I originally bought these for replacement on a 9-3 convertible, but switched them to the Aero Wagon (and the summer high performance tires from the Aero to the CV) to run a track event with the 9-3. Frankly, I liked the performance of the 9-5 better with narrower, taller tires and the performance of the convertible better with the more sporting tires.
In summary, the SP Sport were well rated by Tire Rack, and in my experience they performed pretty much in line with the TR testing. They are smooth riding, don't squeal during spirited cornering, and stick well in the wet. I am a snowbird, and therefore the tires are never driven on ice or snow. My only complaint: they have been discontinued in my size.
