Hi.
Who here knows the current state of track day helmet regulations? Several track day organizers use the "Suitable" exception, and I've been thinking about trying to replace my old helmet with one that complies with the standards, but I'm not sure what requirements it has to follow. I had decided on BS6658 part A, but I've now learned that it's being phased out in December, and the most widely-used alternative, ECE 2205, doesn't apply to automobiles.
