If you run fuel, or a center steer car with the engine in front, no floor over the transmission, you need the SA helmet.
I drive a center steer car. A Snell M is all that is required by NHRA. SA is only required with a supercharger, turbo, or nitrous I copied this right out of the rulebook.
Even though it shows the 2000's, If you go to rule amendments you can see they are dropped for 2012.
