KANSAS CITY, Kan. – Sprint Cup teams were warned about unapproved vehicle modifications during the race before Sunday’s Hollywood Casino 400 at Kansas Speedway.
Sprint Cup director Richard Buck addressed it during the prerace drivers meeting.
“I want to take a moment to just remind everybody of rule 10.7.1 in-race violations, unapproved vehicle modifications will not be permitted during the race event,” Buck said. “This includes but is not limited to pulling the side skirts, deforming the body parts of the car, manipulating the body parts, including slicing of the vehicle wraps, right-rear A post, anywhere on the car. Deliberately adding tape trips, etc.”
Buck actually was citing Rules 10.7.2 for In-Race Violations, specifically these two sections:
10.7.2.c: Unapproved vehicle/mechanical adjustment(s), modification(s), or failures will not be permitted during an Event. 10.7.2.d; Examples of unapproved vehicle/mechanical adjustment(s) or modification(s) include, but are not limited to the following body/vehicle components, as determined by the NASCAR Sprint Cup Series Managing Director in his/her sole judgment: Aerodynamic surfaces on or underneath the vehicle; Body component(s); Bumper covers; Fender flares; Hood or deck lid; Splitter; Spoiler; Side skirt(s); Window opening or rear glass.
This is at least the second time that teams have been warned before a 1.5-mile race about improper body modifications. Buck gave a similar warning in July before the Kentucky Speedway race, focusing on slicing vehicle wraps for aerodynamic advantages.
The penalty for illegal body modifications under yellow is a pit stop for repairs, restarting from the back and a drive-through penalty under green. The penalty under green is a stop for repairs under green.
Intrepid USA TODAY Sports reporter Brant James tweeted an explanation of “tape trips.”
