Adjustable Coilovers vs Spring/ Adjustable Shock/Strut

ok so first off yes i searched and found alot of good info but it wasnt really helpful enough for my liking. it was alot of useless opinions with a very little amount of facts.

This isnt really based on price so please that isnt a factor in this thread. so i have been looking at spending a good amount of cash on my suspension starting on the springs and shocks/struts.

i have been researching information on alot of diffrent sites and from many sources but would still like some good input for this site since it has the best people and information for my s13.

now heres my personal situation. ive tried to buy coilovers 2 times now and it just hasnt happened. first time it was because the seller of the D2 coilovers couldnt get them shipped to me in a reasonable (45 day) time frame so he refunded me my cash. the second time i was going to buy megan racing coilovers for 900 shipped on ebay which to my knowledge is the best deal out there other than a groupbuy. the seller on ebay "found a flaw" with my set so he refunded me the money also. this has all made me reconsider my choice and rethink the spring/adjustable shock route.

my car is going to first and foremost be a daily driver but i do like to drive my car hard. There is a possiblity of track/drift sessions so adjustability would be VERY nice for that but i dont see that happening just yet. i dont plan to complete in either autox or drift so i wouldnt be out trying to win a thing, just learning. now i know i sound like i made my mind up but heres my pro coilover statments. a good spring/shock combo is going to run me within a few hundred of a decent coilover setup "like the ones ive tried to buy" so that leans me towards the coilovers again. plus i dont want to be re buying parts down the road either.

though i dont see me adjusting my suspension very often while daily driving this car. i do understand the coilovers would be help me find my "prefered" driving setup. in order to fully use the coilovers im going to need a few other adjustable parts like adjustable RUCAs, toe arms, torque arms and some tie rods which i would like to have but i dont see me using them to their full potential either. i also dont see me paying for a race shop to adjust these parts since most alignment shops are incompetent.

ive had a car with kyb shocks/struts and intrax springs that i daily drove and i didnt mind it at all but ive never driven a car with adjustable coilovers. the stiffness of the ride has no effect on my choice. its just about the handling and practicality of the setup.

so with my total situation on the table, please can you guys give me some good advice and possibly personal experience with your suspension setups.


ohh ya sorry for the book.

I was also thinking about buying coilovers for my 240 when I do my suspension upgrade, I was leaning toward tein... But I talked to a guy who said that the coilovers had to ruff of a ride for everyday driving, but would be good if you were serious about dirfting...So he switched to the KYB AGX struts(which are 10 way adjustable) and the Tein springs(rated at a 1.5 inch drop) and said that its a great set up...This is what im leaning towards now...I think the total cost if bought on ebay is around $500 or so in all...

I have been in a 240SX with coilovers, and one with shocks/springs and I believe both had adjustable RUCAs. Now, you're always going to have a tradeoff between ride and handling, but some are better at both. The coilovers felt barely stiffer (they were set on a low dampening rate) than the spring/shock combo, but handled a decent amount better. Also, most coilovers have more adjustability in terms of hieght and dampening, so you're going to be able to find your "sweet spot".

So it basicly comes down to you get what you pay for. Coilovers are a little more expensive but I think it's worth it. I also believe that you'll need RUCAs and the other suspension stuff just as much with coilovers as you will with spring/shocks. Hope that helps.

Well there are many different type of full coilovers. Rough ride or not. Most of these suspension are made strictly for track use. Some people that track their car and daily drive it just has to deal with a rough ride.
When someone judges a suspension setup by "ride comfort" is plain dumb. If you want ride comfort, why not stick with stock suspension?

If you want best handling, get coilovers. If you want comfort and halfass handling, get struts and springs. It's as simple as that.

