I just love the feel. Roads around here are crap, and going anything over half throttle on some of them would make SRA skip and jump around. With the IRS on the cobra it just soaks up the bumps and even with double the output of a GT sticks when you go full bore over the same roads that the GT would kick out on, even in a straight line.
Not to mention when you come out of a turn and hit it, the IRS just squats and grips, compared to solid rear that it just flings you sideways.
Im not much of a corner carver, but the feel of the cobra made me like taking some at some good speeds, its solidness and smoothness around corners is awesome. IMO i think IRS is just awesome for street driving.
