West Coast Racers is a dueling steel roller coaster located at Six Flags Magic Mountain amusement park in Valencia, California. Manufactured by Premier Rides, the ride is a collaboration between West Coast Customs and Six Flags that was promoted as the world's first launch version of a racing roller coaster. After multiple delays and missing the 2019 summer season, the ride eventually debuted on December 21, 2019, in a series of preview events spanning several weeks. It officially opened to the public on January 9, 2020. West Coast Racers is located on the former site of Déjà Vu, an inverted roller coaster removed in 2011, within a newly-themed area called The Underground, formerly known as Cyclone Bay.
