Went to Track Night in America at Thunder Hill last week. I had a great time, but at the end of the second run, I started to hear some noise at the front of the car. When I apply full throttle and rev over 3000rpms, the noise appeared. I have no idea where does it come from. When I drove back to home, I did several pulls, but I couldn't reproduce this noise anymore. It started at the beginning of this video, but during the last lap (after 3:40), it become very noticeable. I don't know if anyone could point to me what might go wrong on my car. Thanks.
