ZL1 rear sway bar only on 2014 SS
 

So........I got the ZL1 sway bars from Parts Taxi. The front bar seem
about the same as the SS bar. The rear bar for sure larger in Diameter.
Why not just install the rear bar? Should eliminate any "push" for sure as
I have 255/45/20 on front(9 in wheel) & 275/40/20 on rear(10 in wheel)
Thoughts................

Good question.May be to much rear bias. SS bars are 23/24mm. ZL1 IS 25/28. Is a difference

That setup would likely be a bit oversteer bias at the point of traction loss. I would install the front bar as well; should make for a well balanced setup with your tire sizes.
