Oy...I can't believe anyone would somehow think the CTS and Malibu share anything except for being GM vehicles. One is RWD, the other is FWD. Both have COMPLETELY different platforms and suspension designs front and rear.the malibu from SEMA was dropped using Eibach springs for a solstice, which is the same as a skyy. Also, the malibu is on the same chassis and suspension design as a CTS, therefor making simple parts such as Eibach drop coils interchangable with the Malibu.
I work at a chevy dealership in service, and own one, and have owned bagged and bodydropped vehicles before so I know suspensions. I'm actually going to juice my malibu, so I'll have the lowest and cut it up to tuck 22's in the fenders
