Took the 'Balt out for a pretty hard run today on an 8 mile stretch of back country road with close to 50 turns chicanes and undulations. It was still a little too cold for my summer tires, but I felt more confident in the turns without the body roll, and the handling was exactly the same as stock if not better (plus I had my 185lb roommate in the car with me). I'll post pics of the drop sooner or later.

Lowering springs; because it is a progressive spring....

Hear is our specs of compression. Although everyone drives differently.

Front: 115 - 200 lbs/per inch.

Rears 50 -180 lbs/ per inch.
Thought I'd provide info for stock TC spring rates.

Front: Linear 154 Lbs (27 N/mm)
Rear: Progressive 160-228 lbs (28-40N/mm)

The MacPherson strut independent front suspension uses SS-specific gas-charged twin-tube struts; unique steering knuckles with optimized geometry; 27 N/mm linear coil springs with specific damper tuning; stiffer control arm handling and stabilizer bar bushings; and a direct-acting, 24-mm solid stabilizer bar. At the rear, the SS’s semi-trailing twist beam axle uses monotube gas-charged shocks with specific damper tuning, a 24-mm solid stabilizer bar, stiffer axle bushings and multi-rate coil springs (28-40 N/mm). StabiliTrak electronic stability control and traction control are standard

As the springs settled, I have about 2 fingers distance between the tire and the fender (stock ss/tc wheels with 235/40/18's). Some rubbing issues in the front when turning to lock, but nothing while driving. I'll take some pics shortly.
See my previous post on TC rates. These are about stock spring rate on front, but MUCH softer in the rear. You want the STIFFER rear vs front this car..these are softer rear vs front.

Agreed. Too low, and too soft. But I guess if you don't care about handling, or banging the exhaust against the beam, it's fine...

Drop rates on the our GTF springs. Front / Rear: -35mm/-40mm
Haven't had any issues with exhaust piping coming into contact with the rear beam
with all spec models.. products have been tested rigorously during the R and D process several years back .
Thanks!

These were really designed with 05-07 cobalts on mind..not TCs which have stock spring rates that 20% higher. From the pic of the TC rear here, these springs are not desireable. Perhaps the other type springs you offer (less drop) would be better for the TC?

I've had them for about a year on my TC and they're great. Handle like a dream and look great. My only gripe: Tires rub a lot in the rear when i have a rear seat passenger and i rolled. But i still wouldn't switch to any other spring.

i think that silver ss looks good slammed.
why is it lower than the black one?
if they would lower my car like the silver one, im wanting them. I guess at 30k miles i would need new struts as well

apparently, b&g springs are blowing struts prematurely, so I am in for these..
No Gt-s springs for the Cobalt ss-tc, just Gt-f model correct?

They are just called ARK GT springs. GT-F(ront) GT-R(ear) you get both when you order the ARK GT springs for the cobalt.
