So are basicly Cobalts with better bodys???Meaning same suspension set up???

 

Yep, they're all based on the GM Delta global platform, along with the Pontiac G5/Pursuit and Saturn ION/Astra.

 

So any drop coils will work for both hhrs and cobalts?

 

Anyone have K sport set up??

 

They have different spring rates.

 

It depends who you ask. Some companies sell the same springs for them both, while some companies have specific HHR springs. I would personally go for HHR specific, as there is more weight and the balance is different. Im thinking that the cobalt springs would start to sag over time, but thats just a theory. I dont have any yet.

 

HHR curb weight: 3,155 lbs., GVWR: 4,173 lbs.

Cobalt curb weight: 2,730 lbs.

So each spring has to effectively handle about 100 lbs. more weight on the HHR than it does on the Cobalt. You can use the same springs, but the drop may be a little lower than the springs are advertised.

 

A base cobalt, ss cobalt, and hhr all have different springs, spring rates, and ride heights from the factory, in addition to the different weights.

 

yea, when doing a job like that, i wouldn't skimp on what is vehicle specific. you might be able to throw on a set of cobalt springs on the hhr, but what about when/and if you have a system in the back. when/if you gonna carry any cargo. i would think that you may do some bad in the long run, as far as gas per miles, wear and tear on the suspension, road handling, ect. someone correct me if im wrong but thats what i think.

 

Figure most of that is in the back for the add'l roof and cargo area and you will end up with reverse rake. Not cool IMO. And NOT good for handling.
