I'll be putting this together slowly as i have time. I'll do my best to make a breakdown of all the performance options available. Please ask questions here, but i'll request your post be deleted if it's a common question that can be answered in a quick search.

I'm too tired of misinformation and the same thread 100 times asking which springs are best and which shocks/struts to get...

Factory Components

FE5 suspension - 2005-07 years
24-mm front stabilizer bar
FE5 shocks and struts. The springs may be different from some FE3 models.
Larger front end links

FE5 suspension - 2008 and up years
24-mm rear stabilizer bar
NEW FE5(LNF) shocks, struts, and springs.
Updated front knuckle

Both SS/SC and SS/TC springs lower the car by ONLY 10mm. That's less than half an inch.

SS/TC springs are ~30% stiffer than the SC springs.

Either one will be a great upgrade to any FE1/FE3 car. SS/SC stuff can be had cheaply, SS/TC stuff is better.

The alloy FE5 arms are an excellent upgrade to any FE1/FE3 Balt or Ion.
(Keep in mind if installed on an Ion, they will increase camber a fair amount)
Good read on Cobalt Front Suspension by Qwikredline

LNF/FE5 Part numbers
Sway bar: 15782696
Clamps: 10389617(same as 06-07 FE5)
Insulators: 25847760
Rear Axle: 25864579
Links: 20784688( ALL FE5 same)
Struts: 19181044/19181043(L/R)
Shocks: 25793745
Frt Springs: 25833647(L/R same)
Rr Springs: 25821162
Lower control arm: 25930725/15803767( L/R, right same on ALL FE5)
Knuckle: 25923942/25923941(L/R, unique to LNF)
And just get either SSC or Canuck Motorsport springs to couple with the struts and shocks. That's what I've got and I really like the way it handles.

Dude, you totally changed your post after I replied.

I'll see if I can find spring rates somewhere. CSS probably has the answer.

According to qwikredline at CobaltSS(dot)net:

qwikredline said:
its a rising rate....from 250 at 11 inches to 710 at 8 inches compression....
Maybe @Coby7 knows what it is or has access to a specs sheet somewhere?

Sweet. Thanks dude. I couldn't find the rate.

I still wanna swap my suspension with SS parts.

But I don't think the SS or any Cobalts came with a rear sway bar.

You might wanna just go with the LNF/FE5 struts and shocks paired with SSC or CM springs. Those are the only parts that are really required. It doesn't hurt to do everything else as well, but you don't need to.

Struts and shocks should be real affordable at Amazon, and the CM springs are only like $180 shipped.

Sweet. Thanks dude. I'll check out the prices for those parts and add a rear sway bar as well.
