From Jayski:

All cars cleared after post race inspection: All of the cars that
NASCAR took back from Lowe's Motor Speedway following Saturday night's
NASCAR Banking 500 Sprint Cup race have cleared inspection and there
are no issues. The cars of race-winner #48-Jimmie Johnson and his
Hendrick Motorsports teammate #5-Mark Martin and Roush Fenway Racing's
#16-Greg Biffle were inspected Monday, and all were cleared, according
to a NASCAR spokesman.
