One week after announcing a new policy of levying potentially stiffer penalties for substantial violations of technical regulations found in post-race inspection, NASCAR officials said Wednesday that the sanctioning body will not penalize Sprint Cup teams for minor infractions discovered during routine post-race laser inspection.  Last weekend at Chicagoland Speedway, the cars of race winner Martin Truex Junior and twelfth-place finisher Jimmie Johnson failed post-race inspection by small measurements that were slightly outside approved tolerances.  NASCAR said yesterday that it will not penalize those teams, which were among the nine subjected to post-race laser inspection following the opening round of the 2016 Chase … Truex was not the only winning driver whose vehicle failed post-race inspection at Chicagoland.  Kyle Busch won the Camping World Truck Series American Ethanol 225, but his Toyota lost in the inspection line afterwards.  Laser inspection is not used in the Truck Series, where Busch’s Tundra was found to be too low.  Minor penalties were handed down Wednesday, with crew chief Wes Ward fined six thousand dollars and the team docked ten championship points – dropping it from a tie for thirtieth into a tie for thirty-first in the owner standings.
