While shopping for a competition harness, I came across this article on Schroth's web site on why 2" lap belts are safer than 3":

I also noticed that PCA Club Racing rules for 2006 include this change:
2. Allow FIA-approved harnesses with 2” lap belts in all cars.
I don't see any such change proposed for Z8 in 2006. Is this intentional or an oversight? Will I be turned away from an event if I show up with an FIA-approved harness with 2” lap belts?
