Richard Childress Racing will appeal the penalties assessed by NASCAR to Ryan Newman's No. 31 team for altered tires used in last month's Sprint Cup Series race at Auto Club Speedway in Fontana, California.
On Tuesday, NASCAR suspended crew chief Luke Lambert, tire technician James Bender and engineer Philip Surgen for the next six races and placed them on probation until Dec. 31. Lambert was also fined $125,000. Newman and team owner Richard Childress were each penalized with a loss of 75 points.
In NASCAR's 2015 Sprint Cup Series rule book, Newman's team violated section 20.16.A (wheels and tires) - any device, modification, or procedure to the tire or wheel, including the valve stem hardware, that is used to release pressure, beyond normal pressure adjustments, from the tire and/or inner shield, will not be permitted. The team also violated section 20.16.2.F (tires) - modifications to the tires, by treatment or any other means, will not be permitted.
The rule infractions resulted in a P5 level penalty on NASCAR's six-level penalty scale.
