Gap is the driver's best lap in a session against the fastest lap in their class in that same session (zero is fastest in class), shown as time lost and as a share of the lap, so conditions cancel out and tracks can be compared. Typical is the median session.

Letters to Fastrack

ITA/ITB/ITC/ITR/ITS/IT7 Request to allow 1.6 Miatas in ITA convert to 94-01 differential

#28983 from Ron Munnerlyn · Not recommended · Minutes (2020-12 Fastrack)

Thank you for your letter. Your request is not within the class philosophy. IT does not allow modification or replacement of
major components of the vehicle such as the differential carrier /rear end. Differentials are available that fit the 1.6L NA Miata's
(e.g. Kaaz, OS Giken), where many cars classed in IT must resort to modified OEM or very rare and hard to find differentials. This
is part of the "warts and all" philosophy that keeps the IT rules simple and limited. Allowing such a modification opens the door
to similar such changes across the range of IT classifications and potentially cascading requests for other cross-platform bolt-
ons. That is unwanted, the change is inconsistent with the class philosophy, and the justification for the change isn't even a real
problem for the car.
No one requests a "no performance advantage" item because it has no performance benefit. The CRB does not recommend this
