Sharing data between teams also is a key to the success of the project.

"A big part of the Toyota program, especially in the (Camping World) Truck and Nationwide Series, is the amount of collaboration between the teams," said Steve Wickham, TRD's vice president of chassis operations. "In an ideal world, yes, we'd all have the same metric, and the drivers would all speak exactly the same language.

"This is one step toward that ultimate goal. At least they've got a number now, rather than a variation of text or numbers or finger gestures as to how the car's handling."

TRD is testing the application at the Nationwide and Truck Series levels before introducing it to the NASCAR Sprint Cup Series.
