It took three attempts to "beat" Sport Plus with DSC on, however, so the sysem is well-calibrated. Braking rating Excellent Braking comments Medium-firm pedal with little idle stroke and virtually no fade until the fifth stop. How does BMW do this with single-piston calipers and a 4, 800-pound vehicle? Handling rating Good Handling comments Skid pad: With DSC off, the GT tiptoes in understeer. Decent grip, and when Sport Plus mode is selected, the steering feels (more or less) linear and "normal." With DSC on and "Normal" mode selected, steering input (and effort) are decreased. DSC first applies brakes, then closes throttle to quell understeer. Slalom: In Normal mode with DSC on, the yaw response is incongruous with the minimal steering input. That said, the DSC is perhaps one of the best I've tested in that it makes the GT go EXACTLY where the steering tells it to go without the usual overcorrections or stumbling of other systems. With DSC off, the GT doesn't feel as massive as it truly is. Balance is remarkably neutral with slight understeer on the limit.
