But not using either of them could cause an unnecessary amount of R&D to on suspension components. You move a few pieces a few fractions of an inch or more here and there and the ripple effect comes into play. Suspension geometries are thrown way off from simple spring changes, let alone wheelbase changes.

Bottom line is that if it gets put on a ATS wheelbase it's going to lose weight. Just FYI the CTS lost over 200lbs by switching to Alpha. I know Zeta and CTS are not the exact same but they are really close. Also for what it's worth the new CTS on Alpha has dimensions of 114.6wheelbase, 195.5 length, 72.2 width and 57.2height. The old CTS is 113.4 wheelbase, 191.6 length, 72.5 width, and 58 height. As you can see the car gained size in many areas yet lost weight. I think GM would have to screw up royally not to drop weight in the 6th gen.
