Established in 1987, formally the Kumho BMW Championship, they joined the CSCC at the start of 2024. Grids grew, as a result 2025 will see all rounds 'stand-alone', with no shared races with other categories. A renewed interest from MINI drivers will see revised classes and regulations introduced, with reverse grids for classes R53 and R56, as well as other ways to balance performance.

​

Most rounds of the Ramair BMW Championship will feature a 20 minute qualifying session and two 20 minute races. Some rounds will be on a single day, others spread across the weekend, for a more social aspect. All cars are eligible for multiple other CSCC racing series, with additional races at the same event being half price.​​​
