The information comes from GT-R chief engineer Kazutoshi Mizuno, who spoke recently with CAR. "The new mounts make the car feel more together in extreme circumstances," he said. "We've also changed the spring rates front and rear – it's a minute change, they're just 0.1kg/sq mm stiffer. But it means the movement of the suspension and powertrain are more perfectly tuned."
He also revealed that the GT-R will remain a global model and as such any modifications made in one market will be rolled-out in all other markets. The changes to the U.S. spec cars, for example, were added to the Japanese version less than a week after the modifications were made.
