If i choose to just only buy the lowering srpings by themselves will that give me garbage handeling in comparison to right now?...or cna i get away with it..im only looking to drop my car 1.5" at the MOST...i just dont want the performance to be affected that much you know...so is this ok to do..what would u suggest...need help on what to do...1000 for a while suspension kit...or just go with the lowering springs...thanks in advance

EDIT: I just keep seeing a lot of their Eibach lowering springs for sale...they sound to be pretty decent and they say they are compatible with stock shocks and that...

just need help with this and what choice to make..thanks

i have eibach sportline (1.8f and 1.6r) or something very close to that, and i have stock shocks. ive been riding on them for about 10 months and i have no complaints. the ride is definitely stiffer, but very tolerable. i probably wont replace shocks anytime soon unless they start leaking.
(by the way my sig is without the drop)

I probably would only go Hand R OE springs with the stock shocks.
Lowering without aftermarket shocks doesnt handle that well.

hmm ic ic ... do u have any pix of ur car with the drop..mine is 4 door as well..just wanna see how it looks...also..has ur handeling worsened since putting them in...thats my biggest concern...WILL I LOOSE HANDELING WITH ONLY PUTTING LOWERING SPRINGS FOR A 1.5" DROP??? :confused:

100% YES to the point of being dangerous. The ideal setup is a softer spring with a lot of dampening. You're going the exact opposite route. Do not stick lower, stiffer springs in there without the correct shocks, or I will come and eat you.

o really? wow...so then what is my best bet to buy an enitre kit? they go for about 1000 o my

well i definitely feel that my handling has improved. i dont track my car as of yet so for street driving i feel it is suficient. a spring/shock combo will definitely be a better choice, but im kinda low on cash.

ill have pics in a couple days

Just wait until you take a bumpy turn at a good clip. Hope you got a good bodyshop.

Suspension work is not cheap. Do it right or do it not.

You don't want to spend $1000 on the only parts connecting you to the road, but you have easily at least $2000 in cosmetic mods planned in your sig?

Ah well, we're all guilty of losing sight of the important stuff once in a while ;)

they will work with stock shocks. there will be no danger other than damaging your suspension components, and it may be a bouncy ride, but definately you can do it until you can afford to buy shocks as well.

I give up, do whatever you want. Just cut your stock springs down, save even more cash and you still get that hot dropped look.

^ I know its not the *right* way to do it, but it works. Im not arguing with you, and agree that if possible you shoudl do all at once.

Yes you will handle worse, yes you will put a lot more wear on suspension components. But if look is what you are going for, and in the end will eventually upgrade all necessary parts, its really your own problem if you do it or not. Just drive your car carefully, dont push it..and you will not be a danger to others on the road either.

Don't take this too personally but that's as stupid as having a cardboard steering wheel and saying that's not a danger to anyone on the road if you just drive carefully and don't push it. Like Chris Rock says "just because you CAN do something don't make it a good ****en idea". It's time to grow up, you're not playing with toys anymore. If you **** up here you will do a LOT of damage, and not just to yourself. There are professional engineers whose sole job at an automotive company is to get it right with the very thing you are shrugging off as if it's upgrading your stereo.

Here is a quick physics lesson. When you go over a bump with a wheel, the spring in that corner gets compressed and stores potential energy. This is then released as kinetic as the spring straightens, pushing the wheel back out. But due to conservation of energy, it will do so further than level for your car, but to a smaller degree than the wheel was pushed in (due to losses). But since the wheel sticks out more than the others (and a few other reasons I won't bother with - just covering my ass for you physics guys so you don't lynch me :)), it will be pushed back by the weight of the car, and this process repeats, until through various losses, the energy in the system stabilizes back to normal again. This is called oscillation. To control oscillations, we have dampers. What these puppies do is with every stroke, they will resist the movement, making the energy loss drammatic. Therefore, the stronger the damper, the more energy will be lost (by that I mean absorbed by the damper) and the quicker the oscillation will stop.

So knowing that, think about what you're trying to justify. You're taking a damper that was designed for a far longer stroke (more time for it to work on each one) and a lower energy spring, plus the damper is probably half dead or all dead, and using it with a short, high performance (read: high spring rate - that potential energy bit above) spring... What does all this spell? Next time you're taking a corner, and you hit a bunch of bumps, you're gonna be hopping up and down and if you happen to hit several bumps in phaze with the oscillation you already have, boy you are screwed! You will end up with wheel hop and you will go off the outside of the turn. Another example. You're bootin' along the highway, and you had to scratch your ass or look at some sexy cows or whatever, your attention was diverted, and you didn't see people stopped infront of you and you have to perform an emergency stop. You slam on the brakes but you hit a series of bumps. Guess what's gonna happen? Yup, wheel hop. And stopping doesn't work very well when you're wheels are off the ground most of the time. So what will happen is you're eating bumper.

Still sound like a good idea? If so, I repeat, I give up. If not, I reiterate, this is not upgrading clear corners or your stereo. You're ****ing with a seriously complex system that was designed to work as a unit, and MUST be treated as such when modified.

And by the way, knowing the above, now you may understand why stiffer springs aren't all that important for high performance. It's more desirable to have a higher damping rate than spring rate. It's perfectly fine to have a softer spring and a stiffer shock, but it is not, to have it the other way around (which, as I've illustrated, IS dangerous).

BigD, i respect your knowledge bro, everything u said in ur post is true. But personally i also think the age of the car also matters, or specifically the age of the stock shock, given that the driver is not a reckless mainiac (speeding thru bumpy turns :P). i have a 2002 and im running eibach springs on my stock shox, and till now there are no hints what so ever that im could "wheel hop" any time soon (i would know), but im sure when my shock and suspension system ages a little bit, im gonna have to start considering what you are talking about. and your story of the speedy hard corners with several ****ed up bumps is kind of the worst case senario. AGAIN, im not arguing with what you said, its all right.

But what im trying to say is that if the car's suspension system is in GOOD condition, and the driver doesnt throw him self thru an unnecessary, dangerous turn with bumps (which he shouldn't even if he had a brand new M3 CSL :P) then he's SAFE.

just my .2 cents ;)
