I have the opportunity to pick up some eibachs that were on a G5 GT and when i looked them up to see if they would fit my non G85 Redline it couldnt find the name on there. You SS guys dont understand what its like to be the red headed step child as a redline owner and get no info. Most is by trial and error. They springs say they are for Cobalt, SS, G5 and HHR...im guessing they will fit i just know the ION always a little diff than the other cars. I checked the redline forums and that forum is slowly dying so its not as active as it used to be. Havent heard anything yet. And info would be a great help, thanks
