Regarding helmets, most clubs require a helmet no older than the Snell date of within the past 10-years. So, current oldest would be Snell 2010... good through 2020 (they only come in 5-year updates... 2015 most recent.. and then good through 2025).

Some clubs may have allowances -- its an "insurance" issue beyond the club's control. Check with every club's requirements before you intend to enter and get on the track.
