NASCAR's finest will let their hair down as they close the garage doors on the 2015 season.

FOX's Chris Hoenig has more in this week's "Fox in the Fast Lane."

It will be a fun holiday at the Busch household, as Kyle Busch's 2015 title makes Kurt and Kyle the first brothers to be crowned NASCAR champions since Terry and Bobby Labonte...

(Busch) "We're a championship family, it's definitely something that's pretty awesome and I look forward to being able to get back to Charlotte, North Carolina, and then go celebrate in Las Vegas and have a really good time there."

And the champ will show off his trophy in sin city at the NASCAR awards ceremony on December 4, hosted by Drew Carey of "The Price is Right."

He's is looking forward to hearing the word "champion" again... When he's told to "come on down."

(Busch) "With everyone saying champion or calling me champ or introducing me as the 2015 NASCAR Sprint Cup series champion, I've heard it a lot this weekend... It's really awesome to hear that."

The offseason can't arrive quick enough for Kyle Busch, who will have surgery to repair injuries which kept him out of the first eleven races of the year.
