Looking to do this track day myself. beleive full face helmets are required for this track day, a requirement by Goodwood I was told. BHM are offering helmets on the paperwork they emailed to me, maybe you can book one of those? Also looking to get a set of extra cans for my car as I think my car is noisy and so liklely to fail the noise test. Previous experience at Goodwood says they are balck and white about noise levels. And they always seemed to be looking over my shoulder when testing in the past. Their scrutineers do build up a knowledge of vaious cars and the noise they make.
