Teams will not need to replace the front splitter if it is broken off during a "car of tomorrow" race, NASCAR Nextel Cup Series Director John Darby said Thursday. Darby said he expect teams will want to have a front splitter – a shelf that sits underneath the front valence to adjust front downforce – on the car, but it won't be a requirement. So just as in the past, a car with a sawed off front end following a crash could be on the track. "The front splitter won't be mandatory," Darby said. "But remember, it is a huge tuning tool. They're going to do everything they can do to make sure that they have a front splitter." Teams will have to replace the rear wing in the event it is damaged, just as they have to replace the rear spoiler on a current car.
