I test drove a Cobalt SS 2.4 I'm not interested in that certain one but it had like a little bounce in it. I don't know if it was the road, but don't think so the only thing i could figure would be tires not balanced or could be where i'm not use to low profile tires?

 

17's with low pros will do it.

 

Rides smooth to me. For low profile tires on it, it's smooth.

 

i think my ss/sc rides like my old vehicle



that is a 93 silverado on 35's by the way
