All the best runs were made with traction control off*, but with prudent throttle modulation to keep the rear tires from evaporating. Wow, this thing is quick! *Note: Turning traction control off automatically engages Auto LSD, an electronic limited-slip function.
Not much to tell: very little ABS pulse or hum. Pedal stroke and firmness remained the same from first to last stop.
Our test truck had no owner's manual, and we didn't find the defeat mechanism for the stability control while at the track. Therefore, our slalom results came in lower than they otherwise would have. Nevertheless, steering is quick and precise, and the chassis is suited to dancing. Unlike slalom, where stability control was the limiting factor, it was the tires on the skid pad. An inexorable "push" develops that doesn't seem to awaken the sleeping electronic nanny.
