At the end of the 1983–84 season, Basket Rimini obtained promotion to Serie A1, the highest-tier level of the Italian basketball league system.

Multiple basketball champions played at Flaminio as opponents, such as Naismith Memorial Hall of Fame members Bob McAdoo, Oscar Schmidt, George Gervin, Dino Radja and Dominique Wilkins, as well as some NBA All-Stars including Mike Mitchell, Micheal Ray Richardson and Manu Ginóbili, and other great players like Darryl Dawkins and Toni Kukoč.

Between 1998 and 2000, Basket Rimini qualified also for the FIBA Korać Cup, the third-tier level club competition in European basketball.

The local basketball team (in the meantime renamed Basket Rimini Crabs) left the Palasport Flaminio in February 2003, moving to the new and more capacious 105 Stadium.

Through this new project, the team achieved two promotions in four years, therefore the Palasport Flaminio returned to hosting Serie A2 matches.
