A progressive spring is a progressive spring is a progressive spring. Everyone is going to have their opinions. Just know that no aftermarket spring is going to ride anywhere near the comfort level of a stock spring, they are not susposed to, they are not designed to, when you go into a corner and hit that pothole and it feels like your stomach just came up through your throat, It is susposed to be that way. Buy Eibach, K-sport, Tien, H&R they are all like this and most other companies also. I sell these and do this for a living, most of the time it is a matter of personal opinion and likeness the of brand. The only progressive spring that is made for the cobalt that do not have these charastics are the Pedders. They are designed differently, they are still progressive but unlike most companies mentioned above that have taken the time to develop a true performence spring, with no coil bind. The only other spring that was made for the Cobalt that had ride comfort was the Eibach pro kit, because they were a linear spring, just like your factory springs. Now from what I understand from last year at SEMA, Eibach hass now also become a cheapscate and their prokit is now a progressive setup.
So which spring did I buy, having access to allmost every brand, one that I do not sell. K-sports, why? Plane and simple the price and I cut a coil anyways so why spend more money and they are no different than any other cheap aftermarket spring, and they all have reverse rake with a 2-2.5. All of the aftermarket companies that make springs for the Cobalts have virtually the same spring and compression rate.
