Cars and Rules
Cars and Rules is your home to view the current rule book, rule book updates, recommended rule changes, and other memos. The content on this page will provide valuable information for Road Racing compliance in the SCCA.
SCCA Road Racing relies on the Road Racing Competition Board/RRCC (formerly the Club Racing Board/CRB) to establish rules, specifications, and standards for competition vehicles, as well as rules and standards for scheduling, organization, conduct, and supervision of Road Racing programs; and the licensing of drivers and officials. The RRCC supervises the execution of these rules and standards, and works in concert with the Road Racing Department to ensure such rules and procedures mesh smoothly to the benefit of the program and the participants. Each RRCC member has liaison responsibilities for specific Advisory Committees, representing the classes raced in SCCA's Road Racing programs, including American Sedan, B-Spec/C-Spec, Electric Vehicles, Formula/Sports Racer/Prototype, Grand Touring (GT), Improved Touring (IT), Production, Spec Miata/MX-5, Super Production (SP), Super Touring (ST), and Touring. The Advisory Committees review member input and recommend potential actions to the RRCC.

General Competition Rules (GCR)The SCCA Road Racing rulebook is called the General Competition Rules. The full version of the rulebook is updated monthly to incorporate rules changes made in Fastrack. You can download the latest version for 2026 below. This resource is for anyone interested in finding out more about racing with SCCA Road Racing, classifying their car, or understanding the technical regulations governing SCCA Road Racing. We do offer a printed version of the GCR for purchase here. The 2026 GCR online versions are available in Adobe Acrobat format, version 10 or later. Download the latest version of the Adobe Acrobat Reader here. The front of therulebook is often referred to as the Steward's section of the GCR as it includes regulations for events. If you are wanting to volunteer outside of the technical inspection and scrutineering specialty and don't need details on car classifications, you can download the Steward's Edition of the GCR here. |
