Safety Equipment - Bell Helmets M.8

The Nausicaa, 1993 Honda Prelude, track car project is continuing. We decided we would like to go for some Autocross (AutoX) and / or High Performance Driver Education (HPDE) events to work on the most important modification, the driver mod.
We signed up for an AutoX event with Cagalli Yula, 2014 Subaru BRZ, and decided now was a good time to invest in helmets.
Based off of recommendation of a friend who spends a lot of time doing track days I was looking at Simpson and Bell Helmets.
We elected to go with the Bell Helmets M.8 because of relative cost, Snell SA2015 homologation, M6 terminals (for later use with a Head And Neck Support [HANS] device), and availability in sizes small enough for my spouse's head.
