Jimmie Johnson's pit crew gets a makeover

   After a couple of slower-than-usual pit stops in last weekend’s Sprint Cup race at Darlington, S.C., two changes have been made to the pit crew for Jimmie Johnson’s No. 48 team.

   Beginning with this weekend’s NASCAR Sprint All-Star Race at Charlotte Motor Speedway, crew chief Chad Knaus named Cam Waugh the new front tire changer and David Mayo as the new rear tire changer.

   Both had been members of the No. 48’s auxiliary pit crew.

   Thursday’s changes come a week after Ryan Patton was named the new rear tire carrier on the No. 48.

   The reconstituted pit crew will get its first test Friday night during qualifying the for the all-star race, which includes a four-tire pit stop.
