damn, i figured if i heard it from across the track tht you would have heard it inside the car. i didn't feel it was my place to say anything since i'm not a expert. plus i asked other people around me if they heard it and they said no so i thought it was just me hearing things. i can still hear what my car is doing with my helmet on. sorry man , i just didn't think it was my place to say anything, plus my mind was else where on the miata and shit like that. by the time you went in i was out on the track and already forgot about it.
