2021 Spec-D Pro Drift Rule Book
For the 2021 season, Spec-D will be utilizing the 2021 Formula Drift Pro-Am Licensing Series Technical Rules and Regulations.
Although we try our best to avoid updates midseason, they may occur. Please verify you are using the most current version when reviewing throughout the season. Each version is denoted by the number immediately after the year (i.e. VX.X, with X representing the updates). NOTE: This edition of the regulations establishes a baseline safety requirement for all Formula Drift licensing affiliate series across North America. Formula Drift licensing affiliate series will dictate all other Technical Regulations not referred to in the following regulations. Participants, teams, drivers, and officials are strongly encouraged to review these rules carefully.
