Confirmed inventory on hand at GM for both 2014 SS rear bar (28mm) and 2015-2017 SS bar (25mm). The 28mm bar has the same contour as production PPV bars. The 25mm bar is wider, same as found on 2015-2017 SS sedan. Both have the proper offset/kickout between the cradle bushings to clear the spare tire well.
The 2014 bar puts more load on the links and lower control arm link attachment brackets--using all 2014 SS parts takes care of this. The 2015-2017 bar, even though smaller, offers as much roll resistance as the 2014 configuration, provides better link durability and reduced harshness.
Both configurations require the bracket modification (or similar) described earlier in this thread to mount the bar to the cradle/crossmember.
using 2014 bar: (requires aftermarket links, or change to 2014 SS lower control arms & 2014 links)

NOTES:
1. For 2014 "narrow" bar, individual parts must be purchased.
2. Bushings & clamps from aftermarket may be substituted--typical clamps are slotted, allowing some adjustment vertically.
