The Quicken Loans 400 is a 400-mile NASCAR Sprint Cup Series stock car race held annually at Michigan International Speedway in Brooklyn, Michigan, and it is the first of two Sprint Cup races at Michigan. In 2006, 3M signed a three-year agreement to sponsor the race, but after one year moved its sponsorship to the August race. Starting with the 2008 race, LifeLock had title sponsorship rights for three years pending the announcement by the speedway, but left after two. The LifeLock 400 was the name of the race formerly known as the Banquet 400 in 2007. Since 2012, Quicken Loans sponsors the race for June.
This particular event had one of the longer title sponsorship arrangements. Miller Brewing Company sponsored the race from 1984-1998.
The 1999 race, won by Dale Jarrett, went without a caution. At an average speed of 173.997 mph, it set the NASCAR all-time record for a 400-mile race.
