming out of the turns, AND you won't have to worry about scraping!

Default Ground Control Spring Rates

Hey I am planning on buying Koni Yellow shocks and ground control coilovers for my 97 Prelude SH. It's a daily driver and I don't plan on Auto Xing it much, but i still would like to rip through the backroads where I live. I was just wondering what spring rates I should specify to gc that will allow for daily driven (all seasons) comfortability and really good handling at the same time. I'v heard that you shouldn't put stiffer springs in the rear because the rear is so light as it is, and I'v also heard of guys running stiffer springs in the rear and saying it causes better neutral handling and oversteer (and at the same time it causes the back to drift more easily). What do you guys suggest?

i have owned a crx and now i am on to the prelude read plenty on this topic from the pro in auto-x to know on honda you want more spring rate in the rear to cause slight over steer to swing the rear around maybe you guys could try 300 to 350 front and 350 to 400 rear for everyday driving.

I daily drive, ~80 mi/day, on 450F/375R; I wish I had listened to the people on po.com and gone higher with 550F/450R. This is with konis, lowered an inch or two (I was too excited and stupid to measure before), and in the Chi-town burbs. Anyone know the 5th gen's stock ride height?
