It 12yrs, My current helmet is a Simpson SA2005 and drag tech has only looked at it like twice since 2005. The tech for the standing mile and 1/2 mile events I've ran did check it.
The padding in mine is starting to dry rot so I've been looking at the Typhoon SA2020 helmets, Not terribly expensive at $165.
Depending on the track, they might let you run with with a M2020, that's a motorcycle spec helmet, the major difference between SA and M spec is the SA is fire rated and impact rated for bouncing of a roll bar. ergo why M spec is a tad cheaper than a SA spec.
If you're stock you probably wont need a fire jacket/gloves but if yer' pullied and pushing 9's, Racequip jackets and gloves are cheap.
Good luck.
