harness yes, helmet no. using the 1 inch of belt stretch per 1 foot of harness belt. I could only possible hit 1 bar above my head (roll over) there is sfi padding there... which is intended for a helmet... If i removed that padding I should be in the clear...
course if something hits me hard enough to push the cage in, i could make contact. but at that point I'm pretty sure I'd rather be in a caged impreza, than a normal 99 Audi wagon.
1 or 2 rally guys gives me flack over that too. But 95% of rally drivers don't wear their helmets on transit .. probably 99% I only know 1 guy who wears his helmet during transit. (but 500 miles a year versus thousands for me)
good point.
