hey hows it going i have an eg hatch dumped (oil pan inches off the floor) with koni yellows ground controls 350f and 2..r spring rates and my car is really bouncy. i took out the bump stumps and cut out my shock tower so my camber kit doesnt hit. i dont know what spring rate to get. i want a really stiff ride. i was panning on getting 900f spring rate but people are telling me that i cant go higher than 500. so i dont know what to do. i need you guys opinions and help i would greatly appreciate it
Thanks

900lb? Are you crazy?

The koni sport is rated to 600lb, however, you can run higher spring rates on it. It's just not reccomended.

Oh yeah, it will always be bouncy.

doood

how about you raise the damn thing? anything over 600lb on koni's without having them revalved is a bad idea.

Kozy.

Your rates are too low for that ride height. You obviously don't care much for handling, ride, comfort or anything other than the looks, so go ahead and drop 900s in.

MonkeyMagic

did they say why?

and then i must ask why to both questions. not trying to ruffle feathers but i gets old hearing false accusations and regurgitated internet "experiences." there are many dynamics to suspension design, such a vague statement is ridiculous. furthermore, some people.. actually, a LOT of people like low cars. in fact it could easily be considered a staple of most any automotive genre. although, and the honda world is still poking air-ride with a proverbial stick. so until the honda world figures air suspension out we'll continue to see lot's of silly spring rates.

THIS is the only way the op will be able to limit his suspension's travel over normal bumps and humps on the street.

i can tell you that you'll need to turn the koni's all the way up and still expect to be launched into the air over some humps, to the point of having your seat belt lock up. but it'll keep your fenders with a clean radius.

personally i don't thin 2" from the ground necessitates springs that high. idk, depend on your roads and how you drive.

i want a nice ride where i cant feel the bumps on the road without having to raise my car. i plan on going lower as well

koni themselves recommend revalving or using the race model yellows with rates over 600lbs

wow

This will never, ever, EVER, EVER happen....

Kozy.

Yea, sump scraping, limo smooth ride. Just like that supermodel next door who does your cooking, cleaning and brings her supermodel friends round for weekly threeways. Keep on dreamin' pal!

if your serious about this, then what you want is air-ride. put enough air in it to be around stock height while cruising, then air it out when you are parked or in 'look at me' mode. it's the only way to go low and have a decent ride.

you realize that a car smooths out the bumps in the road by allowing it's suspension to sink into the car as it goes over that bump. if you use a spring which will make it more resistant to allowing the suspension to compress, it'll make the car move more over the bump (stiff spring), and send this movement right through your *** and spine. you cannot have a good ride and keep your oil pan from becoming a sparkler while lowered on anything involving springs.

i can assure you they don't so point blankly. it's internet myth that stiff springs will cause damage to your shocks or otherwise induce armageddon. (that koni did tell me over a phone call i made to them quite some time ago, i've been working with them a lot on the latest project lol) on a track vehicle up around 1000-1200 lbs/in it's pretty much a guaranteed. but there are a lot of things dependent on this, vehicle weight, purpose, etc. and a street car with 600-700lb springs is just going to be a stiff, bouncy, shitty ride no matter under or over damped.

in so few words.

lmfao

i dont care if im bouncing i just dont want the car to bounce. right now my car feels like a bounce house on any little bump and its annoying to drive. im not going on bags because bags are gay and they are for cheaters and plus im not a volkswagon lol

Bustin_Hatch305

all i want to know is what would be the perfect set up for me with having to raise my car

98civdx

What the **** are you talking about? You don't care if your bouncing, but you don't want the car to bounce?

MonkeyMagic

ok, your dumb is hangin out... might wanna tuck it back under the seat of your pos honda.

is this really how kids think these days? **** me, we're all doomed. volkswagens are not the only automotive genre on the planet to use air suspension. why? because it works. you were smart enough to buy koni's, be smart enough to realize it's not the perfect solution to what you're looking for. anyways, here's your answer:



read your post again, you already typed the answer. or read the sticky in this very forum.

The Hire

Agreed...


Also if your not going to mostly drive the car to and from the race track.... an uber stiff suspension can be down right dangerous on the highway.... Cause race tracks don't have dips, humps, bumps, waves and holes. I've seen a purebread track car go airborne and land the next lane over on the highway when cruising at a good clip and hit some wonky pavement. Lucky the occupants wern't killed.

There are good reasons people make compromises when building a car for both the street and track.

Bustin_Hatch305

can someone just tell me what spring rate i should use holly ****

98civdx

This is what happens when your posts don't make sense, and you expect amazing ride quality from a slammed car..


550/450.


/thread.

The Hire

LOL... Sorry man but there is no black and white answer. I spent a month or two reading and asking and thinking what I really wanted to build the vehicle for before deciding on spring rates. ****.... I don't buy a set of tires without spending at least 20 to 40 hours reading about them on everycar forum on the planet.


I would say for what your using the car for, ie not tracking it, pure daily driver low and slow, not interested in spirited driving... a good balanced base line would be 300lb linear springs front and back...

As soon as you biasing the spring rates front or back, you start adding oversteer or understeer, and a lot of that has to do with driving style, personal preference and the type of motorsport you want the car suited for.

You can't build a car to be good at everything.... Always tradeoffs and balances. My car has riduculous throttle response, acceleration and some oversteer. In the tight confines of urban streets its a rattlesnake that no exotic could match. On the open highway, I top out at 140mph and just about every basic OEM euro car could outstretch me.

So go do your homework... search and read.


Good luck.

300lb is not enough for a slammed car.

You have to worry about bottoming out the shocks, and keeping the UCA's out of the shock towers. Higher spring rates are needed.

The Hire

Ahaha.... Your right... Somehow I got this thread mixed up with the "anyone tried these yet?" thread... Lack of sleep.

Thanks for correcting me.

Ill shut up now... lol.

98civdx

I do it all the time, I'm runing on 3 hours of sleep. lol

my advice is to either deal with a harsh ride, because thats inherent to a lowered car or go purchase a luxury car. take your pick, those are really your only choices.

Dont feed the ******* trolls guys, just leave this one to die.
