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.

Thank you for your letter. The JDM and Euro K20s are STL legal with the use of the USDM intake
manifold, 11.0:1 compression and 0.425 valve lift or the USDM OEM cam shaft. Aftermarket pistons are
allowed in STL to achieve the 11.0:1 compression ratio.
