I had my first track day with the Genesis Sedan today at Thunderhill Raceway for a Speed Dynamics event (great group!). I wasn't trying to push the car too hard but got noticeably faster throughout the day and the upgraded brakes didn't fade one bit. I also got a chance to dyno the car with the results below. The car kept shifting early on the dyno (at 6200rpm) so peak power is likely a bit higher closer to redline.
