Without a doubt, the D series is one of Honda's most underrated engines - it is compact, incredibly simple and remains affordable do modify. The D SERIES CUP was born in 2023 to give D series owners a chance to be competitive in a class of its own and what started off as a joke between mates became reality! The 2024 and 2025 seasons saw a complete 4 round schedule, rotating between popular circuits; SMSP Amaroo, Pheasant Wood Circuit, Luddenham Raceway and Winton Motor Raceway. 2025 was a huge year of growth for the DSC. Not only in attendance, but more importantly a community encapsulating the spirit of racing.
D SERIES CUP is a time attack event, where competitors compete for the fastest single lap time.
We do not race door to door.

The D SERIES classing structure, rules and regulations in 2026 will remain the same. The competition is close in both classes, it awards commitment to development of the D series platform and this is good for the competition. With current numbers, the two class structure is simple and easy for us to manage. Limited class will be restricted to a naturally aspirated D series and 200TW tyres. Please refer to Class Regulations below.
For the first time in 2026, the JAZZ CUP will run alongside DSC as a supporting category. Jazz competitors can accumulate points at 4 rounds to win the first ever Jazz Cup championship, a carbon trophy and bragging rights. There will be no classing structure in 2026. Run what you brung; daily drivers, turbochargers, sequentials, stage 4 tunes - anything L SERIES Jazz is welcome.
We thank you for being apart of this community! Here's to faster and closer racing for 2026!