I got used to my tein coilovers. Everyone that gets into my car are shock about my ride comfort.

just to clear things up, they arent 10 way adjustable. they are 8 in back and 4 in front.

i have agx/sportlines. on the stiffest settings they can get pretty stiff, but ive never been in one with coilovers to compare. if i had the money id go with coilovers, but my car is more of a budget deal than anything. im happy over all with how my car handles tho. im finally starting autox in a couple weeks and i feel confident in their abilities.

so ive done alot of thinking and came to the conclusion that COILOVERS are going to be too much for me at the moment. i was thinking about the number of times i will probably track this car within the next year which is no more than 3-5 times. i dont think i will be adjusting them very much if at all so im going to go with AGX and a spring setup. i do really want coilovers but i think i want them at this moment more for bragging rights rather than for the adjustability.

as my experience driving my car on track increases and i learn exactly what needs to be changed based on my driving style is when i think ill go with the full adjustability i need to do that. also this car should turn into more of a weekend/track car as i modify it and it becomes less "streetable" since i already own another car.

thanks for the input and more info in this thread will help others out so ill make sure to reply back with my experience!

I would go with koni's over agx and rsr has way better spring rates than tein. most people just want the jdm bling even though they really don't know how the suspension feels. I'm not knocking jdm products at all, just get the most for your money. It really depends on how much money you have. And just to let you know, if you get some dope $2000 coilovers, the high spring rates will eat up the shocks with everyday driving. cheap and reliable and comfortable vs. expensive and fast and a rough ride. I know this dumbass kidd with an 88 integra with cut springs and the shoks lowered as low as they can go. That is a shitty ride. I've rode in cars with many different coilover set ups and most aren't bad at all, similar to a stock 350z.

i dont know where i came off as being concerned with ride? honestly i dont really care about the ride of the car because like you said its a 240sx plus i live in a area with really bad roads so im used to bumps.

my first and only concern about my suspension is PRACTICALITY. price was never really a concern of mine. im not building a car based on what i can afford at the moment. i did this with my last car and learned my lesson very quickly when i ended up with a pile of junk with junk parts.

if a 2000 dollar set of coilovers was my best option and most practical for me its the route i would have went. since i dont need the adjustability of coilovers right now i dont see them as being practical. this isnt just a random thought about buying suspension parts for my car. ive combed these boards and google for months and months reading people experiences.

i have read some books based on suspension geometry and have been attending local open lapping days at my track. ive talked with alot of people about suspension setups. the most common response from the veterans there was too stay stock while you learn. after i explained my suspension was shot since its 15 years old and most likely original they said go with some light mods like performance shocks/struts, possibly lowering coils and strut braces.

so my final conclusion was that COILOVERS are out of my league until i get some experience under my belt on the track. i know for a fact that this year i will not make it out to the track enough to get a good feel for what needs changed in my car to suit my driving needs. so like of said before coilovers will not be a very practical route for me until farther down the road plus 500ish bucks on springs shocks and struts is next to nothing when it comes to modifying a car. after i use these for a year i know as long as they are in ok condition i can get atleast half of what i paid for them back by selling them. as bad as it sucks 240sxs' are overly popular with young kids and they are very free with there parents money..lol

i didnt mean to come of as a dick so if i did please dont take it that way.

thats cool. But I'm not sure what you mean that the coilovers are out of your league. For me, money is an issue so I'm gonna try and not have to buy another set of anything, I might as go for broke the first time around.

If I were you, and I'm not, it's just a suggestion, I'd just get the Coilovers now. Even if you don't make it to the track, it's WAY more adjustable then the KYB AGX and in the end it's better quality. Don't get me wrong I had KYB AGX on my eclipse and loved them!! But if money isn't an issue, HECK, go get Kei Office or HKS coil overs, something with adustable ride and damping and call it a day. That's just me, no sense in getting the shocks and then realizing "hey I want to drift" and then have to get coil overs.

Good luck with the Car. Much respect.

out of my league means that im still learning how to tune suspension setups for grip, drift and drag since coilovers are highly adjustable i wouldnt put them on my car without the other supporting mods ie adjustable tie rods, toe and torque arms, RUCAs, camber plates and a good suspension bushing set. im not ready to dive into that kind of adjustability just yet with my car. if i went that far i would want to take it to a race shop and have the suspension professionally tuned for my driving style which i dont really even know what that is yet.

i dont see it as 1500 for coilovers then picking a ride height and dampening setting then be done with it. in my opinion thats not what adjustable suspensions are about but its what most people do. that to me is a waste of money. i dont believe most people really even know what the effects of adjusting the aspects of your suspension are. ya ok negative from camber is good for handling thats well know but how many people walk around with the theory the lower your car the better it handles? thats so very untrue.


