Well from looking at the spec changes it's easy to see why the handling has changed. The rear tires have grown in proportion to the fronts, the rear suspension has lost a little bit of roll resistance and the front has gained some. That should shift the overall balance of the car a bit away from oversteer but the magnitude of the changes doesn't sound like it's much to make the overall feel of the car "soft."
