I was building RWD ATS' on Cadillacs website and noticed that the 2.0T Premium and the 3.6 Premium have Magnetic Ride Control which has the Performance Suspension which has the FE3 suspension. The website gives all that information on those 2 cars. The other 7 RWD cars only have listed that they have Sport Suspensions but they make no mention of the FE1 or the FE2. Does anyone have any info as to which cars get which suspensions?
