Splitter 4" rule

[Maddog]

Can someone clarify this rule...I sent an email to the CCC but never got a reply.


5.1.A3.2 Installation of a front splitter extending more than 4" past the forward most, sides (excluding side mirrors), of the OE vehicle body.


Does the 4" measurement start from point A or B from the attached pic?

I would say if point A if the forward most point, then from point A.
