SFI Spec 16.1 seat belts
Need new belts soon. Per the rule book, belts must meet SFI 16.1. I see 16.1 belts with both 2" and 3" submarine belts. Are the 2" legal for stock? I can't find anything in the general regulations that specifies. I seem to recall a while back that the requirement was 3".
for clarity, my question is only in regard to the submarine belt....not the shoulder and lap belts.
Thanks.
