so from what i've read the redesigned suspension on the TC despite its creaks and cracks is pretty much perfect for the car. if thats the case are sportlines merely an appearance thing or is there some performance gain?

 

as far as i know you will actually see a loss in performance....the suspension is perfect as is performance wise....

 

yea thats pretty much what i figured...ill be saving some money

 

There is no detriment. IDK what people are talking about when they say it is detrimental. I have proof fro man accelerometer that it A) absolutely does not hurt performance, most definitely B) Might actually increase performance. Now, I say might, because I saw a .17g difference on the accelerometer. Part of this, I am sure, is the temperature of the pavement, but not all of it. I went from seeing .88g on the stock springs, to 1.05g on the sportlines. This may be because i felt more confident in the car. There is less body roll, and it just sticks.

They ride a bit softer, yes, but they are progressive springs.

 

I have sportlines in my tc and the damn thing sticks to the road like glue. No loss in performance as far as i can tell. I have kids and with the car full of people the ride quality is still good. The only downfall is the front end is close to the ground and you need to be aware of that but the front was low to begin with anyhow.

 

i have sportlines on my balt as well. love em but im looking into getting new struts cause where i live the roads arent too smooth. other than that they are ballin

 

they look nice, thats about all i can say... I love the stock ride and behavior though

 

I have spotlines and it is a downgrade for hard cornering. However it rides smoother till you hit a bigger bump and it does look nice.

 

yeah really rough ride!! but they do look sexy as hell!!

 

Yeah, that is scientific. What were your constants? I pulled 1.10g on the stock suspension without issue. Driver training is WAY better than mods that give the illusion of confidence.

 

honestly i dont like these springs at all. h and r is the way to go.

 

h and r?

 

Nothing is perfect stock, its good but there is always room for improvement....

I've been to the track(not drag racing) with and without the sportlines, the track is just over 2 miles long not to technical but lots of nice twists and turns. I was turning good times with the stock suspension w/lighter oz rims and stock tire, after installing the sportlines my track times improved by just over 2 seconds. The car handles better with better turn in and less body roll through the twisties, I'm going to through the rear swaybar in and see if that helps out....

 

Sportlines are pretty stiff. your going to feel the road allot more.

Prob not such an increase in performance for an SS/TC tho.


Looks good lowered although

 

You must have never been in a car with a complete adjustable race set up, I had them
in my WRX, STi and Spec b which were all daily driven till I got the cobalt....

I agree with you completely....

 

It is an increase.

The car dives and squats less...and the rates are higher than the stock TC springs once they are compressed past the 'comfort ride' point.

With an added sway bar these cars stay flat as hell

 

I dont care what anyone says, any lowering spring is an improvement over stock....I have SSC's and konis and it handles 100x better/faster in corners.

 

ALL springs except for those that aren't released yet... besides the PROKIT

Have softer spring rates and actually worsen the handling of the car... whether you want to believe it or not it does...

I will be waiting for the TC specific springs to be released which shouldn't be too long

 

Now Koni's valving isn't as good and cannot be as dampened as the stock TC struts.

You got your improvement from handling being lowered with stiffer springs...but the stock TC dampening would be LIGHTYEARS better than koni yellows.

Trust me I looked into it.

Almost bought Koni yellows.

 

I disagree but i dont autocross or know what any of that means i drive 1/4 and take hard fast turns and it is better in my eyes so thats all that matters :P

 

The problem with 98% of the people who buy suspension bits don't know...I was one of em.


Kinda still am, but I ask first now.

 

i know suspension, just not autocrossing and whats best/worse. and the setup i have is alot better then stock around street corners...i do not race so there is no point for stock

 

I agree.

If you want a more aggressive look, and lowering the car's COG is still VERY beneficial, lowering springs will do that for the TC.

Pedders springs have the same exact spring rate as the TC stock springs, they just sit lower than stock.

And they ride better than sportlines...again(for the sportline naysayers)....ask me how I know

 

But ordering pedders springs if I remember is an odd process (dont you order each spring separate?)

And the valving of the stock TC struts is better then koni's? Well honestly I never liked koni's, I always paid for them before, each of those cars had a strut fail or 2 (and I didnt even track the cars)......I just deceided to never purchase Koni's again, not worth the premium price to me

 

I am not being a dick but am just trying to understand what you mean. That sentence seems to contradict its self. If a set up is better on a "autocross" track it would be better on the street aswell. So if you believe the stock set up is better for track purposes, what makes you think it wouldn't be better for street corners. I understand if you like the lower look of the springs if thats what you mean, but am unsure.

I think that is what I will be doing aswell. I will let the companies that do these kind of things handle it and see what they come up with. I would assume as long as the spring rate is the same or stiffer(to a point) they would out perform the stock springs.
