To start off, I have already read a few threads about spring rates for the GC/Koni Yellow's combo.

For the ride, i'm looking for a comfortable Daily Driver with a nice drop. This ride's probably never seeing the track. Based on my research a good Rate would be approximately f350 and r250. Normally i would just shoot the gun and get those rates, but i want to do it right and get more specific on what spring rates to get. I've seen variations from 400/300 to specific as 380/241. Now I wanna know what you guys think what spring rates i can get, what sounds more reasonable for the ride i'm looking for. As for my drop, I'm just getting rid of wheel gap. Right now running 195/50/15 tires on kosei k1s. so probably a 1-2 inch drop. Right now stock suspension. adding just a front strut bar soon. GC will be combined with Koni yellow sports.

Gladly will provide more info for more helpful inputs. Help a honda fellow out. Tryna do it right.



Edit: I already called GC and the guy told me to ask Honda-tech. I thought that was kinda funny, but I'm sure you guys have good inputs.

 

im running f450 r400 but i also plan to attend a few autox events but mine is also a daily driver so i went for more of a middle of the road deal and im also driving a ek sedan

 

or should i say ej6

 

Comfort is purely subjective. Sorry to say you can ask 50 people what their idea of comfort is and what rates to get and none of them will come close to your idea of comfort. If you think stock of comfortable then the logic that slightly higher rates should yield a comfortable but firmer ride then go with the 350/250.

With these things it unfortunately a trial by error thing.

 

With 350F/250R, how low can it drop? I would like to have two fingers gap between the tires and fenders for my EG hatchback..any suggestion(s) on the spring rates?

 

lol thanks for the input negusjuda.



grumblemarc, I do understand that it's subjective, but was wanting to get as comfortable as comfortable gets. in other words just get opinions. And yes stock is comfortable, but only thing i get to compare to is aftermarket/replica coiloversleeves+stock shocks. I am looking to get 350/250 in which i believe is kinda common. but i want to ask you (cause you seem to have been here awhile) what's been a good rate for you? Is 250 in the rear to soft? i'm leaning towards maybe 350/280 just cause its a passenger car(loading people). if that'll even make a difference.

As you can tell, im not too familiar with suspension. just know not to cheap out. Progress CSII seems to have good reviews with the 350/250 street performance. in which leads me to that rate.

 

MugenEg, 2finger gap i dont think is much of a drop. which means you dont have to worry about rubbing. More info though would allow people to help. i.e. rim size, tire size. cause you could be running big rims/tires and rid of that gap. (not that you should)

 

i had H&R sports on my 96 4dr and I think they were about 330lbs. it was a decent ride, a bit on the soft side. If I did it again I would go a little higher. Probably 400-450f and 350-400r. I prefer a somewhat firmer ride over comfort

 

yoitspbj, I'm running on HX wheels (14") and sprint hart cpr 15 x 6.5 with 195-50-15 tires. But will mainly run on HX wheels. How far on koni yellow with groundcontrol coilovers can it drop with stander springs (not custom)?

 

350/250 is terribly soft. I'd expect a mild drop. much lower will bottom out all the time.

If you want to have 0 gap or 1 finger gap you really need 450F/350R at a minimum.

 

Alphalanos, thanks for he input. Just to clarify for myself firm doesn't mean bouncy right? Bounce would just come from stiff springs and maybe soft strut or in some mismatch of that sort?


Mugeneg. You're looking for daily?? Track?? Ridding of wheel gap? Wheel tuck?


Thanks Libertariate. Maybe ill consider somethin firmer. 400/300? approx. I see you're selling your progress csII auto cross series 350/350? Not lookin to buy but Were they too soft for you?

 

After 2 full seasons of racing I've simply outgrown the cs2. Still a great performer and can handle a solid drop. Pictures of my car are in my build thread.

 

350f 250r is a bit soft for a sedan lowered more than 1". I would say 450f 350r is a much better starting point for a moderately low DD that gets driven spiritedly.

