Unfortunately Shark Racing is unable to attend the Monroe Shocks and Struts Prelude to the Ironman at Federated Auto Parts Raceway at I-55 in Pevely, Mo. tonight due to mechanical difficulties with its hauler last night. The team is back underway and enroute to Missouri, and expects to be back in action at I-55 tomorrow night. Tonight's event is the first WoO race the team hasn't attended so far this season.
