West Coast Racers is a dueling steel roller coaster located at Six Flags Magic Mountain theme 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 in a newly-themed section of the park named The Underground, which replaced the former Cyclone Bay.
