[Land-speed] Helmet SIde Support Qs

[drmayf]

I want to try and be compliant with the new rules abot having less than 
2 inches side movement of the helmet. I think the rule is flawed, but I 
don't get a vote so I want to build a better supprt. I see the nascar 
seats have a pair of "horns" attached to that the helmet cannot rattle 
from side to side. I want to add something like that to my roll cage. a 
piece of flat aluminum bar stock that goes from the front bar back to 
the rear vertical bars on each side. Then I will put some foam pad on 
it. I think you can buy the SFI stuff in flat sheets and that may be my 
answer for padding. Question - how wide should this bar be?  1 inch? 2" 
Or More? How thick? 1/8 inch? 3/16"? 1/4" or more?  Thoughts or 
comments? No I am not going to creplace my seat with one of  one of 
thoses. Won't fit and they are way too expensive.  I am not worried 
abotu forward head movement, just side to side. Comment on this proposed 
solution please..
