Some of the larger changes:
The aerodynamic shifts will be achieved through use of a common splitter and radiator oil cooler, which Stefanyshyn says will drop downforce by approximately 225 pounds (185 in the front, 40 rear) to a level of 1,650 pounds.
Changes are also in store for the NASCAR Xfinity Series, which will enter a transitional year for the new flange-fit composite bodies ahead of a full 2019 rollout. The series will also make improvements in the area of superspeedway bump-drafting, using a lower front fascia at Daytona and Talladega. The goal of mismatched front and rear bumper heights is to deter teams from locking on in the aerodynamic draft, a practice that’s currently officiated from race control.
The Xfinity tour will also expand the use of the aerodynamic package that debuted last year at Indianapolis Motor Speedway to largely positive reviews. That package — which utilized a taller rear spoiler, a restrictor plate and aero ducts to reduce the advantage of a leading car in ‘clean’ air — will also be used at Pocono Raceway and Michigan International Speedway this season.
Common pit guns will be in use for the 2018 season, in an effort to reduce the performance premium on equipment and place the emphasis on the pit crews’ athletic performance
