NASCAR to switch from rear wing to rear spoiler

NASCAR informed teams Friday that it has scheduled an open test at Charlotte Motor Speedway as part of an upcoming transition from a rear wing to a rear spoiler.

The change had been discussed individually with teams, but nothing had been formally announced before the Friday memo to crew chiefs from Cup Series director John Darby. To help put some of the rumor mills to rest, I am sending you the following facts as they relate to changes for 2010," Darby wrote in the memo. "We will be transitioning from the usage of the current wing to an aluminum spoiler."
