Hendrick cars going back to NASCAR's R&D Center

KANSAS CITY, Kan. -- The cars of Jimmie Johnson and Mark Martin are going back to the NASCAR Research and Development Center for another look.

Following Sunday's event at Kansas Speedway, NASCAR officials confirmed that four cars would be inspected at the circuit's research facility in Concord, N.C. The No. 14 of Tony Stewart will go as the race winner, and the No. 2 of Kurt Busch will go as the random. But NASCAR also will take the No. 48 of Johnson and the No. 5 of Martin, which were found to be perilously close to tolerance limits last week.

It's somewhat of a break from the routine for NASCAR, which typically takes only the race winner and a random car to the R&D Center for further inspection. NASCAR warned the teams of Johnson and Martin about being too close to the limit last week, although series officials insisted both vehicles were legal.
