[Land-speed] 2008 rule book question

[Elon]

Can different thickness of padding be used to accommodate different drivers
with different sizes of helmets? Or is the 2 in. STRUCTURE dimensions the
actual clearance between the steel tubing and the helmet?



I see different padding systems in IRL, NASCAR, etc. What kind of padding or
brand is suggested?



Thanks, Doug for your great question.   -Elon

Yesterday I tried to find the rule about the helmet area restriction of
