Best in-car audio: Kasey Kahne thinks Dale Jr. should 'mind his own (expletive) business'

BY foxsports • March 19, 2014

Bristol Motor Speedway brings out the best in drivers, as tempers usually flare in the confines of 'The World's Fastest Half-Mile.' It was no different on Sunday ... even between teammates.  

Dale Earnhardt Jr. had some questions about Kasey Kahne. Kahne, however, had a suggestion for Junior. And Kevin Harvick wanted someone to remind the No. 10 what (expletive) team she's on. 

All of this - and more - in this week's edition of NASCAR Race Hub's "Radioactive."