 

I'm riding on 350/250 and I would NOT say that they are soft. Definitely unsuitable for anything more aggressive like Autocrossing. Firm would be the word I'd choose and those rates are fine for a 1.5" drop. Couple that with a beefy swaybar in the rear and you have a solid handling vehicle.

But you know what? All this is totally subjective. Suspension has been a trial and error process for me over the years. Rarely are you going to get it right the first time out.

 

Spring rates are definitely subjective because some time ago when I asked what was tolerable on the street people said higher that 300LBS in the rear is very harsh. I lost sleep after ordering 450/400, no seriously I lost sleep thinking oh man what did I do? I put them on and then became mad that they weren't stiff enough lol. I'm remedying that with swaybars in the future.

 

Libertariat, if youre using 350/350 for track hows 350/250 too soft, and recommending 450/350 for daily? sounds like a stiff rate. just wanted to clarify that. really diggin your build though. your ride looks like about 1inch finger gap, is it? well, looks good. Oh and i got a chance to skim through your suspension thread, real good information, unfortunately i didnt see it before i started this but thanks for your input anyway :D

FlewBy, 450/400? sounds real firm for a daily. wanting to go even stiffer?? you might need an $1000+ setup cause yellows arent supposed to support 500lbs/in+ rate righ?? correct me if im wrong. anyway i understand its subjective. sounds like youre probably a stance guy and is dropped to the pavement and needs the stiffness. cause if you really like 450/400. you must hate stock at 165/80 progressive.


Really odd the differences being posted coming from 450/400 - 350/250. maybe ill choose something in the middle like 400/300 or 380/280. thanks for the inputs. hope this helps someone out there as well. Keep posting for more opinions on your suspension!

 

Maybe you're not aware that he selling those? That's how he's recommending it. And it says PLAINLY in his sig "daily & mid-level autocross". For his requirements these rates ARE too soft.

And the differences are there because it's SUBJECTIVE!!!! What part of that are you not understanding? Are you ignoring everything in this thread that isn't specifically giving you spring rate recommendations?

 

haha my mistake youre right grumble. but doesnt justify recommending 450/350 at a minimum. since he rode 350/350 autocross.

 

I take offense to that! **** no I'm not gay stanced and slammed bullshit. I was actually at a 1 finger gap and raised it to a 2 finger gap with 23.2" tall tires because that low on those rates was detrimental to handling. My jacking points are at like 5.25" in the front and 5.75" in the rear. Everyone keeps telling me to lower my car or get coilovers. I just shake my head because I'm not on some regular drop springs, I am on coilovers which are actually preloaded to give you an idea and lowering the car rode fine but handled less than ideal.

 

He's been saying that for at least a year now. Maybe longer. But how does it not? That's why he's upgrading because 350/350 is too soft FOR HIM.

 

i understand its subjective, but point of thread is asking for specific rates and opinions on those rates. i know i know, trial and error process. but why not get suggestions and ideas from others trial and error. i get it. subjective
thanks grumbles.

 

My seats are carbon fiber backs and bottoms too... no complaints with 450/400. In fact my friend just purchased the same rates for his EM1 and he has no intentions on making a racecar. Just a car to cruise around that rides good.

 

I don't think YOU'RE getting it. Pick a rate. 350/250. You were already told by two people that they were soft and just right. You can do that for any set of rates you imagine and still get the same kind of answers and NOT come any closer to them helping you make a decision. Another set of rates 450/350. Some say that's a good starting point, others say too hard and other say too soft. It's like friggin' Goldilocks and the Three Bears for Crissakes!

This is no different than anyone else that comes along thinking that what they are asking is somehow different than what the last guy asked.

 

And the entire time I rode 350/350 autocross I wished I had 450 or 500 up front for daily driving.

It wasn't that the soft software rates were good for the race track. The soft rates were on purpose so I could learn how the car handles at the limits. Now that my driving skill has graduated above those rates I'm getting a stiffer setup to go faster.

Trust me, I listened to a bunch of old wise guys in picking my setup. Learn how to drive your car before you turn it into a race car. Learning how oversteer and understeer work is almost impossible on the setup I'm going to be running.

 

450/300 for a DD.
But that is very subjective.
