Hi
Looking for specs on OEM Cobalt SS rear springs vs the HHR SS. Want to lower the back of my HHR SS about maybe 1 1/2" using GM parts.
The GM P/N's are:
05-07 Cobalt Sport 10390024
05-07 Cobalt SS 22705489
08-09 Cobalt SS 25821162
2010 HHR SS 15938616
Thanks

 

How much are you looking to spend?

 

the 08-10 ss springs trim the lowest of all the part numbers quoted. I doubt very much you will get 1.5 inches lower however

 

if you want to get that low on oem springs better break out the torch









dont break out the torch

 

but seriously, break out the torch.

 

I was using 1 1/2" as a reference. Realistically 1" is more like it.
You say the 08-10 SS spring. Is that the Cobalt one?
If it is, what's it's spec vs the HHR SS?
