This is from the website:
"The difference between Quick Fit and Quick Fit Pro? Quick Fit Pro harnesses have a different geometry and use a central cam lock which allows for use of the HANS device, where the standard Quick Fit is more of a standard 4 point shape using a typical buckle. Both are legal for road use in the USA, conforming to FMVSS209 which regulates primary vehicle restraints"

I would ask the head of tech in writing, way in advance, and if he/she approves I'd have that email handy for tech inspection.
