Alriht i knw tht the ss comes with front independent suspension. springs and struts. but wht does the rear have just springs and the twistbeam axle?

 

front - struts/springs, rear- shocks/springs.

 

rear suspension of the SS/ss is a semi independent twist beam with coil springs and antisway bar. base,ls,lt have no sway bar.

 

anyone know if it's the same as the ION RL? (minus the lightweight components, only basic design/compatibility)

 

Well Vita I am not sure what you mean by "lightweight components" but yes the Ion RL and Cobalt SS/sc share the same rear suspension/brakes, the cars are virtual twins on a mechanical level, they share many parts.

 

Will the eaibach Springs and those other H&R springs listed for the cobalt fit on an SS

 

they will but you need to remember that the SS ALREADY has lower, stiffer springs than normal....putting a base Cobalt sport spring in an SS may actually RAISE the car and SOFTEN the ride.

 

How exactally would coilovers work on this rear setup?

 

Well I saw an SS/SC with a lowered suspension at the Bash and it's definetly lower than stock. I am now sure about the ride. The guy is on this board and his car is picture of the month.
