Congrats to all those who scored PB's! As others have said, it was a great day for it, just a pity so many people had dramas whether it be mechanical/noise or otherwise.
I was bitterly disappointed my day was cut short by mechanical gremins but what can you do (thats the last time I'm fitting gtst parts to a gtr hey bris). As for the whole noise thing, Snowie hit it on the head in that the club running the day has no control over the matter. So many things effect the noise reading...clouds, wind direction blah, blah its hard to know what pushes one car over the limit and not others. I've said it before but I will say it again...as far as I am concerned noise limits do not belong on a trackday. You go there to see how fast you and your car is....not to back off at the location where a sound meter is
