From what I can see in some pictures, I noticed that some IRL and F1 cars are still using 3" wide shoulder harnesses with a HANS. Does anybody know why?
I am currently using a 3" wide harnesss with my older HANS, which does not have the "channel" or " guide" to help keep the belt from sliding off. I am wondering if I should stay with the 3" for that reason.
My mounting points are such that I can use either belt.
Thanks
Bob
