Richard Petty believes that someone must have told NASCAR about the unapproved parts that Penske Racing brought to Texas Motor Speedway for last weekend's race.
The NASCAR veteran said Friday at Kansas Speedway that Brad Keselowski and Joey Logano had already passed "two or three inspections and hadn't been caught," leading him to believe that someone must have told NASCAR about the changes to their rear-end housings.
NASCAR has penalized Penske Racing with six-race suspensions for seven crew members of Keselowski and Logano, along with $200,000 in fines and the loss of 25 championship points.
The suspensions are on hold as the team appeals, so the entire teams for Keselowski's No. 2 Ford and Logano's No. 22 are on hand at Kansas Speedway.