on another note i went ahead and ordered my new parts today from ebay. i went with KYB AGX and sportline springs. i dont know what my camber is going to be like after i install these so im going to hold off on the camber plates until i have it aligned. im going to try to stay near factory specs for the time being.

i also ordered cheapy ebay front and rear STBs that i believe do that same job as 200 name brand bars but we can save that for another thread.

now my next purchase will be front and rear sway bars but i think i will be going with whiteline adjustable bars because i feel my understanding of how the diameter of the bars and the adjustments affect my handling is good enough to propery use them.

get MR coilovers from underground motorsports.
"to harsh" is relative to opinion, but most people feel that shocks and springs don't do the job for any kind of track car.
if you want just low stance and aren't concerned w/ body roll/handling, get shocks/springs. or i believe tein has some coilovers that have height adjustability and aren't that "stiff".

p.s. 8kg/6kg springs aren't that stiff, imo.

im guessing that you didnt take the time to read the above information. i agree with you that coilovers are the way to go on a track car but that is not the basis for my choice of suspension components.

i stated above that you tune your car based on your needs a driver. since i am a complete beginner to the idea of autox and tuning a suspension for my needs, coilovers will cause nothing but problems. it will be much more simple to learn my style of driving then begin to adapt my car to it rather than building a car and learning to drive it. if the time comes to switch cars that i would want to autocross, i will have a defined style of driving that can be applied to any car.

the outstanding reason im even buying suspension parts is because my stock suspension is shot and seems to be the original suspension. i decided that if im going to go through the trouble of replacing the shocks and struts why not go with something better than OE equipment. 550 dollars on shocks/struts and springs is hardly a sizeable amount of money when it comes to tuning a car.

P.S. stiffness of the ride is not and never was a concern of mine when it comes to the components i chose.


if i came off as a dick again, i didnt mean it. im not trying to justify my purchase because to each there own. im just trying to put coilovers and suspension tuning into persepective for people that are looking for information on it. alot of people want coilovers but how many can actually explain the aspects and effects of tuning a suspension. not too many people i know. :thumbsup

I bought my KYB's and EIBACH's to replace my OEM parts and it worked out well. I really like it. My friend had TEIN coilover's and I liked it but I didn't think it was good for a dailly driver. When I asked him about it he agreed and said he would have preferer to use the KYB setup I have. It is fun to drive and at the same time comfortable on the road. Not meaning it isn't bumpy but around certain corners on rough roads the car won't hop. I would just buy the Damper and springs now. Get used to the adjustments buy the other adjustable components like Toe and Camber etc. Then later get some coilovers and you can switchout between road and track. If you ever start to feel as if you don't want to use the dapers any more just sell them to some body else.

twofortySX, well...let's see...you did come off like a dick, but only b/c you're speaking directly about what you want and why.
i'm glad you're thinking things through. since stiffness isn't a concern, i still suggest the KYB gr-1's and sportlines. it's a nice drop, slightly (very slightly) stiffer than stock, and for you're needs, it'll suffice.
i don't think you'll have any complaints about unless you want adjustable dampening, which of course, would point you to the AGX's.

oh, and no i didn't read your entire post up top

Modacar. It was on clearance for under $600. I've seen it for even less though. After I bought it I was so mad. lol, patience is the key to shopping. I guess I'm the typical guy. It was appealling so I just bought it. But I am very happy I did. I've had it for more than a year and it is good to me on the mountain and on the street everyday.

I got the Tein S-Techs on mine, stock shocks. I'm saving up for new shocks/struts, though. The S-Tech is a bit bouncy, and I feel like I'm on a trampoline.

TwoFortySX, I like the way you're thinking. Kind of a... getting your feet wet first type of thing. Personally, if I wasn't on a minimum wage salary, I'd probably do the same.

hey man, i think you made a good choice. i suggest also looking into sway bars. your setup is looking very similar to mine, and so is your reasoning. the only difference i have is the ST sway bars, and im quite pleased for the amount of money ive spent on my car.
