what lowering springs for a 09 SS/TC
^I go to car shows at least once a week. I have never been to an autocross event.
To me cosmetics is pretty important but I do plan on autocrossing at some opint and I dont want to completely screw up my cars handling.
Whats the best spring to gget for the SS/TC that will lower it while maintaining performance

^^ I wanted the same thing as you. From what I read, the Eibach was the stiffest and better for the track while the SSC was a bit "like stock" so I assumed if its as good as stock, whats the issue. Now is Maven is saying sport lines are softer then ssc, I dunno. I will be tracking once a month probably until sept so 6 times. I will see when I am out there.
I just looked into the Pedders and I couldnt find Cobalt on their sight. But according to other forums they drop the same as the pro-kit would. none in front and .5 in back. Looking for a little more than that...lol.
So far it looks like im going with Sportlines or SSC
Its not worth dropping a car for .5 inches considering no matter what I do its not gonna increase handling only decrease it

Okay lets seee....
Ive heard that before about them.
I didnt mention SSC's......I said SS/SC are slightly stiffer than Sportlines...SS/SC as in LSJ Cobalt
Sportlines are roughly the same, lil softer, than stock SS/SC(LSJ) springs....they are softer than SS/TC(LNF) springs, by a noticeable margin....because LNF springs are over 20% stiffer than LSJ springs....so therefore Sportlines are at least 20% softer than LNF springs....got it?
Sportlines definitely ride softer than stock LNF springs, but they DO actually reduce body roll a little bit and they virtually eliminate brake dive. Youre talking about front bar? Thats what they do...LOL My car would just burn off the inside tire with the LNF springs and LNF bar....
Pedders if you want the closest to stock ride and are okay with just under an inch in the front and just over an inch in the back
that Pedders drop 7/8" in front and just over 1" in rear on a TC, I switched from LNF springs to the Pedders and thats how much I dropped, Steddy has seen and driven in my car There is definitely a noticeable drop between the Pedders and the LNF springs, and they ride almost identically(they are supposed to be almost exactly the same rate)
220006 and 220007 are the part numbers, you need 2 of each.

Hmm thats not the experience I had.. I have a much firmer ride now (going over bumps) and the body doesnt roll as much (this was before the sway bar, which was a bad decision, dont get it). Strange.
Stock springs = onramp I could take at 75-80max, nothing changed but new springs = same onramp at 90, sway bars = same ramp at 95. The reason I say stay away from the Eibach is on really tight turns - you can actually feel the inside wheel lift when you lose traction. Its too much bar.

WOOT! The information I have been waiting to find. lol
I guess I will be looking into some Pedders, as I want to drop it/ level the look out a little but did not want to lose any or very little performance from doing it.
Thank You for the information Maven

Thank You for the information Maven
And thank you Maven, your full of information
Sad thing is im stubborn and still probobly gonna go sportlines
If those pedders only dropped it a little more They would by far be the most sought after springs. Im suprised i never heard of them before. Wouldnt it be cool if you could just take the TC springs and just chop like 2 inches off of them
^read the last page.

that way youll have a lower stiff spring

If you cut the TC springs theyll get even stiffer
Sportlines will make the SS/TC ride even smoother. Pedders ride almost exactly the same.
Sportlines are good springs, make no mistake, they are softer than SS/TC stock springs though, so if ride quality and looks are more important that ultimate handling go with Sportlines I dont think youll be disappointed.

Any word on the Canuck Motorsports springs??

I always thought the Eibachs would have handled better than stock. Good info guys!

I just put the Sportlines on my TC. I gotta say, the ride is a bit rougher on the choppy roads, and smoother on the smooth roads. The handling is amazing. I figured since the ride changed for the softer, that i would not like it. But, it is much more planted, and responsive. I like it... alot.

^apparently its a progressive spring design. This means its soft while 1st being compressed and as it compresses the stiffness builds greatly. This gives it a comfterble ride over small bumps but under big bumps or situations like sharp turns where you have alot of body roll and spring compressing, it should hold up pretty well for the spring will compress a little easily and then get very stiff
I see your logic in your comment, but you are wrong, sorry. There is less body roll, and the car plants much more responsively. The ride is not really softer. It feels much like stock.
Also, my accelerometer has proven a minimum of .5g gain in the curves. If you want to argue with that, have fun losing.

Oh really? Do you have Sportlines?

I could be wrong but with me and my SSC springs, it feels softer and sloppier. If you got a 0.5g gain, then I would say yes they are better. I am not gonna argue what spring does what, I just want to reveal if the stock ss/tc spring is better then the other springs available.
The camber kit is not needed. But an alignment surely is. I would give it a week or 2 to settle out before you do your alignment though. Just to be sure everything is within specs when its done.
I believe TC spring is probobly the best. I think its the stiffest. It just doesnt offer any drop for an upgrade
I have the Pedders and my friend(Steddy) has the Sportlines, over small ripples and slow speed bumps the Sportlines are smoother than stock SS/TC, and a little smoother than Pedders. Its hard to tell exactly which springs has the best total perfomance because we are on different tires but its pretty close even though he has much better tires. As far as big bumps and truly nasty roads the Pedders by far handle that better. The sportlines dont like nasty sections of road, I think its partially due to the design that the Sportlines are lower and that the Pedders have more active coils, the two springs look completely diferent, they have different designs.

I wish there was an upgraded spring (higher rate) that lowered the same amount as the Sportlines.. Without going to coilovers of course.
Sportlines definitely dont like bumpy roads. It feels like you have no suspension at all. However on smooth roads/small bumps, they ride very very well. There is a dip in the road on the way into work, and if I hit it at any reasonable speed (50 or 60mph) I usually get an "uuumph" out of anyone in the car when I go over it.. myself included.
