Way better then expected..wasnt too sure about the dampers...but they worked too....supplier said the springs wont work on the HHR..considering all the other complaints about the rear being bouncy , I think these springs are great, no bounce and the dealer was wrong. Did your have the rubber insulaters on certain coils?

 

Sure did have the insulators, it needs them, if u have an SS look under at how compressed the back springs are, most are touching.. I have heard that the pedders bind and make noise but I have absolutely no issues with the sportlines.. I've had teins on my subu, espelir's on my s2k and the eibachs are a quality product.. Just glad we figured the sportlines for the cobalt ss would fit.. Thank u Modernperformance.com.. I've never had so many peeps comment on the SS. Very happy..

 

And Ive already been hauling heavy stuf with it with no problems....
