CAN97SH

Weaksauce is a good person to speak with and yes he apparently can get you a deal.
He's on this forum I think. Cant remember his ID though.

I bought my stuff right from Ground Control.

mherkamp: so if I convert to a manual rack then the power steering issue is solved? Does this disable anything else that I might want? I'll look into it more as Im sure there are a ton of questions/threads about it

A modest 440fronts and and 380 rears. It honestly is so balanced and easy to manipulate through corners. Feels more like a rwd car imo.

Okay. Thanks. So these would be the ones to buy, to match up with gc coilover sleeves, correct? Without getting custom rates, that is.

tclmember

Also, would I need to use oem top hats? or what's a good top hat to use?
Sorry if this is a dumb question.

CAN97SH

The rates I have are custom rates. They dont cost anymore to order.

I like the rates. They can be a little hard on the road at times. Going over railroad tracks and whatnot. I've bottomed out a couple times in the front but thats probably because my rates are not super stiff.

There are no top hats you can buy for our cars. You would have to custom make them.

^^CAN97SH here is the link to how it has been done in 4th gens, 5th gens should be similar. https://honda-tech.com/zerothread?id=1517004 Basically, you take the rack out, dissassemble it completely and pack it with synthetic grease. Mad props to all involved in this classic write-up, esp. mgags7. I can vouch, been dd'ing this mod for almost 2 years and no issues. I don't miss ps at all, and as long as you are moving AT ALL it isn't hard to steer. Most of the time I can't even tell.

So OEM tophats it is.

Is it still possible to get custom rates, if I purchased from an authorized dealer, for example weaksauce, instead of GC themselves?

See, the problem is, I can't know what rates to actually use, since I've never really rode on any other suspension other than stock. I just want to avoid bottoming out, but still be able to go pretty low. So I'm assuming I'll be needing a little bit higher rates than yours?

CAN97SH

You are awesome thanks. Now to decide if I dont want PS anymore

I was in the same boat as you. Everyone was. Unless you know someone who has this setup you will never know until you get the setup installed on your car. That's why I chose the rates I chose. I didnt want something too harsh for DD.

If you want to go lower then yea I would get higher rates. The koni yellows without the revalve can handle 600 I think. Someone correct me if Im wrong.

I would think weaksauce can get custom rates.

tclmember

Very true, Could you estimate the drop you have on your car?

And yeah that's what I was thinking. Maybe like 460-480 in the front/400 rear. perhaps.

I hope so. I wonder if they let me buy them in store.

CAN97SH

I would say an inch, inch and a half? It's about a two finger gap from the top of the tire and the bottom of the wheel well.

I would possibly even get stiffer than that but your daily road driving and your ***/back might suffer due to the stiffer rates. Thats all relative. I read about people saying that their 600+ rates are not harsh at all. I think they are just trying to be a badass cause that has to be back breaking, especially on rough roads.

tclmember

Hmm okay.

And perhaps 500f/450r. Hopefully It comes out good. I just need to see if weaksauce, or the other place I could get the gc fora bit cheaper, will allow me to do custom rates.

typemismatch

This is interesting ... I'm enjoying reading this. [no sarcasm intended]

If I were to answer what rates to use I would say much higher, 600+ front and 800+ in the rear.

Why the difference you might ask?

I weekend drive and drag race my 'lude.

You'll notice my rear rates will be higher in the rear than the front, this is to help with launching and 60' times.

This is one of the reasons I warned about taking people's opinions over personal research.

I do want to mention, if you buy a setup and don't like it, you can always sell it and buy something else.

CAN97SH

Good advice. People use higher rates in the rear at autox events to produce more oversteer.

Like I said, its all relative. I have spine problems and having the rates you have would break my back. Literally

If the OP's car is for DD then those rates would suck imo. Too harsh for me

typemismatch

Yeah, since it my weekend car [and it sits in storage for the winter], it doesn't really matter to me.

If I were a truly twisted individual, I could've told him super high rates and defended them with pseudo tech and kept him in the dark until he bought them.

But I'm not, I'm more interested in seeing him get what he really wants.

tclmember

Makes complete sense. I've actually thought about that. Having stiffer springs in the rear for more traction in the front wheels. I've always noticed when watching videos of cars taking off they burn all this rubber, cuz the front is lifting up.

But if I choose those rates, won't I need uh I think the term is "revalving" or something like that for the shocks to handle that? I'm actually in contact with a person here selling the combo for 880 shipped, and I just need to figure out the rates. gives me a better idea of the numbers I should pick thanks

typemismatch

Forget revalving ... if you chose those rates for a DD you'll need ... a new spine

From what I've read, ~600ish lb limit is comfortable for Koni yellows to handle like CAN97SH commented. I tried to call Koni and speak to a tech rep, but they were closed...eastern time owned me.

It would be nice to have a few other prelude members chime in with their spring rates to help you out.

Right now we have:

CAN97SH (track/DD) - 440FR/380RR
typemismatch (suggestion for track/DD) - 600FR/800RR

and found this...

https://honda-tech.com/forums/suspension-brakes-54/koni-yellow-ground-control-spring-rate-2668224/ --- might be helpful

cullylude05

Koni yellow/gc for maybe six years and around 100,000 miles no problem yet, I can't think of the spring rating but when I called ground control I was still alittle unsure about what rates I wanted. Lucky the guy on the phone had a few question for me, to work with me on what would be the best setup. I've been very happy with it. I'm using this on an SH too and so he knew also that base to SH is different from factory.

cullylude05

I liked using ground control, because they have everything on record and I had to order two of the black polyurethane rubbers, umm cant think of the correct term but it's what the top of your spring sits on and goes against the top of the strut tower. They took care of it and had it to me in a couple of days from like CA to Alabama. They said to glue them to the tower b/c mine would come down with the spring when u lefted the car up. Over time it deatroyed the rubber urethane piece. Payed a grand for my setup.

tclmember

I should call and ask and see what they recommend. Should I call GC or Koni? and Yeah I'd like a few to chime in. I'll be looking over that thread pretty soon.
THANKS!

tclmember

So way out of the question then.... lol

cullylude05

Call the company ground control 530 677 8600, they sell the setup with koni strut and eibach springs. U can buy right from them they do the setup. Just call and tell them what your plans r, what u have base/SH or whatever. And your plans with the car, they will help u with the spring rate and if the guy or the phone doesn't seem to be helpful. Wait and call back. B/c they been great the few times I have called

tclmember

Well, They sell them a little more expensive than a sponsor from here on HT. I might just call them and ask for suggestions on spring rates than tell the vendor I'm buying from the rates.
Thank you very much!

OP, I have the megan ez coils and I'm droped a decent amount they arnt to bad for dd but iv also been getting into auto x latly but they are decent for the price I have only had them for about a month now and no problems.

tclmember

Sweet, that's good. IDK was never really considering megan, But I truly appreciate the input, hoever

h23bb1

No problem, just thought id throw in another option for ya. I never really thought about getting other brands I got a deal for the Megans so I took them. But there are a lot cheaper coils that are just as good, as stated by pervious member's. Good luck with your decision
