Kurt Busch and his little brother Kyle grew up racing each other as kids and both drove for their father's race team.  That was the last time they were teammates.  Until this year.

This week, Kyle Busch Motorsports (KBM) announced that a new sponsor had joined the KBM team and that Kurt would join his brother in sharing driving duties in the NASCAR Nationwide Series.

The Monster Energy Company will be the primary sponsor of the No. 54 car.  Between the two drivers KBM will try make every one of the Nationwide Series and thereby attempt to capture the owner's championship in that series.

KBM has fielded a truck in the NASCAR Camping World Truck Series for the last couple of years and is moving to the Nationwide Series for the first time this season.

Kurt has never cared too much about running at the next level down from the Sprint Cup Series.  He has just 12 career Nationwide starts, but has won three times - his last as a fill-in for Brad Keselowski last year at Watkins Glen.

In the NASCAR Sprint Cup Series, Kyle will continue to drive for Joe Gibbs Racing with the M&Ms No. 18 and Kurt will begin his new job driving the Phoenix Racing No. 51 for James Finch.

But after a season in which the actions of both brothers made headlines, some wonder what this pairing may bring in 2012.  Perhaps the association will provide for a calming influence on each of them or do you think it may result in a volatile mix?  Time will tell.
