From the NASCAR folks their ownselves...
NASCAR announced today that the No. 11, No. 18 and No. 20 teams that compete in the NASCAR Sprint Cup Series have been penalized for rules violations discovered during opening day inspection June 17 at Michigan International Speedway.
All three of the Joe Gibbs Racing cars were found to be in violation of Sections 12-1 (actions detrimental to stock car racing); 12-4-J (any determination by NASCAR officials that the race equipment used in an event does not conform to NASCAR rules detailed in Section 20 of the NASCAR rule book, or has not been approved by NASCAR prior to the event); and 20-5.5.4A (oil pan, failure to submit component) of the 2011 NASCAR Sprint Cup Series Rule Book.
As a result, the three crew chiefs – Mike Ford (No. 11 car), Dave Rogers (No. 18 car) and Greg Zipadelli (No. 20 car) have been fined $50,000 each and placed on NASCAR probation until Dec. 31. In addition, all three car chiefs – Chris Gillin (No. 11 car), Wesley Sherrill (No. 18 car) and Jason Shapiro (No. 20 car) along with Senior Vice President of Racing Operations Jimmy Makar have been placed on NASCAR probation until Dec. 31.
