Grunewald posted one of the fastest entry times of the race weekend, and maintained great speed and angle throughout the competition. Qualifying third out of 32 in Friday’s event, he went on to sixth seed in the finals the next evening. Grunewald was pleased with both his results and his MA-Z1’s, praising their incredible grip. Team owner Gene Jasper concurred: “They performed very well. The grip on the tires is excellent, and they have great longevity. We’ve had to change tires less often than others that we’ve used.”
