nah i want the harder suspension on the front too

 

thats what she said lol

 

does anyone have pics of a SS S/C with the pro kit on it?

 

The Pro-kit sits up higher, but has a stiffer spring rate, which allows for increased handling. The Sportlines are made for people wanting to slam their cars, allowing a softer spring rate, which gives a smoother ride, but decreased handling... however the spring rate is slightly higher than stock.

Think about it this way, all the springs do for you is gives you your ride height. The actual main handling aspects of the car come from your sway bars and shocks/struts. But if you do lower the car, giving it a lower center of gravity (which does slightly increase handling), you will NEED a better dampening strut/shock to get the full benefits of your springs and have a setup that works. Trust me, the stock GM struts on these cars can barely handle the spring rate of the stock springs, not to mention the spring rates of an aftermarket spring. Something like the Konis are the best way to go in this situation.

 

exactly, i have my front strut brace already, i wanna do my springs, then the rear anti sway bar

 

hold up, i'm sorry but sportlines are known for their higher spring rate than the prokit. the both help increase handling, sportlines give it a more aggressive stance as well as even better handling capabilities than the prokit. prokit have a lower spring rate and are not ment to drop it that much but still stiffer than stock. u got em backwards as far as spring rates and ride quality go.

 

Sportlines drop the car lower, droping the car lower means you need stiffer springs so it won't bottom out. The pro kit is just a tad stiffer, the sportlines are more.

 

every damn shop i went to and asked about installing my sportlines said it'd be about $260 or more. is this about how much you guys paid? (those of you that didnt install it your self)

 

jsut got to your local auto parts store ask em for a spring compressor to rent and then use that for the fronts, and then just do the rears its not hard at all

 

why don't you need one for the rear's?

 

because you lift the rear, and the springs pretty much are all the was depressed and you unbolt the bolts and then the rear suspension comes down and the springs come right out, theres a how to somewhere on here

thanks for your help man. +rep

 

haha thanks +rep for u too if it allows me

 

I did all 4 without a spring compressor, you just need someone tough enough to compress the srping a little on the fronts.

 

yeah autozone or napa should have some spring compressors or u can take the entire front setup shock spring mount to like big o tire or something like that a place that does alignments and they can do it manually for about 3-40 bucks and even compress the new spring on for u.

 

word or ill get my uncle to jiggy rig it and make his own haha

 

COMPLETELY wrong on the spring rate part. Here, let me explain myself a little further, and break down what you're saying.

There is a big difference between spring rates, and stiffness. Stiffness is usually explained through the feel of a car, in which the Sportlines would give a stiffer feel on a stock set of struts due to the dampening abilities of the struts being next to nothing on stock springs, which kills them on lowering springs. But due to that extra low drop, you'll feel a "stiffer" ride due to having 0 dampening on the car, and you'll feel every bump in the road.

Ok, both will increase handling over stock to some degree, just by increasing the spring rate over stock, and lowering the car's center of gravity (which has less effect than you think).
The stance issue is relative to the car's owner, and has no effect in this conversation... that's a whole other topic.
The pro-kit however (given that a good set of dampeners is used with them) will provide better handling due to it's higher spring rate than the sportlines. Sportlines usually have a 350/135 rate, as the prokits have a 500/150 spring rate. Remember, this is typically, not exact specs. In fact, call up Eibach and get the rates from them, and you'll see what I mean. SO therefor, pro-kit > sportlines in handling characteristics.

Just because the spring makes the car not sit as low, doesn't mean it has a lower spring rate. In all honesty, please do your research and you'll find that spring rate and ride height have NOTHING to do with each other. Look at 4x4 vehicles, EXTREMELY low spring rates, but hold up a 5,000+ lb. vehicle 2 feet in the air.

I hope this cleared things up, and feel free to PM me or ask on here if you have any other comments or questions on this.

 

please do my home work? no please do your homework. u can match a set of koni's to either of those springs and the sportline will be stiffer, it dont matter about the dampening at all. the sportline and eibach will admit to it that the sportline are stiffer spring rate. prokits are designed for someone who wants a sportier ride but doesnt want to sacrifice much comfort. while the sportline is for people who want to go all out. ride hieght has nothing to do with it. if eibach wanted to lower it a full 2" then they would but they seen that at 2" it made handling worse so they put it to what they thought was better. I know that lowering car's center of gravity doesnt effect the handling charactoristics much. if you go to low it will have negitive effect. due to the car squating.

and why are you comparing a truck suspension to a car suspension? they are 2 seperate things. and being able to hold 5000+ lbs has to do with their chassis rigidity as well.

its plain and simple, sport line has a more agressive spring rate than the prokit. end of rant

 

That is how Eibach advertises them. I would hope the manufacturer woul know what they are selling.


Ok I have some bubble bursting to do. First off the spring rates WILL change depending on the car why would Eibach make the same spring rates for a Geo Metro that they do for a Dodge Ram Quad Cab? Come on man we may have been born at night but it wasn't last night! I just spent almost a half hour on Eibach web site and it says NOTHING about the spring rates being uniform for the Pro Kit or the Sportlines. Where did you get your info from? I think its seriously flawed.

Now HERE is what Eibach says about THIER springs that THEY make!
Pro Kit link...

Sportline link...
http://eibach.com/cgi-bin/htmlos.exe...80455900031073

I'm gonna contact Eibach directly and see if I can get the correct spring rates for the Pro Kit and the Sportlines.

 

burst my bubble never. cuz that really doesnt say much only the fact that the sportlines due state "race like handling" thats about it. we need a difinitive answer here. lol oh yeah your link for sportline dont work goes to prokit. heres the link

sportline

Not your bubble you doof! I'm agreeing with you!

Ok I just got off the phone with ABLE from Eibach and he says that the exact spring rates ARE NOT PUBLISHED AND CAN NOT BE GIVIN OUT.

BUT here's what he did say... That the Pro Kit is about 15% to 20% stiffer then stock where the Sportlines are 30% to 40% stiffer then stock. He said the Sportlines have a higher spring rate then the Pro Kit but he can not give out the exact #'s.

You just got an F on your homework Out1aw.

 

well heres what i got. i infact called eibach. i didnt exactly write down the spring rates so i might be off by a few % but that is roughly what they are. eibach sportline does have a higher spring rate than the prokit. damnit i hate it when i'm this good.

like ace ventura pet dic. says "can you feel it"

Spoke to adam at eibach, he states that the prokit offers a 10-20% spring rate over stock as the sportline offers a 25-35% over stock. Hence sportline having the higher spring rate.

score. yeah i was off on the percentage, i should have wrote it down. but damnit i love when I get an A, thats so hard to come by.


oh and Out1aw, if you would like to contact eibach themselves and inquire there number is 800-507-2338. thank you come again

 

It was ABLE not Adam. I talked to the same dude!


You forgot please drive thru. Yes you get an A

 

I love last minute homework. thats when i do good. i'm awsome at clutch time.

they can have mroe than 1 person working there. lets not call again and ask for the dudes name. haha.

and plus able adam they both start with an A, like my grade i got on my homework assignment. haha

 

True, ok I'll let it slide on his name.....but juuuust this once!
