I remember reading the SS has upgraded front contol arms. I wonder if they addressed the geometry and more solid mounting points of the SS over the standard HHR to address the wheel hop.

Stiffer bushings help a lot. the give of the rubber in most suspesion are the main reason for wheel hop and geometry is the second.
