Richard Childress Racing will appeal the six-week suspension of Craig Smokstad (car chief for Paul Menard's No. 27 NASCAR Sprint Cup Series car) and Grant Hutchens (crew member for the No. 27 car), the team has informed NASCAR.
RCR will not appeal the $100,000 fine and six-week suspension of crew chief Slugger Labbe, and it will not appeal the loss of 25 championship driver and 25 championship owner points, according to NASCAR.
Menard's car was taken back to NASCAR's research and development center after last month's race at Michigan. NASCAR said the frame rails had been intentionally modified in an effort to deceive inspectors.
The appeal is scheduled for Monday at the NASCAR Research and Development Center.
