The No. 09 RAB Racing team and driver Kenny Wallace were penalized Tuesday after their Toyota entry failed post-race inspection after a season-best fourth-place finish in Sunday's NASCAR Nationwide Series event at Chicagoland Speedway.

 
Wallace and team owner Robby Benton were each stripped of six points for an improperly attached weight and failing to meet the minimum weight after the STP 300 at the Joliet, Ill., track. Crew chief Scott Zipadelli was also fined $10,000 and placed on probation until Sept. 5.
 
Additionally, car chief Travis Young was placed on probation until Sept. 5 for the same infractions.
 
Wallace has competed in nine of 18 Nationwide Series events this season with three top-10 finishes.
